* Updated the decryption example code in the HOWTO and the
corresponding decrypt-file.py script to gracefully handle a
decryption failure. This error will always be triggered when GPGME
is used to try to decrypt an old, MDC-less encrypted message or
file.
* src/w32-util.c (_gpgme_get_gpg_path): Use new defines.
(GNUPG_REGKEY_2): x64 aware regkey as used by GnuPG in Gpg4win 2.x
(GNUPG_REGKEY_3): x64 aware regkey as used by GnuPG in Gpg4win 3.x
(_gpgme_get_gpgconf_path): Use new regkeys. Add another fallback.
--
This should fix more "unsupported protocol" issues if Gpg4win /
GnuPG is installed in a non standard path on 64bit systems.
The regkey handling is similar to that of gpgex and gpgol.

* src/decrypt.c (struct op_data_t): Add field not_integrity_protected.
(parse_decryption_info): Set this. Also rename mode to aead_algo for
clarity.
(_gpgme_decrypt_status_handler): Force failure in case of a missing
MDC.
--
This extra check makes sure that a missing or stripped MDC in
- gpg < 2.1
- or gpg 2.2 with an old cipher algorithm
will lead to a decryption failure. gpg 2.3 will always fail in this
case. Implementing this check here and not backporting the 2.3 change
to 2.2 has the benefit that all GPGME using applications are protected
but scripts relying on rfc2440 (i.e. without MDC) will only break when
migrating to 2.3.
Note that S/MIME has no integrity protection mechanism but gpgsm
neither emits a DECRYPTION_INFO status line, so an error will not be
triggered. If in the future gpgsm supports authenticated encryption
it may issue a DECRYPTION_INFO line to force a failure here but it
will in that case also emit a DECRYPTION_FAILED anyway.

* Changed the expiration date for the generated test key to NYE this
century, rather than the NYE this millennium as originally suggested
in job #3815.
* This covers the lifetimes of current users (except, maybe, some very
healthy millennials) as well as the 32-bit clock end date in 2038;
without falling foul of OpenPGP's 2106 expiration.

* src/op-support.c (_gpgme_parse_failure): Ignore gpg-exit failures
before modifying args.
--
For op_decrypt_verify the status handler for both decrypt and
verify would parse the failure when the first parser ignored
the failure. This resulted in an ERR_INV_ENGINE as the first
call to parse_failure modified the args.

* src/verify.c (_gpgme_verify_status_handler): Remove debug output.
--
Actually this is a real bug because it uses a debug function available
only in the new libgpg-error versions. Time to call Jenkins back from

* tests/gpg/t-verify.c (check_result): Tweak for gnupg < 2.2.7.
--
The not yet releases 2.2.7-beta may print a full fingerprint in the
ERRSIG status. This is compliant with the dscription but the new
t-verify test case did not took in account that older GnuPG versions
print only a keyid.

* src/verify.c (_gpgme_verify_status_handler): Insert missing break.

Before the insertion of the compliance status checking the break in

lost. I don't see any actual harm due to different values currently
in use for the compliance status.

* lang/python/setup.py.in: Copy gpgme.h instead of parsing it.
--
The python bindings tried to parse deprecated functions
out of gpgme.h. This fails for the current gpgme.h in
that it removes an entire field in the key sig struct (_obsolete_class).
Hence, the fields were off by an int and the bindings accessed struct
members via the wrong offset. That caused python program to crash.
At least on 32bit platforms, the crash can be easily triggered by
accessing key.uids[0].signatures. On 64bit platforms the compiler
probably aligns the struct so that the missing 4 bytes are not noticed.
With this change, the python bindings will expose all functions
that gpgme exposes, including the deprecated ones.
Credits go to Justus Winter for debugging and identying the issue.
