The gpgrt malloc functions are used so that we can easily mix memory

a difference if the gpgme DLL is linked to a different C runtime
than the application.

cJSON has been taken from cjson-code-58.zip. The README file has been
renamed to cJSON.readme and the files have been changed to GNU coding
standards. Because that parser is small enough to be source copied it
does not make sense to treat it as a library and I changed the memory
allocation functions to the usual xmalloc ones. The only external
dependency now is out util.h which declares those functions.
The lowercase cjson_t better fits into our coding style as well as the
new macros. Thanks to Dave Gamble for this nice parser.

opendir/readdir/closedir may allocate/free memory, and aren't required

/proc/self/fd directly and iterating over it using getdents is safe.

essentially just a souped-up read. Python >= 3.2.3 makes the same
assumption.)

Previously, the documentation stated that the expiration time was an
absolute timestamp. However, this value was passed using the
'seconds=N' syntax to GnuPG which specifies the expiration time in
seconds relative to the creation time. Fix the documentation.
Furthermore, the documentation stated that using 0 results in keys
that do not expire. This was communicated to GnuPG by using the
implicit default. However, as of GnuPG 2.1.17, the default was
changed to create keys that expire within a reasonable timespan.
Fix this discrepancy by aligning the behavior with recent GnuPG
versions: 0 means use a reasonable default, and introduce a flag that
can be used to create keys that do not expire. Communicate this
explicitly to GnuPG.

That function is very convenient because it is required a lot with
memory streams. It also documents the intention of the caller better
than gpgme_data_seek with its addition parameters and the need to map
system errors. Thus it does not make sense to make it a first class
citizen again.

The check if address is not allocated would now be more complicated

--
If we have a name and no email but the name can be parsed as
an address we now treat the address as email and remove the name.
This fixes downstream users that rely on email to show email
addresses and don't expilicity handle this case.
E.g. A userid foo@example.com was:
uid->name = "foo@example.com"
uid->email = ""
uid->address = "foo@example.com"
It is now:
uid->name = ""
uid->email = "foo@example.com"
uid->address = "foo@example.com"

gpg(1) documents session key export as useful for key escrow, and is
rightly dubious of that use case. However, session key export is also
useful in other use cases. Two examples from MUA development (where
this functionality would be specifically useful to me right now):
* If the MUA stores a local copy of the session key upon decrypting
the message, it can re-decrypt the message without expensive
asymmetric operations. When rendering a thread with dozens of
encrypted messages, this can represent a significant speedup.
* A user may have expired encryption-capable secret key material,
along with many messages encrypted to that material. If she stores
the session keys for those messages she wants to keep, she can
destroy her secret key material and make any messages she has
deleted completely unrecoverable, even to an attacker who gets her
remaining secret keys in the future.
This patchset makes a two specific implementation decisions that could
have gone in different ways. I welcome feedback on preferred outcomes.
0) session key representation: we currently represent the session key
as an opaque textual string, rather than trying to provide any
sort of in-memory structure. While it wouldn't be hard to parse
the data produced by gpg's --export-session-key, I chose to use
the opaque string rather than lock in a particular data format.
1) API/ABI: i've added a member to gpgme_op_decrypt_result_t. This
has the potential to cause an out-of-bound memory access if
someone uses code compiled against the newer verision, but linked
at runtime against an older version. I've attempted to limit that
risk by documenting that users must verify
gpgme_get_export_session_keys() before accessing this new struct
member -- this means that code expecting this capability will
require the symbol at link-time, and will refuse to link against
older versions.
Another approach to solving this problem would be to avoid
modifying gpgme_op_decrypt_result_t, and to introduce instead a
new function gpgme_op_session_key(), which could be called in the
same places as gpgme_op_decrypt_result(). Depending on the
representation of the session key, this might introduce new
memory-management burdens on the user of the library, and the
session key is certainly part of a decryption result, so it seemed
simpler to go with what i have here.
If anyone has strong preferences that these choices should be solved
in a different way, i'm happy to hear them.
Additionally, I note that i'm also still pretty unclear about how the
"UI Server" fits into this whole ecosystem. In particular, I don't
know whether it's kosher to just add an --export-session-key flag to
the DECRYPT operation without actually having implemented it anywhere,
but i don't see where i would actually implement it either :/
If this patch (or some variant) is adopted, i will supply another
patch that permits offering a session key during decryption (e.g. "gpg
--override-session-key"), but I wanted to get these implementation
choices ironed out first.

On the concern of adding a new field to a structure: It may not be
clearly documented but we don't expect that a user ever allocates such
a structure - those result structure may only be created bu gpgme and
are read-only for the user. Adding a new member constitutes a
compatible ABI change and thus an older SO may not be used by code
compiled with a header for the newer API. Unless someone tinkers with
the build system, this should never happen. We have added new fields
to result structure may times and I can't remember any problems.

* src/gpgme.c (gpgme_set_armor, gpgme_set_textmode,
gpgme_set_offline): Ensure that non-zero values actually set the
appropriate internal bit.
--
The documentation for these functions says things like "disabled if
YES is zero, and enabled otherwise", where YES is an integer.
However, if you pass an even integer, it will be aliased back to 0
because the context member variables are declared as single bits.
This should make the implementation match the documentation.

* src/posix-io.c (_gpgme_io_select): Return EMFILE instead of EBADF.
--
Also EBADF seem more correct, EMFILE (Too man open files) gives
a clearer message to the user that there are somehow too many files
open. The problem can be exhibited by running lots of threads,
We should eventually move to poll but that would be a large change and
so we better fix it with the planned migration of the I/O subsystem to
libgpgrt (currently known as libgpg-error).

gpgme is thread-safe if the conditions mentioned
