The overlapping code in _alpm_pkghash_add() and _alpm_pkghash_add_sorted()
are now in a new static function pkghash_add_pkg(). This function has a
third flag parameter which determines whether the package should be added in
sorted order.

Rather than potentially move every item to the next NULL, attempt to move at
most one item at a time by iterating backwards from the NULL location in the
hash array. If we move an item, we repeat the process on the now shorter
"chain" until no more items need moving.

Fully removes a package from the hash. Also unify prototype with
removal from an alpm_list_t, fixing issues when removing a package
from the pkgcache.

While probably still not optimal in terms of everyday usage in
pacman, this reduces the absolute size increase to "more reasonable"
levels. For databases greater than 5000 in size, the minimum size
increase is used which is still on the order of a 10% increase.

Check that the requested size of a pkghash is not beyond the maximum
prime. Also check for successful creation of a new hash before
rehashing.

This allows us to get through the rehash required by smoke001 and pass
all pactests. It is by no means the best or most efficient
implementation but it does do the job.
