This patch new build tests to check for internal fields offsets for
internal pthread_rwlock_t definition. Althoug the '__data.__flags'
field layout should be preserved due static initializators, the patch
also adds tests for the futexes that may be used in a shared memory
(although using different libc version in such scenario is not really
supported).
Checked with a build against all affected ABIs.

The offsets of pthread_mutex_t __data.__nusers, __data.__spins,
__data.elision, __data.list are not required to be constant over
the releases. Only the __data.__kind is used for static
initializers.
This patch also adds an additional size check for __data.__kind.
Checked with a build against affected ABIs.

The s390 gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77918
"S390: Floating point comparisons don't raise invalid for unordered operands."
is fixed with gcc 10. Thus we conditionally set FIX_COMPARE_INVALID
to 0 or 1.

With only two exceptions (sys/types.h and sys/param.h, both of which
historically might have defined BYTE_ORDER) the public headers that
include <endian.h> only want to be able to test __BYTE_ORDER against
__*_ENDIAN.
This patch creates a new bits/endian.h that can be included by any
header that wants to be able to test __BYTE_ORDER and/or
__FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs
__LONG_LONG_PAIR. It only defines macros in the implementation
namespace.
The existing bits/endian.h (which could not be included independently
of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER)
is renamed to bits/endianness.h. I also took the opportunity to
canonicalize the form of this header, which we are stuck with having
one copy of per architecture. Since they are so short, this means git
doesn’t understand that they were renamed from existing headers, sigh.
endian.h itself is a nonstandard header and its only remaining use
from a standard header is guarded by __USE_MISC, so I dropped the
__USE_MISC conditionals from around all of the public-namespace things
it defines. (This means, an application that requests strict library
conformance but includes endian.h will still see the definition of
BYTE_ORDER.)
A few changes to specific bits/endian(ness).h variants deserve
mention:
- sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to
sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did
have selectable endianness, but we have assembly code in
sysdeps/ia64 that assumes it’s little-endian, so there is no reason
to treat the ia64 endianness.h as linux-specific.
- The C-SKY port does not fully support big-endian mode, the compile
will error out if __CSKYBE__ is defined.
- The PowerPC port had extra logic in its bits/endian.h to detect a
broken compiler, which strikes me as unnecessary, so I removed it.
- The only files that defined __FLOAT_WORD_ORDER always defined it to
the same value as __BYTE_ORDER, so I removed those definitions.
The SH bits/endian(ness).h had comments inconsistent with the
actual setting of __FLOAT_WORD_ORDER, which I also removed.
- I *removed* copyright boilerplate from the few bits/endian(ness).h
headers that had it; these files record a single fact in a fashion
dictated by an external spec, so I do not think they are copyrightable.
As long as I was changing every copy of ieee754.h in the tree, I
noticed that only the MIPS variant includes float.h, because it uses
LDBL_MANT_DIG to decide among three different versions of
ieee854_long_double. This patch makes it not include float.h when
GCC’s intrinsic __LDBL_MANT_DIG__ is available.
* string/endian.h: Unconditionally define LITTLE_ENDIAN,
BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER. Condition byteswapping
macros only on !__ASSEMBLER__. Move the definitions of
__BIG_ENDIAN, __LITTLE_ENDIAN, __PDP_ENDIAN, __FLOAT_WORD_ORDER,
and __LONG_LONG_PAIR to...
* string/bits/endian.h: ...this new file, which includes
the renamed header bits/endianness.h for the definition of
__BYTE_ORDER and possibly __FLOAT_WORD_ORDER.

C2X adds the interfaces from TS 18661-1, and all except a handful in
Annex F are unconditionally visible in C2X rather than only visible
when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates
glibc headers accordingly: most uses of __GLIBC_USE
(IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE
(IEC_60559_BFP_EXT_C2X). (Regarding totalorder and totalordermag, the
type-generic macros in tgmath.h will go away when the functions are
changed to take pointer arguments.)

