* kbx/backend-sqlite.c (table_definitions): Add column UINO to
userids.
(be_sqlite_local_s): Add fields select_col_uidno and
select_col_subkey.
(run_select_statement): Also select subkey or uidno column.
(be_sqlite_search): Return their values.
(store_into_userid): Store the UIDNO.
* kbx/backend-support.c (be_return_pubkey): Extend PUBKEY_INFO.
--
For an existing database adding the new column to the table userid is
straightforward. However if the original version of the schema used an
integer for the keyid column, that column has likely be renamed. Make
sure that the NOT NULL constraint has also be removed; check the
SQLite documentation on how this can be done.

* kbx/backend-support.c (be_return_pubkey): Add args is_ephemeral and
is_revoked. Adjust callers.
* kbx/backend-sqlite.c: Alter table pubkey to add new columns.
(run_select_statement): Add new column to all selects.
(be_sqlite_search): Return the new flags.
--
For existing test databases the new column can be added with:
alter table pubkey add ephemeral integer not null default 0;
alter table pubkey add revoked integer not null default 0;

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.
