core: Refactor the wait code utilizing the new fdtable.
* src/fdtable.c, src/fdtable.h: Largely extend.
* src/wait-global.c, src/wait-private.c, src/wait-user.c: Remove and
move code to ...
* src/wait.c: here.
(_gpgme_fd_table_init, fd_table_put): Remove.  Do not call them.
(_gpgme_add_io_cb, _gpgme_add_io_cb_user): Change to use the fdtable.
(_gpgme_remove_io_cb, _gpgme_remove_io_cb_user):  Ditto.
(_gpgme_wait_global_event_cb):  Ditto.
(gpgme_wait_ext, _gpgme_wait_on_condition): Ditto.
* src/wait.h (struct io_cb_tag_s): Add fields 'serial' and 'desc'.
Change 'idx' to 'fd'.
(struct fd_table): Remove.
* src/context.h (struct gpgme_context): Remoce 'fdt'.  Rename io_cbs
to user_io_cbs for clarity.
* src/engine-gpgsm.c: Unify trace output.
(start): Pass a description along with the IO handlers.
* src/priv-io.h (struct io_select_fd_s): Rename to io_select_s.
(io_select_t): New.
* src/gpgme.c (_gpgme_cancel_with_err): Replace arg 'ctx' by 'serial'.
(gpgme_cancel): Adjust.
--

This is the second part of a larger refactoring of the wait/event
code.  Does currently only work on Unix and with the private wait
functions (i.e. the async operations don't yet work).

core: Use fully correct command args for gpg --verify.
* src/engine-gpg.c (gpg_verify): Supply --verify for fixed gpg
versions.
--

With 2.1.something we print a warning if no explict command was
given.  Since 2.1.16 this has been fixed to also allow the combination
of --verify and --output.  Thus we now always use "--verify".

core: At debug levels up to 9 print only an ascii dump.
* src/debug.c (_gpgme_debug_buffer): Switch between two output
formats.
--

The new format is much more practical than the bunch of hex digits
followed by just 16 ascii chars.  To get the old behaviour use a debug
level of 10.

core: Link all context objects and add _gpgme_get_ctx.
* src/context.h (struct gpgme_context): Add field 'next_ctx'.
* src/gpgme.c (def_lc_lock): Replace by ...
(context_list_lock): new.
(context_list): New variable.
(gpgme_new): Add new context object to the list.
(gpgme_release): Remove context object from the list.
(_gpgme_get_ctx): New function.
--

To allow mapping a context serial number back to a context object and
to check whether a serialno has still a context object, we need to
link them all together.  We already take a lock to setup the locale
and thus the only overhead is in freeing the context.

Note that the locks are now implicitly done using the systems stdio.

The threadid is now printed with 4 digits in hex and thus without the
angle brackets and the 0x.  However it is still a hex number even if it
may look like an octal number.  The hex letters are uppercase to make
searching in locks easier iff the threadid happens to have a letter in
it.

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;
The --glib option and --thread option which affect the output

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.
