This provides a way to get the extended key-edit interface without
breaking bad state machines that rely on the current command flow.

A use case for this is to enable multiple local signatures, which
can be used together with annotations for:

I don't know how often I wrote:

And for the context it is good practice to use a unique ptr
so the API should make it easy.

--
This enables users of GPGME to get more verbose information
from gpg which can assist users in figuring out a problem
that was before hidden behind a generalized error like
"Decryption Failed".

For GPGSM it is not yet available as it is problematic to
get it properly in server mode and GPGSM already had the
original audit log mechanism in place.

GPGME_AUDITLOG_DEFAULT was added for a more explicit
documentation.

* 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.

* NEWS: Document new interfaces.
* doc/gpgme.texi: Document new interfaces.
* src/gpgme.h.in (GPGME_DELETE_ALLOW_SECRET, GPGME_DELETE_FORCE,
gpgme_op_delete_ext_start, gpgme_op_delete_ext): New.
* src/delete.c (delete_start): Change allow_secret argument to flags.
(gpgme_op_delete_ext, gpgme_op_delete_ext_start): New functions.
* src/engine-backend.h (delete): Change allow_secret argument to flags.

python: Improve error handling.
* NEWS: Update.
* lang/python/src/core.py (Context.__read__): New helper function.
(Context.encrypt): Attach partial results to exceptions.
(Context.decrypt): Likewise.
(Context.sign): Likewise.
(Context.verify): Likewise.
* lang/python/src/errors.py (GpgError): Move the core of GPGMEError to
this class, add a nicer interface for it.  This makes the errors
thrown by this library more uniform, and allows us to track the
underlying error in synthesized high-level errors.
(GPGMEError): Simplify.
(...): Make sure to call the parent classes' constructor in all other
classes.

Attach partial results to errors.  Some operations return results even
though they signal an error.  Of course this information must be taken
with a grain of salt.  But often, this information is useful for
diagnostic uses or to give the user feedback.  Since the normal
control flow is disrupted by the exception, the callee can no longer
return results, hence we attach them to the exception objects.
