Detect incompletely regenerated databases.

This saves the timestamp in the database instead of relying on the .db
file's mtime (which would be newer than source).  There are better ways to
do this, but I did the simplest one for now, since aborted builds result in
very "fun" bugs, and we badly want this fixed for 0.8.

Also, there were nice race conditions, multiple rw opens, and so on.

The whole database system needs to be rewritten quite badly, it's a mess of
layers upon layers, remnants of DBM that was used in the dark past.

This is only the db, dsc files suffer from the same problems, and the fix
there will be a lot more complex :(
