* src/gpgme.h.in (GPGME_DATA_ENCODING_MIME): New.
* src/data.c (gpgme_data_set_encoding): Adjust check.
* src/engine-gpg.c (have_gpg_version): New.
(gpg_encrypt, gpg_encrypt_sign): Pass flag '--mimemode'.
(gpg_sign): Ditto.

* lang/cpp/src/data.cpp (encoding, setEncoding): Support MimeEncoding.
* src/gpgme-tool.c (server_data_encoding): Add flag --mime.
--
This feature allows an application to declare that the encrypted or
signed data is a valid MIME part.
What is missing is a way to return that information to the application
after decryption/verification. This can be done by setting the
encoding of the output data object; however this requires some
internal additions to our processing model.

* lang/cpp/src/context.cpp (supported_features2): Add
BinaryAndFineGrainedIdentify
* lang/cpp/src/global.h (Feature2): ditto.
--
This is mostly for compatible code with KF5::Gpgmepp where there
is no hard requirement against gpgme 1.7. With 1.7 a version
check would also suffice.
* lang/qt/src/Makefile.am (camelcase_headers): New. Create and install
CamelCase headers.
--
For Qt Libraries it is a common pattern that headers are installed
additionally under their Namespace / Class Name so that automated
inclusion works once a class is used in code. This was also
done for QGpgME headers when they lived in Libkleo so this increases
compatibility.
* lang/cpp/src/gpgmepp_version.h.in,
lang/qt/src/qgpgme_version.h.in: New. Version information.
* lang/qt/src/Makefile.am, lang/cpp/src/Makefile.am: Add them.
* configure.ac: Configure them.
--
The version headers are common practice in KDE Frameworks and
were installed for KF5Gpgmepp and Libkleo respectively.
* lang/python/gpgme.i (gpgme_data_t): Rework so that it works without
access to the definition of 'struct gpgme_data'.
* lang/python/helpers.c (object_to_gpgme_data_t): Add assertion.

Even with the wait this test could fail and anyway the delay
was not nice. So we remove the wait hack and just wait for
the bug (2405) to be fixed in GnuPG or GpgME core.

* lang/qt/tests/Makefile.am (AM_CPPFLAGS): Include cpp before
gpgme src directory.
--
This fixes a problem where context.h would be picked up from gpgme/src
instead of including the context.h from gpgme++.
* lang/qt/src/threadedjobmixin.h: Revert using full path
for context.h
--
This reverts commit 47bfbc9026 as
it causes problems depending on the include path. The proper
fix will be to ensure that cpp/src is included before gpgme/src.
* lang/qt/src/threadedjobmixin.h: When building qgpgme look for
context.h in the full cpp subdirectory.
--
Gpgme core also contains a context.h that can lead to confusion
otherwise.
* src/lang/qt/tests/t-tofuinfo.cpp(testTofuSignCount): New.
(initTestCase): Set gpg-agent loopback pinentry config.
(signAndVerify): Helper for tofuTestSignCount.

Also needs the wait code because of GnuPG-Bug-Id: 2405

* lang/qt/tests/Makefile.am: Update accordingly.
--
The test currently contains a workaround for GnuPG-Bug-Id 2405
* lang/cpp/src/editinteractor.cpp (status_to_error): No error
for KEYEXPIRED.
--
As keyexpired status is sent even if a subkey is expired
we can not treat it as a global error.
Results returned by the GPGME are fragile, i.e. they are only valid
until the next operation is performed in the context.
We cannot arbitrarily constrain the lifetime of Python objects, we
