dev-libs/libxslt: apply several upstream patches, bug #558822

Apply security fixes, bug #558822 as well as patches from upstream as listed
in debian package.

Also rework python detection with AM_PATH_PYTHON for easier multiple python
support in the future. Handle examples like in libxml2.

+Subject: EXSLT function str:replace() is broken as-is
+
+the str:replace() function is no longer usable without a transform
+context. I take it from the bug report that it is not supposed to be used
+from plain XPath but only from XSLT according to the EXSLT specification.
+
+However, the previous implementation used to work in XPath and is still
+registered on an xmlXPathContext by the exsltStrXpathCtxtRegister()
+function. When called from plain XPath, it results in a memory error in
+line 526 (exsltStrReturnString()) of strings.c because xsltCreateRVT()
+returns NULL as an error indicator due to a NULL transform context being
+passed in, which was the return value from xsltXPathGetTransformContext() a
+bit further up (and the code doesn't validate that).
+
+Since fixing the function looks impossible, best is to remove it.
