* modules/dynarray (configure.ac): Invoke AC_PROG_MKDIR_P.

malloc/dynarray.gl.h and malloc/dynarray-skeleton.gl.h.
* modules/scratch_buffer (configure.ac): Invoke AC_PROG_MKDIR_P.

* lib/dynarray.h: Don't include <libc-config.h>. Define _GL_LIKELY,
_GL_UNLIKELY. Include malloc/dynarray.gl.h instead of malloc/dynarray.h.
Include malloc/dynarray-skeleton.gl.h instead of
malloc/dynarray-skeleton.c.
* modules/dynarray (Depends-on): Add builtin-expect.
(Makefile.am): Arrange to create malloc/dynarray.gl.h from
malloc/dynarray.h and malloc/dynarray-skeleton.gl.h from
malloc/dynarray-skeleton.c.

* lib/dynarray.h: Document the exported API. Comments taken from
lib/malloc/dynarray-skeleton.c and lib/malloc/dynarray.h.
Distinguish an internal include from an include for instantiation.
In the latter case, include <libc-config.h> and
<malloc/dynarray-skeleton.c>.
* modules/dynarray (Depends-on): Add intprops.
(Include): Reduce to just "dynarray.h".

* config/srclist.txt: Mention the new files.
* lib/cdefs.h (__attribute_maybe_unused__): New macro,
like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc
naming conventions.
* lib/libc-config.h: Use it instead of __glibc_likely.
* lib/dynarray.h, modules/dynarray: New files.
* lib/malloc/dynarray-skeleton.c, lib/malloc/dynarray.h:
* lib/malloc/dynarray_at_failure.c:
* lib/malloc/dynarray_emplace_enlarge.c:
* lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c:
* lib/malloc/dynarray_resize_clear.c, modules/dynarray:
New files, from glibc with the following changes needed for
portability to compilers that are not recent-enough GCC.
* lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort.
(__libc_dynarray_at_failure) [!_LIBC]: Simply abort.
* lib/malloc/dynarray_emplace_enlarge.c:
* lib/malloc/dynarray_resize.c:
Include intprops.h, and use INT_MULTIPLY_WRAPV instead
of __builtin_mul_overflow.
* lib/malloc/dynarray.h (__libc_dynarray_at_failure):
Use _Noreturn instead of __attribute__ ((noreturn)).
* lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h;
it’s not needed.
(__libc_dynarray_resize_clear): Do not do arithmetic on void *.
* lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT):
Do not use anonymous unions, as they are not in C99. All uses changed.
Use __nonnull (X) instead of __attribute__ ((nonnull X)),
and __attribute_maybe_unused__ instead of __attribute__ ((unused)).
