[arch-dev-public] adding xdelta3 to repo

[Allan McRae]

Hi,

I am going to add xdelta3 to the repos.  It is a separate developmental 
branch to xdelta(1) that has recently been declared stable. xdelta3 can 
be installed alongside xdelta and following other distros it is probably 
best to have this as a separate package. Finally, xdelta3 is needed for 
the reworked delta implementation in pacman.

Thanks for you lack of objection...
Allan
