core: Fully implement the inquire callback for assuan_transact
* src/engine-assuan.c (inquire_cb): Implement returning data.

* tests/opassuan/t-command.c (inq_cb): Send some test data.
--

The old code only allowed to send an empty response which was good
enough for scdaemon's KNOWNCARDP inquire but not to send actual data.
A quick test using a test smartcard might be

 ./t-command 'scd setattr --inquire PRIVATE-DO-1'

and then reading the data back using

  gpg-connect-agent 'scd getattr PRIVATE-DO-1' /bye

f66f856c89 core: Add error handling to setexpire
* src/genkey.c (setexpire, gpgme_op_setexpire_start,
gpgme_op_setexpire): Move to ...
* src/setexpire.c: New.
* src/Makefile.am (main_sources): Add that file.
* src/context.h (ctx_op_data_id_t): Add OPDATA_SETEXPIRE.

* lang/qt/tests/t-various.cpp (testSetExpire): Test error handling.
--

Errors (and failures) emitted via status-fd need to be handled
explicitly, i.e. we need to provide an appropriate status handler with
corresponding op_data_t. Additionally, we need to set a passphrase
command handler if a passphrase callback is set in the context, e.g.
during tests.

This extends GPGME to support the --quick-set-expire command
added by GnuPG 2.1.22. This allows changing subkeys expiry
date without going through the editinteractor interface.

This never worked in reality because the required feature has been
removed from GnuPG version 1.3.2 soon after introduction of this
feature in gpgme - 17 years ago.  It was anyway marked as
experimental.  We keep the API and ABI, though.

Since GnuPG 2.2.19 the keygrip was not anymore send if only
--with-secret was used in a public key listing.  Given that
--with-secret requires computation of the keygrip anyway, there is no
point in not requesting the keyrip in this case.

The uidhash value is part of gpg's output since the year 2005.  This
now adds support to gpgme.  The application for uidhash is to select
a user id in an edit interactor: Instead of giving the number of the
user id, the uidhash value can be be used to avoid tracking the user
id numbers.

Without this change, the signature verification would fail.  This

gcc 8 enables a couple of new warnings.  Some of them are useless for
us.  In particular:

  util.h:42:26: warning: division 'sizeof (char *) / sizeof (char)'
  does not compute the number of array elements [-Wsizeof-pointer-div]
  #define DIM(v) (sizeof(v)/sizeof((v)[0])) ^

  trustlist.c:101:22: note:
  in expansion of macro 'DIM' if (strlen (p) == DIM(item->keyid) - 1)

Which is a real standard way to use DIM, here the right hand side is
equivalent to sizeof but nevertheless it is correct.  Yes sir, we know
C.

The format string warnings I have seen were assuming that the time
structure returns valued out of scope - but if the system is that
broken, the s_n_printf catches this.

Some usages of gpgme-config is not compatible to pkg-config style;

gpgme-config's embedding information for gpg-error and libassuan at
the build time of gpgme is considered inflexible than pkg-config
style.  It is now handled by dependency of gpgme.pc (Requires field).

To use gpgme.pc, newer libgpg-error (>= 1.33) and libassuan (>= 2.5.3)
are required, which provide gpg-error.pc and libassuan.pc respectively.

2375959180 estreams revised
* Egon Spengler was right, crossing the streams is bad.
* Restored both src/gpgme.def and src/libgpgme.vers to use the
  estreams symbols without the leading underscore.
* The new_from_estream() function added to lang/python/src/core.py and
  set to alias the new_from_stream() function remains.
* Opted for the solution favouring Linux onthree main grounds:
  1. Andre reported major problems with Windows as well, so the number
     of potentially affected systems would vastly increase.
  2. All the BSDs and OS X have spent far more time and development
     work in order to accommodate the eccentricities of both Microsoft
     and the GNU Project (ref. GCC), so they're more likely to be able
     to cope with doing so again than the other way around.
  3. If I really have to I can write a custom installer for OS X to
     try this and, if it fails, to then patch the two symbol entries and
     recompile from scratch.  That said, I may not have to since it
     actually behaved during the most recent tests for this
     commit; into ten separate CPython installations and all five
     supported versions (standard source installs and OS X Framework
     installs for each version).

json: Do not put FILE_NAME into the verify result.
* src/gpgme-json.c (verify_result_to_json): Remove "file_name".
--

Having the file name in the verify result may lead developers to
assume that the file name is covered by the signature.  This is not
the case and can easily be checked by hex-editing a signed message.
We better don't output it at all.

The same is true for the is_mime flag but that is anyway only an
advisory and I can't see damage from a faulty one.

Note that we keep file_name in gpgme's output for ABI stability and
because some tools want to display meta information even if they are
subject to tampering.  This is similar to the non-encrypted subject in
mails.

This is a best effort feature to not output plaintext after a
decryption failure (e.g. due to no or broken authenticated
encryption).  It always work when using a memory object and reading it
after the decryption but it can't work reliable when the user is
reading from the data object while the decryption process is still
running.

This is quite a large change because the data objects and the context
objects are allowed to be owned by different threads.  Thus a
synchronization is needed and we do this with a global table of all
data objects to which the context objects can do soft-linking via a
unique data object serial number.

--
To include handling for json properties e.g. in a keylist in
the chunk mechanism the mechanism is now more general.

If the chunksize property is provided the response will
always look exactly like a "getmore" response. E.g.

e.g.:
{
    "op": "keylist",
    "chunksize": 64
}
Results in:
{
   "more": true,
   "base64": true,
   "response": "ewoJImtleXMiOglbewoJCQkicmV2b2tlZCI6"
}

For simplicity this is even true if the chunksize is larger
then the response.

The client has to combine all "response" chunks and base64
decode them to get valid json.

The complete response (including json) is never larger then
the chunksize but might be smaller. Except for interactive
use due to additional format characters.

This pattern of gpgme_type to json object conversion
is much cleaner then the error returning "add to object"
functions.

json: Implement keylist
* src/gpgme-json.c (xjson_AddStringToObject0)
(xjson_AddItemToObject): New helpers.
(sig_notation_to_json, key_sig_to_json, tofu_to_json)
(uid_to_json, subkey_to_json, key_to_json): New
GPGME to JSON functions.
(op_keylist): New.
(process_request): Add op_keylist.

--
The conversion from GPGME data structures to
JSON follow the same pattern for the keylist
functions using the xjson wrappers instead
of error checking every cJSON call.

For large keylists the keylist command also
needs a data / getmore handling somehow.
