As the final act in this patchset, adjust the "This file is part of
the GNU C Library" message at the top of each file to indicate which
files are synced with gnulib.
* posix/bits/getopt_core.h, posix/bits/getopt_ext.h
* posix/getopt.c, posix/getopt1.c, posix/getopt_int.h:
Mention in top-of-file boilerplate that these files are shared
with gnulib.
* posix/getopt.h, posix/bits/getopt_posix.h:
Mention in top-of-file boilerplate that these files are NOT shared
with gnulib, unlike the rest of the getopt implementation.

_getopt_data.__posixly_correct is completely redundant to
_getopt_data.__ordering, and some work that logically belongs in
_getopt_initialize was being done by _getopt_internal_r, making the
code harder to understand.
As a side effect, getenv will no longer be called if the first
character of the options string is '+' or '-', which is probably a
Good Thing. (Perhaps we should have a flag character that
specifically asks for the permutation behavior?)
* posix/getopt_int.h (_getopt_data): Remove __posixly_correct field.
* posix/getopt.c (_getopt_internal_r): Move some initialization code...
(_getopt_initialize): ...here. Don't set d->__posixly_correct.

For standards compliance, getopt, getopt_long, and getopt_long_only in
glibc have to take 'char *const *argv' even though they can mutate the
array. gnulib has tried to clean this up as much as possible: all the
internal functions use 'char **argv', and when used standalone, so do
getopt_long and getopt_long_only.
Also brought over are __nonnull annotations, corrections to documentation,
and apparently it is no longer necessary to worry about conflicting
prototypes for getopt. The macroification of the definitions of
getopt and __posix_getopt goes beyond what is currently in gnulib.
At this point getopt1.c and getopt_int.h are identical to their gnulib
versions.
* posix/getopt.h: Add backup definition of __nonnull for
consistency with gnulib. Define __getopt_argv_const to const
if not already defined.
(getopt): Update doc comment from gnulib. Prototype
unconditionally. Add __nonnull annotation.
(__posix_getopt): Add __nonnull annotation.
(getopt_long, getopt_long_only): Use __getopt_argv_const in
prototypes for consistency with gnulib. Add __nonnull
annotations.
* posix/getopt.c (_getopt_initialize, _getopt_internal_r)
(getopt_internal): Change 'argv' argument to type 'char **'.
Remove now-unnecessary casts.
(getopt, __posix_getopt): Eliminate repetition with a macro.
Cast 'argv' to 'char **' when calling _getopt_internal.
* posix/getopt1.c (getopt_long, getopt_long_only):
Use __getopt_argv_const for consistency with gnulib.
Cast 'argv' to 'char **' when calling _getopt_internal.
(_getopt_long_r, _getopt_long_only_r):
Change 'argv' argument to type 'char **'.
(main): Constify 'long_options'.
* posix/getopt_int.h (getopt_internal, _getopt_internal_r)
(_getopt_long_r, _getopt_long_only_r):
Change 'argv' argument to type 'char **'.

This covers changes with little or no consequences when the code is
used in glibc.
* posix/getopt_int.h: Include getopt.h.
Use impl-namespace names for all arguments to _getopt_internal and
_getopt_internal_r.
Declare __ordering enum outside the struct.
Harmonize comments with gnulib.
* posix/getopt1.c: Simplify #ifdeffage at top of file. Remove
ELIDE_CODE logic entirely. Move inclusion of stdlib.h to
#ifdef TEST block and make unconditional. Do not define NULL.
* posix/getopt.c: Partial merge from gnulib, covering the
initial includes and global declarations, commentary, and
a couple of semantically-neutral code changes.

I'm not sure whether this is official GNU style now, but `...' quotes
haven't looked properly balanced in most people's terminal fonts since
2001ish? and gnulib has chosen to switch over to '...' quotes.
I'm merging this separately from the other changes in gnulib because
it's very mechanical.
* posix/getopt.c, posix/getopt.h, posix/getopt1.c, posix/getopt_int.h:
Use '...' instead of `...' for quotation marks inside
comments and strings.

glibc's implementation of getopt includes code to parse an environment
variable named _XXX_GNU_nonoption_argv_flags_ (where XXX is the
current process's PID in decimal); but all of it has been #ifdefed out
since 2001, with no official way to turn it back on.
According to commentary in our config.h.in, bash version 2.0 set this
environment variable to indicate argv elements that were the result of
glob expansion and therefore should not be treated as options, but the
feature was "disabled later" because "it caused problems". According
to bash's CHANGES file, "later" was release 2.01; it gives no more
detail about what the problems were.
Version 2.0 of bash was released on the last day of 1996, and version
2.01 in June of 1997. Twenty years later, I think it is safe to
assume that this environment variable isn't coming back.
* config.h.in (USE_NONOPTION_FLAGS): Remove.
* csu/init-first.c: Remove all #ifdef USE_NONOPTION_FLAGS blocks.
* sysdeps/mach/hurd/i386/init-first.c: Likewise.
* posix/getopt_int.h: Likewise.
* posix/getopt.c: Likewise. Also remove SWAP_FLAGS and the
__libc_argc and __libc_argv externs, which were only used by
#ifdef USE_NONOPTION_FLAGS blocks.
* posix/getopt_init.c: Remove file.
* posix/Makefile (routines): Remove getopt_init.
* include/getopt.h: Don't declare __getopt_initialize_environment.
* manual/getopt.texi: Remove mention of USE_NONOPTION_FLAGS in
a comment.
