alpm: add new alpm_find_satisfier function
whatprovides and splitdep were removed, so depcmp alone is quite useless
now without splitdep, and deptest is not flexible enough.
Introduce a new alpm_find_satisfier which is hopefully more flexible,
this should make implementation of deptest very easy, and also help alpm
tools such as pactree.