This patch introduces the new arch13 ifunc variant for memmove.
For the forward or non-overlapping case it is just using memcpy.
For the backward case it relies on the new instruction mvcrl.
The instruction copies up to 256 bytes at once.
In case of an overlap, it copies the bytes like copying them
one by one starting from right to left.

The stub implementations are turned into compat symbols.
Linux actually has two reserved system call numbers (for getpmsg
and putpmsg), but these system calls have never been implemented,
and there are no plans to implement them, so this patch replaces
the wrappers with the generic stubs.
According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>,
the presence of the XSI STREAMS declarations is a minor portability
hazard because they are not actually implemented.
This commit does not change the TIRPC support code in
sunrpc/rpc_svcout.c. It uses additional XTI functionality and
therefore never worked with glibc.

The recent commit 81a14439417552324ec6ca71f65ddf8e7cdd51c7
has introduced __wcscpy, __GI___wcscpy and the weak alias wcscpy.
This patch also introduces those symbols if glibc is build
with CFLAGS="-march=z13" where the ifunc is omitted.
ChangeLog:
* sysdeps/s390/wcscpy-vx.S: Add strong aliases to
__wcscpy, __GI___wcscpy and weak alias to wcscpy.

This patch fixes -Wimplicit-fallthrough warnings in system-specific
code that show up building glibc with -Wextra, by adding fall-through
comments, or moving existing such comments to the place required for
them to work (immediately before the case label being fallen through).
Tested with build-many-glibcs.py.
* sysdeps/i386/dl-machine.h (elf_machine_rela): Add fall-through
comments.
* sysdeps/m68k/m680x0/fpu/s_cexp_template.c (s(__cexp)): Likewise.

This patch makes further coding style fixes where code was breaking
lines after an operator, contrary to the GNU Coding Standards. As
with the previous patch, it is limited to files following a reasonable
approximation to GNU style already, and is not exhaustive; more such
issues remain to be fixed.
Tested for x86_64, and with build-many-glibcs.py.

The recent commit 65f7767a914144ae303f7b9ae81865061793dcb9
has introduced __wmemcmp and the weak alias wmemcmp.
This patch also introduces those symbols if glibc is build
with CFLAGS="-march=z13" where the ifunc is omitted.
ChangeLog:
* sysdeps/s390/wmemcmp-vx.S: Add strong alias to
__wmemcmp and weak alias to wmemcmp.

This fixes the same bug in fnmatch that was fixed by commit 7e2f0d2d77 for
regexp matching. As a side effect it also removes the use of an unbound
VLA.

The ifunc macros s390_vx_libc* are no longer used and
can be removed as all users are now relying on
s390_libc_ifunc_expr.
The same applies to s390_libc_ifunc. The macro
s390_libc_ifunc_init is now renamed to
s390_libc_ifunc_expr_stfle_init and the users are
adjusted accordingly.
ChangeLog:
* sysdeps/s390/multiarch/ifunc-resolve.h
(s390_vx_libc_ifunc, s390_vx_libc_ifunc_redirected,
s390_vx_libc_ifunc2, s390_vx_libc_ifunc_init,
s390_vx_libc_ifunc2_redirected, s390_libc_ifunc):
Delete macro definition.
(s390_libc_ifunc_init): Rename to
s390_libc_ifunc_expr_stfle_init.
* sysdeps/s390/bzero: Use
s390_libc_ifunc_expr_stfle_init instead of
s390_libc_ifunc_init.

The ifunc handling for various __gconv_transform_* functions
which are using IFUNC on s390x are adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Instead those functions are just an alias to the vector variants.
Furthermore the ifunc-macro s390_libc_ifunc_expr is now used instead of
s390_vx_libc_ifunc.
ChangeLog:
* sysdeps/s390/multiarch/gconv_simple.c (ICONV_VX_IFUNC):
Define macro dependent on HAVE_S390_MIN_Z13_ZARCH_ASM_SUPPORT.

The ifunc handling for wmemset is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.

Glibc internal calls will use the "newer" ifunc variant.

The ifunc handling for wcscat is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove wcscat variants.
* sysdeps/s390/Makefile (sysdep_routines): Add wcscat variants.
