core: Fix segv in genkey when no endtag is provided.
* src/genkey.c (get_key_parameter): Provide a fallback ENDTAG.
--

It would actually be more correct to return an error in this case but
it is possible tha there are users who did not provide an endtag and
out of luck they also didn't trigger a segv.

--

We do not want to expose details of the protocol's key generation and
thus the subkey-algo does not make sense.  Right now we support only
the default and future-default algorithms.  A user can configure them
anyway using new-default-key-algo in gpg.conf.  Eventually we may
officially support a more flexible way of creating special structured
OpenPGP keys but right now that is not part of the API.

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.

Due to the funny quick-gen-key interface generating a key

without a subkey.

the semantics of createkey by adding default subkey_algo handling.

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.

(op_keylist, hlp_keylist, hlp_export, op_export): Update accordingly.

--
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.
