Move alpm_splitdep usage to db_read
Holy inefficient batman! For a pacman -Qt operation (when we are using
compute_requiredby and not database entries), splitdep was being called ~1.3
million times on my local database. By splitting when we read the DB, we
drop this number to around 1700 and save a LOT of time in doing so (a 5x
increase in pacman -Qt speed here).
Note that the depends alpm_list_t in the package struct is no longer a
string list, but a list of pmdepent_t objects.
