This change does away with encrypting and decrypting the cached PIN in
the agent. There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent. This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

with XXXX being 20190230T000000 -> target cert too young
with XXXX being 20190330T000000 -> okay
with XXXX being 20190830T000000 -> okay, using the long term cert
with XXXX being 20220330T000000 -> target cert expired
The --disabled-crl-checks option is required because in our a simple
test setting dirmngr does not know about the faked time.

--
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.

I once replaced all JNLIB macros by GPGRT macros. However, I missed

instead of the correct
GPGRT_HAVE_PRAGMA_GCC_PUSH
Now after fixing this it turned out that no-strict-overflow is not
anymore supported as oprimize pragma and thus I replaced that too
according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58454 .

fixes this bug

There was no way to specify an LDAPS server in
dirmngr_ldapserver.socnf or with gpgsm's --keyserver option. This
patch fixes this. Eventually we should allow to replace host and port
by a partial URI in the same way ldap_initialize does it. For backward
compatibility we do not yet do that.
Although the dirmngr code accepts an URL (eg. taken from a
certificate), I can't see how the scheme was ever used. Thus the
patch also detects an ldaps scheme and uses this. That part has not
been tested, though.
