Juan RP 6256b34ccc Some changes that will appear in 0.5.0:
* Add proplib-0.4.1 source and use it in XBPS. This is to avoid
   an external dependency, so that we depend on the features of the
   internal library. This also means that proplib is not required anymore.

 * Added support to read/write gzip compressed plists by default, thanks
   to proplib-0.4 that gained new functionality.

That means that from now, XBPS will be able to write compressed gzip
plist files for all metadata related work. This will vastly reduce
bandwidth required for fetching remote repo's pkg index file and
binary packages.
