XBPS: LLVM/Clang, Apache packages

This is the list of recently added packages into the x86_64 official repository for XBPS:

• llvm-2.7 (provides some subpkgs: clang, clang-devel, llvm-docs). The clang static analyzer helped me to found some warnings on XBPS and Portable Proplib.
• apache-2.2.15 with the prefork MPM. A -devel subpkg to build modules is also provided.
• apache-mpm-{worker,event}-2.2.15: Apache httpd binaries that provide different MPMs.
• mod_fastcgi-2.4.6 - Apache 2.x module for the FastCGI protocol.

Along with some apache required dependencies (apr, apr-util), and some GNOME 2.30 updates, are
all related changes from this week in the xbps-src git repository.

I'm working in packaging MoinMoin with Apache/mod_fastcgi that I plan to use to document XBPS related stuff really soon.
