split format and with that all the caching. Use the dbs struct
directly. Move global vars for batch update into CTRL. Change
calling conventions of some function to take CTRL or DBS pointers
instead of the former low-level database pointer.
--
The split database format might have been nice for use with Unison but
it bypasses the concept of a relational database by doing parts of
this itself and also risking deadlocks. Working with the Tofu
database for debugging or experiments is also not possible with parts
of the database logic implemented in gpg.
The Tofu support is quite new and we can assume that it is not in real
use now. Thus we better remove that now so that we do not need to
maintain it for all future.

With my test keybox I see a speedup of 10 times (33s to 3.1s). The
reason for this was the extra key lookup which I hacked in at some
point to make the extraction of a keyid correct also for non v4 keys.
However our caller already has the public key and thus can easily pass
it to get_trust along with the fingerprint.

The most recent message was verified 3 days, 13 hours ago.
(key: 8061 5870 F5BA D690 3336 [...] 1E42 B367, policy: auto)
