separate local from sync dbs on filesystem

Introduce two new methods into the API - alpm_db_register_sync and
alpm_db_register_local, which replace the functionality of
alpm_db_register. db_register_local always returns the local DB, and
db_register_sync will always try to register a sync DB. This conceptually
separates the local DB from sync DBs in the code. Also updated the pacman
frontend to use the new functions. In addition, this changes the location
of all sync DBs in the filesystem from $DBPATH/$REPO to $DBPATH/sync/$REPO,
This removes the silly limitation that a sync DB couldn't be named 'local',
along with structurally separating sync DBs and the local DB in the
filesystem.
