make .gnulib a submodule

This makes it so we record (via a git submodule)
a snapshot of whatever version of gnulib we're using,
and none of gnulib sources are in the libvirt repository.
The result is that we have as much reproducibility as when
we version-controlled imported copies of the gnulib sources,
but without the hassle of the manual process we used when
syncing with upstream.

Note that when you clone libvirt, you get only the libvirt
repository, but when you first run ./bootstrap, it clones
gnulib (at the SHA1 recorded via the submodule), creating
the .gnulib/ hierarchy.  Then, the bootstrap script runs
gnulib-tool to populate gnulib/ with the files that make
up the selected modules.

Put the following in your ~/.gitconfig file.
[alias]
  syncsub = submodule foreach git pull origin master

The update procedure is simple:
  git syncsub
  ...build & test...
  git commit -m 'gnulib: sync submodule to latest' .gnulib

* .gitmodules: New file.
* .gnulib: Initialize.
* bootstrap: Set up to use the new submodule.
Stop using --no-vc-files.
Don't remove .gitignore files.
Don't use or create .cvsignore.
Diagnose an invalid --gnulib-srcdir=DIR argument.
* build-aux/vc-list-files: Delete file, now pulled from gnulib.
* build-aux/useless-if-before-free: Likewise.
* po/POTFILES.in: Remove gnulib/lib/gai_strerror.c, since
it no longer contains translatable strings.
* gnulib/*: Remove gnulib/ hierarchy.

-/* alloca.c -- allocate automatically reclaimed memory
-   (Mostly) portable public-domain implementation -- D A Gwyn
-
-   This implementation of the PWB library alloca function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit,
-   was inspired by discussions with J. Q. Johnson of Cornell.
-   J.Otto Tennant <jot@cray.com> contributed the Cray support.
-
-   There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.  */

-/* An improved random number generation package.  In addition to the standard
-   rand()/srand() like interface, this package also has a special state info
-   interface.  The initstate() routine is called with a seed, an array of
-   bytes, and a count of how many bytes are being passed in; this array is
-   then initialized to contain information for random number generation with
-   that much state information.  Good sizes for the amount of state
-   information are 32, 64, 128, and 256 bytes.  The state can be switched by
-   calling the setstate() function with the same array as was initialized
-   with initstate().  By default, the package runs with 128 bytes of state
-   information and generates far better random numbers than a linear
-   congruential generator.  If the amount of state information is less than
-   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
-   state information is treated as an array of longs; the zeroth element of
-   the array is the type of R.N.G. being used (small integer); the remainder
-   of the array is the state information for the R.N.G.  Thus, 32 bytes of
-   state information will give 7 longs worth of state information, which will
-   allow a degree seven polynomial.  (Note: The zeroth word of state
-   information also has some other information stored in it; see setstate
-   for details).  The random number generation technique is a linear feedback
-   shift register approach, employing trinomials (since there are fewer terms
-   to sum up that way).  In this approach, the least significant bit of all
-   the numbers in the state table will act as a linear feedback shift register,
-   and will have period 2^deg - 1 (where deg is the degree of the polynomial
-   being used, assuming that the polynomial is irreducible and primitive).
-   The higher order bits will have longer periods, since their values are
-   also influenced by pseudo-random carries out of the lower bits.  The
-   total period of the generator is approximately deg*(2**deg - 1); thus
-   doubling the amount of state information has a vast influence on the
-   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
-   only good for large deg, when the period of the shift register is the
-   dominant factor.  With deg equal to seven, the period is actually much
-   longer than the 7*(2**7 - 1) predicted by this formula.  */
-
-
-
-/* For each of the currently supported random number generators, we have a
-   break value on the amount of state information (you need at least this many
-   bytes of state info to support this random number generator), a degree for
-   the polynomial (actually a trinomial) that the R.N.G. is based on, and
-   separation between the two lower order coefficients of the trinomial.  */

-/* Usage suggestions:
-
-   Programs that use <stdbool.h> should be aware of some limitations
-   and standards compliance issues.
-
-   Standards compliance:
-
-       - <stdbool.h> must be #included before 'bool', 'false', 'true'
-         can be used.
-
-       - You cannot assume that sizeof (bool) == 1.
-
-       - Programs should not undefine the macros bool, true, and false,
-         as C99 lists that as an "obsolescent feature".
-
-   Limitations of this substitute, when used in a C89 environment:
-
-       - <stdbool.h> must be #included before the '_Bool' type can be used.
-
-       - You cannot assume that _Bool is a typedef; it might be a macro.
-
-       - Bit-fields of type 'bool' are not supported.  Portable code
-         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
-
-       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
-         performed in such a way that every nonzero value gets converted
-         to 'true', and zero gets converted to 'false'.  This doesn't work
-         with this substitute.  With this substitute, only the values 0 and 1
-         give the expected result when converted to _Bool' or 'bool'.
-
-   Also, it is suggested that programs use 'bool' rather than '_Bool';
-   this isn't required, but 'bool' is more common.  */

