Want gvdb support for lookup with precalculated hash

Submitted by Alexander Larsson Link to original bug (#667991)
Description
The way GResources uses gvdb we do multiple lookups of the same string in multiple tables. With the current code this does a hash calculation of the string each time. It would be nicer if we could precalculate it with g_str_hash() and pass the hash value to the lookup function.
