This patch fixes several database-related problems.
dbm_open has been moved into gdbm_compat, so we check for that and include it.
ndbm.h is located in /usr/include/gdbm on Gentoo, so we only check
there, given that we don't support normal dbm installations, and we
patch database.c as well. Not portable beyond Gentoo, but will work
for us.
The checks for Berkeley DB only took into account up to version
3. Added checks to deal with several versions 4 as well.
