Modified:

   trunk/mythtv/libs/libmythdb/mythdb.cpp

Log:

Optimize the settings cache for the cache hot case.

This change saves a couple of qhash lookups in the cache hot case.

It also allows caching of default values when there is no entry in
the settings table for that item. Otherwise we keep trying the DB
for non existent settings.
