Instead of doing GMP by hand, use the Gnulib libgmp module.
* .gitignore: Add lib/gmp.h.
* admin/merge-gnulib (GNULIB_MODULES): Add libgmp.

LIB_GMP, so all uses changed. All uses of GMP_OBJ removed.

New files, copied from Gnulib.
* src/bignum.h, test/data/emacs-module/mod-test.c:
Include gmp.h unconditionally.
* src/mini-gmp-emacs.c, src/mini-gmp.c, src/mini-gmp.h:
Remove. This moves these files from src to lib, and
updates them to the current GMP version.
* test/Makefile.in (GMP_H): New macro.
($(test_module)): Use it to decide whether to compile
mini-gmp-gnulib.c too.
These changes let the code compile and produce a valid DLL, but the
test hangs. It looks like the hang is in Fdelete_process, when it
closes one of the descriptors of the pipe process.
In addition, this use of the pipe process cannot currently work
on MS-Windows, since make-pipe-process doesn't set up the reader
thread to read from the Emacs's side of the pipe, so the select
emulation doesn't know there's stuff to read from that pipe.
* test/data/emacs-module/mod-test.c [WINDOWSNT]: Include
windows.h.
(ALIGN_STACK) [!__x86_64__]: Define for 32-bit builds.
(sleep_for_half_second): New function.
(write_to_pipe): Declare return type differently for WINDOWSNT.
Call sleep_for_half_second.

for pthread_create.
(invalid_finalizer): Replace non_ASCII character in a comment.
* test/src/emacs-module-tests.el (module/async-pipe): Skip on
MS-Windows, as the test fails and then hangs.
A common complaint about the module API is that modules can't
communicate asynchronously with Emacs. While it isn't possible to
call arbitrary Emacs functions asynchronously, writing to a pipe
should always be fine and is a pretty low-hanging fruit.
This patch implements a function that adapts an existing pipe
process. That way, users can use familiar tools like process filters
or 'accept-process-output'.

This is especially useful in cases where modules only use a single
entry point and use the data to dispatch to the actual function. Such
a design is common for languages such as Go and C++.

than 'unsigned long'.

check also mod-test-emacs with ".exe" appended, before
skipping the tests.
As described in the new comment added to emacs-module.c, using GMP
directly in the module interface has significant downsides: it couples
the module interface directly to the implementation and requires
module authors to link their module against the same GMP library as
Emacs itself, which is often difficult and an unnecessary burden. By
picking a representation for the magnitude that often matches the one
used by GMP, we can avoid overhead when converting from and to GMP in
most cases.
Loading the test module in test/data/emacs-module and evaluating
(dotimes (_ 10000)
(mod-test-double (* 2 most-negative-fixnum)))
under Callgrind shows that on my (GNU/Linux) machine Emacs only spends
10% of the CPU time of mod-test-double in mpz_import and mpz_export
combined, even though that function does little else. (By contrast,
30% is spent in allocate_pseudovector.)
* src/emacs-module.h.in: Don't check EMACS_MODULE_GMP. Don't include
gmp.h. Remove emacs_mpz structure. Instead, define type alias
emacs_limb_t and macro EMACS_LIMB_MAX.
* src/module-env-27.h: Change interface of extract_big_integer and
make_big_integer to take a sign-magnitude representation instead of
mpz_t.
* src/emacs-module.c: Don't check EMACS_MODULE_GMP or
EMACS_MODULE_HAVE_MPZ_T. Add a comment about the chosen
implementation.
(module_extract_big_integer, module_make_big_integer): Reimplement
without using mpz_t in the interface.
* doc/lispref/internals.texi (Module Values): Adapt function
documentation and example. Stop mentioning GMP and EMACS_MODULE_GMP.
* test/data/emacs-module/mod-test.c: Don't define EMACS_MODULE_GMP or
EMACS_MODULE_HAVE_MPZ_T.
(memory_full, extract_big_integer, make_big_integer): New helper
functions, identical to example in the Info documentation.
(Fmod_test_nanoseconds, Fmod_test_double): Adapt to new interface.
* test/data/emacs-module/mod-test.c (NDEBUG): Undef, to prevent
GCC from complaining “error: unused variable ‘dummy’” and failing
to build the test, if --enable-gcc-warnings.
* test/data/emacs-module/mod-test.c (Fmod_test_nanoseconds)
[__MINGW32__]: Use _Static_assert, not static_assert, as the
latter is not available in mingw.org's MinGW's assert.h.
Add support for a new preprocessor macro EMACS_MODULE_HAVE_MPZ_T to
emacs-module.h. If this macro is defined, assume that mpz_t is
already defined and don’t include gmp.h.
Don’t document the new macro for now, as it’s unclear whether we want
to support this in modules outside the Emacs tree.
* src/emacs-module.h.in: Allow user to prevent inclusion of gmp.h.
* src/emacs-module.c: Use mini-gmp if GMP is unavailable. Don’t
include gmp.h.

* test/Makefile.in (GMP_LIB, GMP_OBJ): New variables.
($(test_module)): Use them.
* test/data/emacs-module/mod-test.c: Use mini-gmp if GMP is unavailable.

truncation is towards negative infinity.

function.

Time values are a fundamental data type, and such conversions are hard
to implement within modules because of the various forms of time
values in Emacs Lisp. Adding dedicated conversion functions can
significantly simplify module code dealing with times.
This approach uses nanosecond precision. While Emacs in theory has
support for higher-precision time values, in practice most languages
and standards, such as POSIX, C, Java, and Go, have settled on
nanosecond-precision integers to represent time.
* src/emacs-module.h.in: Add header for struct timespec.
* src/module-env-27.h: Add module functions for time conversion.
* src/emacs-module.c (module_extract_time, module_make_time): New
functions.
(initialize_environment): Use them.
* test/data/emacs-module/mod-test.c (Fmod_test_add_nanosecond): New
test function.
(emacs_module_init): Define it.
* test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid)
(mod-test-add-nanosecond/nil, mod-test-add-nanosecond/invalid): New
unit tests.
* doc/lispref/internals.texi (Module Values): Document time
conversion functions.
pending_signals is often set if no quit is pending. This results in
bugs in module code if the module returns but no quit is actually
pending.
As a better alternative, add a new process_input environment function
for Emacs 27. That function processes signals (like maybe_quit).
* configure.ac: Add module snippet for Emacs 27.
* src/module-env-27.h: New file.
* src/emacs-module.h.in: Add process_input function to environment
interface.
* src/emacs-module.c (module_should_quit): Use QUITP macro to check
whether the caller should quit.
(module_process_input): New function.
(initialize_environment): Use it.
* src/eval.c: Remove obsolete comment.
* test/data/emacs-module/mod-test.c (signal_wrong_type_argument)
(signal_errno): New helper functions.
(Fmod_test_sleep_until): New test module function.
* test/src/emacs-module-tests.el (mod-test-sleep-until): New unit
test.

1-indexing for all ordered lists, use <ol> if given.