-   contexts, e.g., the top level.
-
-   Symbols ending in "__" are private to this header.
-
-   The code below uses several ideas.
-
-   * The first step is ((R) ? 1 : -1).  Given an expression R, of
-     integral or boolean or floating-point type, this yields an
-     expression of integral type, whose value is later verified to be
-     constant and nonnegative.
-
-   * Next this expression W is wrapped in a type
-     struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
-     If W is negative, this yields a compile-time error.  No compiler can
-     deal with a bit-field of negative size.
-
-     One might think that an array size check would have the same
-     effect, that is, that the type struct { unsigned int dummy[W]; }
-     would work as well.  However, inside a function, some compilers
-     (such as C++ compilers and GNU C) allow local parameters and
-     variables inside array size expressions.  With these compilers,
-     an array size check would not properly diagnose this misuse of
-     the verify macro:
-
-       void function (int n) { verify (n < 0); }
-
-   * For the verify macro, the struct verify_type__ will need to
-     somehow be embedded into a declaration.  To be portable, this
-     declaration must declare an object, a constant, a function, or a
-     typedef name.  If the declared entity uses the type directly,
-     such as in
-
-       struct dummy {...};
-       typedef struct {...} dummy;
-       extern struct {...} *dummy;
-       extern void dummy (struct {...} *);
-       extern struct {...} *dummy (void);
-
-     two uses of the verify macro would yield colliding declarations
-     if the entity names are not disambiguated.  A workaround is to
-     attach the current line number to the entity name:
-
-       #define GL_CONCAT0(x, y) x##y
-       #define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
-       extern struct {...} * GL_CONCAT(dummy,__LINE__);
-
-     But this has the problem that two invocations of verify from
-     within the same macro would collide, since the __LINE__ value
-     would be the same for both invocations.
-
-     A solution is to use the sizeof operator.  It yields a number,
-     getting rid of the identity of the type.  Declarations like
-
-       extern int dummy [sizeof (struct {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-     can be repeated.
-
-   * Should the implementation use a named struct or an unnamed struct?
-     Which of the following alternatives can be used?
-
-       extern int dummy [sizeof (struct {...})];
-       extern int dummy [sizeof (struct verify_type__ {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern void dummy (int [sizeof (struct verify_type__ {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-       extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
-
-     In the second and sixth case, the struct type is exported to the
-     outer scope; two such declarations therefore collide.  GCC warns
-     about the first, third, and fourth cases.  So the only remaining
-     possibility is the fifth case:
-
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-   * This implementation exploits the fact that GCC does not warn about
-     the last declaration mentioned above.  If a future version of GCC
-     introduces a warning for this, the problem could be worked around
-     by using code specialized to GCC, e.g.,:
-
-       #if 4 <= __GNUC__
-       # define verify(R) \
-	   extern int (* verify_function__ (void)) \
-		      [__builtin_constant_p (R) && (R) ? 1 : -1]
-       #endif
-
-   * In C++, any struct definition inside sizeof is invalid.
-     Use a template type to work around the problem.  */

-   Return 1.  */

-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

-dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
-dnl supports it in the special case that it is the first include directive in
-dnl the given file, or to 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.

-
-dnl This file defines some "once only" variants of standard autoconf macros.
-dnl   AC_CHECK_HEADERS_ONCE          like  AC_CHECK_HEADERS
-dnl   AC_CHECK_FUNCS_ONCE            like  AC_CHECK_FUNCS
-dnl   AC_CHECK_DECLS_ONCE            like  AC_CHECK_DECLS
-dnl   AC_REQUIRE([AC_FUNC_STRCOLL])  like  AC_FUNC_STRCOLL
-dnl The advantage is that the check for each of the headers/functions/decls
-dnl will be put only once into the 'configure' file. It keeps the size of
-dnl the 'configure' file down, and avoids redundant output when 'configure'
-dnl is run.
-dnl The drawback is that the checks cannot be conditionalized. If you write
-dnl   if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
-dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
-dnl empty, and the check will be inserted before the body of the AC_DEFUNed
-dnl function.
-
-dnl The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
-dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
-dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
-dnl headers at once, thus reducing the size of 'configure'. It is known to work
-dnl with autoconf 2.57..2.62 at least . The size reduction is ca. 9%.
-
-dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
-dnl with Autoconf 2.60 or greater. But note that autoconf's implementation of

-dnl Tests for a multithreading library to be used.
-dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
-dnl USE_PTH_THREADS, USE_WIN32_THREADS
-dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
-dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
-dnl libtool).
-dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
-dnl programs that really need multithread functionality. The difference
-dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
-dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
-dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
-dnl multithread-safe programs.
