Add a likely_pkg hint argument to sync_db_read
In most (all?) cases, we will process all files for a given sync database
entry sequentially. The code currently does an _alpm_pkg_find() for every
file in the database, but we had the "current" package readily available.
Shift some local variables around a bit to expose this to sync_db_read() and
use it if the package is the correct one.
On my system, this cuts calls to _alpm_pkg_find() from 20,769 to 10,349
calls during a -Qu operation, and results in a ~30% speedup of the same
operation (0.35 sec -> 0.27 sec). This benefit should be apparent anywhere
we read in the full contents of the sync databases.
