gpg: Fix trustdb updates without lock held.
* g10/tdbio.c (is_locked): Turn into a counter.
(take_write_lock, release_write_lock): Implement recursive locks.
--
On trustdb creation we have this call sequence:
init_trustdb -> takes lock
tdbio_set_dbname
create_version_record
tdbio_write_record
put_record_into_cache -> takes lock
put_record_into_cache -> releases lock
init_trustdb -> releases lock
The second take lock does noting but the first release lock has
already released the lock and the second release lock is a thus a NOP.
This is likely the cause for the corrupted trustdb as reported in
