Remove stat wrapper functions, move them to exported symbols
This patch removes the stat, stat64, lstat, lstat64, fstat, fstat64,
fstatat, and fstatat64 static wrapper and add the symbol on the libc
with the expected names.
Both the prototypes of the internal symbol linked by the static
wrappers and the inline redirectors are also removed from the installed
sys/stat.h header file. The wrapper implementation license LGPL
exception is also removed since it is no longer statically linked to
binaries.
Internally the _STAT_VER* definitions are moved to a arch-specific
xstatver.h file. The internal defines that redirects internals
{f}stat{at} to their {f}xstat{at} counterparts are removed for Linux
(!NO_RTLD_HIDDEN). Hurd still requires them since {f}stat{at} pulls
extra objects that makes the loader build fail otherwise (I haven't
dig into why exactly).
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

linux: Add {f}stat{at} y2038 support
A new struct __stat{64}_t64 type is added with the required
__timespec64 time definition. Only LFS is added, 64-bit time with
32-bit offsets is not supposed to be supported (no existing glibc
configuration supports such a combination). It is done with an extra
__NR_statx call plus a conversion to the new __stat{64}_t64 type.
The statx call is done only for 32-bit time_t ABIs.
Internally some extra routines to copy from/to struct stat{64}
to struct __stat{64} used on multiple implementations (stat, fstat,
lstat, and fstatat) are added on a extra implementation
(stat_t64_cp.c). Alse some extra routines to copy from statx to
__stat{64} is added on statx_cp.c.
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

linux: Disentangle fstatat from fxstatat
It implements all the required syscall for the all Linux kABIS on
fstatat{64} instead of calling fxstatat{64}.
On non-LFS implementation, it handles 3 cases:
1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and
nios): it issues __NR_fstat64 plus handle the overflow on st_ino,
st_size, or st_blocks.
2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k,
microblaze, mips32, s390, sh, powerpc, and sparc32): it issues
__NR_fstatat64 and convert the result to struct stat.
3. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat.
The generic LFS implementation handles multiple cases:
1. XSTAT_IS_XSTAT64 being 1:
1.1. 64-bit kABI (aarch64, ia64, powerpc64*, s390x, riscv64, and
x86_64): it issues __NR_newfstatat.
1.2. 64-bit kABI outlier (alpha): it issues __NR_fstatat64.
1.3. 64-bit kABI outlier where struct stat64 does not match kernel
one (sparc64): it issues __NR_fstatat64 and convert the result
to struct stat64.
1.4. 32-bit kABI with default 64-bit time_t (arc, riscv32): it
issues __NR_statx and convert the result to struct stat64.
2. Old ABIs with XSTAT_IS_XSTAT64 being 0:
2.1. All kABIs with non-LFS support (arm, csky, i386, hppa, m68k,
microblaze, nios2, sh, powerpc32, and sparc32): it issues
__NR_fstatat64.
2.2. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat64.
It allows to remove all the hidden definitions from the {f,l}xstat{64}
(some are still kept because Hurd requires it).
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

{f}stat{at} to their {f}xstat{at} counterparts are removed for Linux
(!NO_RTLD_HIDDEN). Hurd still requires them since {f}stat{at} pulls
extra objects that makes the loader build fail otherwise (I haven't
dig into why exactly).
Checked with a build for all affected ABIs. I also checked on x86_64,

Remove stat wrapper functions, move them to exported symbols
This patch removes the stat, stat64, lstat, lstat64, fstat, fstat64,
fstatat, and fstatat64 static wrapper and add the symbol on the libc
with the expected names.
Both the prototypes of the internal symbol linked by the static
wrappers and the inline redirectors are also removed from the installed
sys/stat.h header file. The wrapper implementation license LGPL
exception is also removed since it is no longer statically linked to
binaries.

linux: Add {f}stat{at} y2038 support
A new struct __stat{64}_t64 type is added with the required
__timespec64 time definition. Only LFS is added, 64-bit time with
32-bit offsets is not supposed to be supported (no existing glibc
configuration supports such a combination). It is done with an extra
__NR_statx call plus a conversion to the new __stat{64}_t64 type.
The statx call is done only for 32-bit time_t ABIs.
Internally some extra routines to copy from/to struct stat{64}
to struct __stat{64} used on multiple implementations (stat, fstat,
lstat, and fstatat) are added on a extra implementation
(stat_t64_cp.c). Alse some extra routines to copy from statx to
__stat{64} is added on statx_cp.c.
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.

hurd: Factorize at/non-at functions
Non-at functions can be implemented by just calling the corresponding at
function with AT_FDCWD and zero at_flags.
In the linkat case, the at behavior is different (O_NOLINK), so this introduces
__linkat_common to pass O_NOLINK as appropriate.
lstat functions can also be implemented with fstatat by adding
__fstatat64_common which takes a flags parameter in addition to the at_flags
parameter,
In the end this factorizes chmod, chown, link, lstat64, mkdir, readlink,
rename, stat64, symlink, unlink, utimes.
This also makes __lstat, __lxstat64, __stat and __xstat64 directly use
__fstatat64_common instead of __lstat64 or __stat64.

linux: Disentangle fstatat from fxstatat
It implements all the required syscall for the all Linux kABIS on
fstatat{64} instead of calling fxstatat{64}.
On non-LFS implementation, it handles 3 cases:
1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and
nios): it issues __NR_fstat64 plus handle the overflow on st_ino,
st_size, or st_blocks.
2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k,
microblaze, mips32, s390, sh, powerpc, and sparc32): it issues
__NR_fstatat64 and convert the result to struct stat.
3. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat.
The generic LFS implementation handles multiple cases:
1. XSTAT_IS_XSTAT64 being 1:
1.1. 64-bit kABI (aarch64, ia64, powerpc64*, s390x, riscv64, and
x86_64): it issues __NR_newfstatat.
1.2. 64-bit kABI outlier (alpha): it issues __NR_fstatat64.
1.3. 64-bit kABI outlier where struct stat64 does not match kernel
one (sparc64): it issues __NR_fstatat64 and convert the result
to struct stat64.
1.4. 32-bit kABI with default 64-bit time_t (arc, riscv32): it
issues __NR_statx and convert the result to struct stat64.
2. Old ABIs with XSTAT_IS_XSTAT64 being 0:
2.1. All kABIs with non-LFS support (arm, csky, i386, hppa, m68k,
microblaze, nios2, sh, powerpc32, and sparc32): it issues
__NR_fstatat64.
2.2. 64-bit kABI outliers (mips64 and mips64-n32): it issues
__NR_newfstatat and convert the result to struct stat64.
It allows to remove all the hidden definitions from the {f,l}xstat{64}
(some are still kept because Hurd requires it).
Checked with a build for all affected ABIs. I also checked on x86_64,
i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.
