r728: - let libldb_tdb depend on new subsystem LIBTDB

- remove tdb logging helper functions out of LIBTDB subsystem

- build libtdb shared lib with 'make library_libtdb'

the libs are not usable for now,

tridge: please remove the dependecy of CatchSignal() and smb_panic()
        from libtdb
	maybe use function pointers in the TDB_CONTEXT

	then run make library_libtdb
	and then make build/tests/trivial.o
	and then gcc -o trivial -L./bin -ltdb
	and then gcc -o trivial -L./bin -lldb
