core: Fix parsing of userid sigs after a subpkg
* src/keylist.c (keylist_colon_handler): Do not clear
out the tmp_uid when a subpacket line is encountered.

--
When the uid is cleared no more signatures following
the subpacket are parsed, so we now no longer clear
it when a subpacket is encountered.

This provides a way to get the extended key-edit interface without
breaking bad state machines that rely on the current command flow.

A use case for this is to enable multiple local signatures, which
can be used together with annotations for:

core: Fix arg counting in enginge-gpg
* src/engine-gpg.c (build_argv): Properly check for all
arguments and allocate memory for them.

--
This fixes a potential buffer overflow which could be created
by using unusual and partially contradictory options.
Like offline and auto-key-locate together while
using ignore-mdc-error.
As the list of arguments should not be user controlled the
impact of this is very low.

To ensure that this does not happen in the future an
assert is also added with this patch.

--

The new format is much more practical than the bunch of hex digits

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.

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.
