net-ftp/pure-ftpd: migrate to stand-alone configuration

This bump changed at lot of things:
* Deprecating configuration via 'conf.d', since not all option are
  available via command line. User will be informed about this.
* Using '/etc/pure-ftpd.conf' as main configuration file, since more
  option are available here.
* Adding pure-certd init script and config script for using SNI via FTP
* Splitting Uploadscript into it's own init script
* Simplified init script by removing much old stuff, which it seems,
  that it's not needed any more today. At least in my tests.
* Adding SVCNAME support.
* Removed sed for MAX_USER_LENGTH, as it's already default
* Removed DOCS for default docs
* Removed keepdir, since it looks like it's not needed anymore
* Overhauled eBuild
