json: Put signature info before data output
* src/gpgme-json.c (op_decrypt): Move info before data.

This should enable it to first parse signatures before

core, w32: Add w64 handling for regkeys
* 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.

core: Always fail if an OpenPG message is not integrity protected.
* 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.

core: Do not modify args for ignored failures
* 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.

Before the insertion of the compliance status checking the break in
the default clause was used by the STATUS_PLAINTEXT code.  That got
lost.  I don't see any actual harm due to different values currently
in use for the compliance status.

The c++ bindings and others assumed that r_key is set to NULL
