* src/init.c (emergency_cleanup_list): New gloabl var.
(_gpgrt_add_emergency_cleanup): New.
(_gpgrt_abort): New. Repalce all calls to abort by this. Also replace
all assert by either log_assert or a stderr output followed by a
_gpgrt_abort.
(run_emergency_cleanup): New.
* src/visibility.c (gpgrt_add_emergency_cleanup): New public API.
(gpgrt_abort): New public API.

Libgcrypt uses its own assert function which makes sure to terminate
the secure memory. This is safe as log as an assert is triggered
internally in Libgcrypt. GnuPG runs emergency cleanup handlers right
before log_fatal etc to tell Libgcrypt to terminate the secure memory.
With the move of the logging function to gpgrt in gnupg 2.3 this did
not anymore. Thus we now provide a mechanism in gpgrt to do right
that. Eventually Libgcrypt can also make use of this.
What this does not handle are calls to abort or failed asserts in
external libraries or in libc. We can't do anything about it in a
library because a library may not setup signal handlers.

* gpgscm/Makefile.am: Remove cruft leftover from GnuPG. Link to the
just build libgpg-error.
* gpgscm/private.h: Include gpgrt.h and provide i18n macros.
(xfree, xtrymalloc, xtrycalloc, xtryrealloc): New macros.
(xmalloc, xstrdup): New inline functions.
* gpgscm/main.c: Remove inclusion of gcrypt.h and gpg-error.h. Remove
all other gnupg specific headers.
(opts, parse_arguments): Temporary comment out.
(main): Adjust for use with gpgrt. Temporary comment out some stuff.
* gpgscm/ffi-private.h: Include local gpgrt.h instead of gpg-error.h.
* gpgscm/ffi.h: Ditto.
* gpgscm/ffi.c: Remove gpg-error.h and headers from GnuPG.
(do_getenv): Use gpgrt_getenv.
(do_setenv): Use gpgrt_setenv.
(do_mkdtemp): Temporary return an error.
(unlink_recursively): Use gpgrt_bsprintf.
(do_getcwd): Use gpgrt_getcwd.
(do_mkdir): Use gpgrt_mkdir.
(do_get_isotime): Temporary return an error.
(do_get_time): Directly use time().

Note that this does not yet compile because the spawn functions from
GnuPG are missing. There are two other problems as well:
- We don't have GnuPG's isotime fucntions. We need to see whether we
want to support them in gpgrt. That might be useful in libksba.
- gpgrt_mkdtemp does not work. We do not want to link to Libgcrypt,
which is the way mkdtemp was written for GnuPG. We should get a
more straight implementation.

All changes to TinySCHEME were done by employees of g10 Code GmbH and
some minor things by a contractor.

Note that we used
git filter-branch --subdirectory-filter tests/gpgscm
in gnupg master to filter out the gpgscm part. This commit merely
moves these files to a subdirectory which will be used in libgpg-error
for gpgscm.
