r16774: This patch modifies the tdb API to allow the logging function to be used

as part of ldb.

This allows tdb failures to be passed all the way up to Samba's DEBUG
system, which allowed easier debugging.

Unfortunately I had to extend the tdb API, as the logging function
didn't have a context pointer.

I've worked over the 'debug levels' in TDB.  Most of them were 0,
which didn't seem right, as some were trace-like messages.  We didn't
see any of these previously, except when accessing TDB directly.
