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.

Previously, only one weak digest rejection message was shown, of
whichever was the first type encountered. This meant that if "gpg
--weak-digest SHA224" encountered both an MD5 digest and a SHA224
digest, it would only show the user that the MD5 digest was rejected.
In order to let the user know which algorithms were rejected, we
needed to move the "shown" flag into a per-weak-algorithm location.
Given this additional complication, it made no sense to continue to
treat MD5 specially, so it is added as a default weak algorithm in the
same opt.weak_digests data structure as any other.

gpg and gpgv treat signatures made over MD5 as unreliable, unless the
user supplies --allow-weak-digests to gpg. Signatures over any other
digest are considered acceptable.
Despite SHA-1 being a mandatory-to-implement digest algorithm in RFC
4880, the collision-resistance of SHA-1 is weaker than anyone would
like it to be.
Some operators of high-value targets that depend on OpenPGP signatures
may wish to require their signers to use a stronger digest algorithm
than SHA1, even if the OpenPGP ecosystem at large cannot deprecate
SHA1 entirely today.
This changeset adds a new "--weak-digest DIGEST" option for both gpg
and gpgv, which makes it straightforward for anyone to treat any
signature or certification made over the specified digest as
unreliable.
This option can be supplied multiple times if the operator wishes to
deprecate multiple digest algorithms, and will be ignored completely
if the operator supplies --allow-weak-digests (as before).
MD5 is still always considered weak, regardless of any further
--weak-digest options supplied.
