Read pkgcache into hash

Read the package information for sync/local databases into a pmpkghash_t
structure.

Provide a alpm_db_get_pkgcache_list() method that returns the list from
the hash object.  Most usages of alpm_db_get_pkgcache are converted to
this at this stage for ease of implementation.  Review whether these are
better accessing the hash table directly at a later stage.
