[pacman-dev] Round 2: Add delta information to libalpm.

[Nathan Jones]

Here are the updated patches for adding delta downloading to libalpm.

I had originally thought that if a delta could not be downloaded (due to
md5sum or file deleted on the server), the package file should be
downloaded instead. I decided not to do this because some users may be
annoyed at seeing a 7MB download size but end up downloading 100MB
openoffice package.

If the md5sum is not correct, the output is mangled a bit. I am not sure
what causes this.

Also, is it just me, or do 78% of the pactests fail?
