* src/posix-io.c (get_max_fds): use getdents64 instead of getdents.
--
getdents64 was introduced in linux 2.4, so it should be widely
available. some Linux architectures which post-date 2.4 (e.g. arm64)
appear to not have getdents at all, so it's probably better to use the
more modern interface.

* configure.ac (USE_LINUX_GETDENTS): New ac_define. Add option
--disable-linux-getdents.
* src/posix-io.c: Make use of USE_LINUX_GETDENTS.

* src/posix-io.c (get_max_fds): Restore Linux optimization, this time
using open/getdents/close rather than opendir/readdir/closedir.
--
opendir/readdir/closedir may allocate/free memory, and aren't required
to do so in an async-signal-safe way. On the other hand, opening
/proc/self/fd directly and iterating over it using getdents is safe.
(getdents is not strictly speaking documented to be async-signal-safe
because it's not in POSIX. However, the Linux implementation is
essentially just a souped-up read. Python >= 3.2.3 makes the same
assumption.)

* 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).

(get_max_fds) [__linux__]: Try to figure out the highest used fd.

* src/posix-io.c (_gpgme_io_spawn): dup /dev/null also to unsued
stdout.
--
Better be sure that stdout of a spawned process is connected to stdout
so that the process does not run into a write error if it writes to
stdout. AFAICS we always use a connected stdout; thus this is only
for correctness.
* ath.h (ath_self): New prototype. Include <stdint.h>
* ath.c, ath-pth.c, ath-pthread.c (ath_self): New function.
* debug.h: Rewrite most macros to beautify debug output.
(_gpgme_debug_buffer): Remove tagname and tag argument.
(_gpgme_debug_frame_begin, _gpgme_debug_frame_end): New prototypes.
* debug.c: Include <time.h>. Don't include assuan.h.
(frame_nr, FRAME_NR): New thread-specific variable and macro.
(debug_init): Do not initialize assuan. Call _gpgme_debug after
initialization instead using printf directly.
(_gpgme_debug): Do not call debug_init (we now ensure proper
initialization by user). Add timestamp and thread/process ID.
(_gpgme_debug_buffer): Do not take tagname and tag argument.
(_gpgme_debug_frame_begin, _gpgme_debug_frame_end): New functions.
* version.c (gpgme_check_version_internal, gpgme_check_version):
Fix debug string. Do not initialize assuan.
* posix-io.c (get_max_fds): Use 0 not NULL (nicer debug output).
