(be_release_request): Ditto.
(be_find_request_part): Ditto.
(is_x509_blob): Rename to ...
(be_is_x509_blob): this and make global.
* kbx/frontend.c (kbxd_set_database): Detect ".db" suffix and use that
for SQLite.
(kbxd_search): Support SQLite
(kbxd_store): Ditto.
(kbxd_delete): Ditto.
* kbx/frontend.h (kbxd_store_modes): Move to ...
* kbx/keyboxd.h (enum kbxd_store_modes): here.

Take care: This is not finished and in particular filling the database
takes quite long.

kbx: Change keyboxd to work only with one database.
* kbx/frontend.c (the_database): New var.
(db_desc_t): Remove.
(kbxd_add_resource): Renamed to ...
(kbxd_set_database): this.  Simplify.
(kbxd_search): Change to use only one database.
(kbxd_store): Ditto.
(kbxd_delete): Ditto.

The original implementation was way to complicated and would have only
brought back the problems deciding which database to use for each key.
The new scheme used one configured database and only that.  That
database needs to be set right at the start.

It turned out that using the hash of the entire blob was not helpful.
Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint
of the blob.  In case this is a v5 OpenPGP key a left truncated
version of the SHA-256 hash is used; in all other cases the full SHA-1
hash.  Using a SHA-256 hash does not make sense because v4 keys are
and will for some time be the majority of keys and thus padding them
with zeroes won't make any difference.  Even if fingerprint collisions
can eventually be created we will assume that the keys are bogus and
that it does not make sense to store its twin also in our key storage.
We can also easily extend the update code to detect a collision and
reject the update.
