Move the deptest code from frontend to backend.

The deptest code (pacman -T) used by makepkg was mostly in the frontend.
There were 2 drawbacks:
1) the public splitdep function returns a pmdepend_t struct, but the
_alpm_dep_free function for freeing it is private. So there was a memleak.
2) there is a helper in the backend (satisfycmp in deps.c) which makes this
function much easier.

So this adds a new public alpm_deptest in libalpm/deps.c, which cleans
pacman_deptest in pacman/deptest.c a lot.
Besides, alpm_splitdep was made private, because the frontend no longer
requires it, and _alpm_dep_free is also private.
Finally the deptest001 pactest was extended.
