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.

This adds a caching backend to the keyboxd. This tries to accommodate
for duplicate use of fingerprints and thus be correct in case a
fingerprint is used in several keys. It also turned out that we need
to have a unique identifier (UBID) to identify a keyblock or X.509
certificate. In particular with an OpenPGP keyblob we can't easily
use the primary fingerprint as an identifier because that fingerprint
may also be used as subkey in another key. Thus using a hash of the
entire keyblock is a better identifier to be used to address a
keyblock for restarting a search or for identifying the keyblock to be
updated. Note that this new UBID is not a permanent identifier
because it changes with all keyblock update; it should be viewed as a
handle to the keyblock or X509 cert.
* kbx/keybox-search.c (keybox_search): We need to seek to the last
position in all cases not just when doing a NEXT.

This is because search from the beginning needs a keybox_search_reset.

These search modes were added over time and there has until recently

finally went over all places and allowed the generic fingerprint mode
along with a given length of the fingerprint at all places.
Consequently the other modes can now be removed.

The keybox code doesn't work directly with keyblocks. As such, the
matched user packet is not readily available to pass to
DESC[n].SKIPFNC. But, we do know the index of the user id packet that
matched. Thus, pass that instead. If the skip function needs the

Import and key listing does now work with the keybox format. It is

Increasing the maximum allowed length for a keyblock was required due
to a 700k keyblock which inhibited kbxutil to list the file.
kbxutil's option name --import-openpgp is not quite appropriate
because it only creates KBX blobs from OpenPGP data.
