This reverts commit 3ba34141.
It breaks the MinGW build and should be first tested on a
branch.

posix_spawn is less error-prone than vfork + exec, and can make use of
system-specific optimizations like `clone' on Linux.  Import Gnulib
replacement so that we can use recent additions like
`posix_spawn_file_actions_addchdir'.

The only manual change are to admin/merge-gnulib and .gitignore.  All
other changes are due to rerunning merge-gnulib.

* admin/merge-gnulib (GNULIB_MODULES): Add posix_spawn-related
modules.
* .gitignore: Add new generated files.

The latest Gnulib merge brought in free-posix, which causes 'free'
to preserve errno.  This lets us simplify some Emacs code that
calls 'free'.
* admin/merge-gnulib (GNULIB_MODULES): Add free-posix.
This module is pulled in by canonicalize-lgpl anyway,
so we might as well rely on it.
* lib-src/emacsclient.c (get_current_dir_name):
Sync better with src/sysdep.c.
* lib-src/etags.c (process_file_name, etags_mktmp):
* lib-src/update-game-score.c (unlock_file):
* src/fileio.c (file_accessible_directory_p):
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by assuming that 'free' preserves errno.
* src/alloc.c (malloc_unblock_input):
Preserve errno, so that xfree preserves errno.
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by using strdup instead of malloc+memcpy.
No need for realloc (and the old code leaked memory anyway on
failure); just use free+malloc.

* admin/authors.el (authors): Make the error message more helpful.
(authors-ignored-files, authors-renamed-files-alist): Update.

* admin/emake: Colorize error messages.

* admin/release-process (refcards):
* admin/make-tarball.txt (refcards): Update information about
generating refcards and required TeX/LaTeX packages.

* admin/charsets/mule-charsets.el: Use lexical-binding.
(mule-charsets-header): Rename from 'header' to silence byte-compiler.

These were all tested and confirmed working.

It wasn’t needed for MinGW after all, no other platform
seems to need it, and it slows down ‘configure’.

Needed for platforms like MinGW that don’t support C99 PRIdPTR.
