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.

This code as a lot of rough edges, in particular it relies on a well
behaving keyboxd. We need to add code to shutdown the datastream
reader thread in case of errors and to properly get it up again. We
also need to make really sure that both threads run in lockstep so
that the datastream thread is only active while we are sending a
command to the keyboxd.
We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.
And we need to test on Windows.

When searching a key by its name, try to expand the provided name in
case it is a GPG group reference. This GPG group resolution is performed
before the individual keys are verified.
This allows key listing using a GPG group reference. In particular, this
modification fixes the encryption to group support in KDE's Kmail which
is broken since version 18.04.

Those messages are annoying because they might be emitted due to

is missing. No functional regressions are expected because --verbose
should not change anything.
Note that this suppression is only done if no arguments are given to
the command; that is if a listing of the entire keyring is requested.
Thus to see the earnings anyway, a listing of a single or group of
keys can be requested.
