contribs: enforce usage of gcc-4.2 instead of llvm-gcc-4.2 for libx264 to ensure proper linking on both PPC and x86 based Macs

Binary packages will need an update here.

Cosmetics: Remove need to (char*)"..." by making the target const, and replace a call to var_Get(bool) with var_GetBool.

Cosmetics, and pull finding the playlist sorting function back to top level. The meta_* functions are still wildly inefficient, though.

A thank you to the Xbmc authors who had this fixed in their version of Martin Kahr's class.

When reading a file:// URL from an xspf entry, store the decoded file path; else store the unmodified URL

Always keep album art URLs always encoded and decode the path when needed
Interfaces & plugins only use file paths
Playlist core extract attachment:// URLs (from file meta data), http:// or other (from meta data fetchers like lua) and cache them to a file

playlist sorting: for inline to work, the text has to be available. IE putting the function behind all others that use it isn't going to work, and marking forward declarations inline won't help fix it.
