This reverts commit 3d3572f590.
Reason for revert: TCGETS etc. work to some extent on at least
a subset of architectures, so there is no pressing need to force
applications off them. Removal of the macros breaks building
the sanitizers, impacting both GCC and LLVM.

Undefine TCGETS, TCGETS2, and related ioctl constants in the installed
headers. Extract the correct constants (using the kernel type
definitions) automatically from the UAPI headers. The kernel
constants are available under KERNEL_* names during the glibc build,
computed using assembler constant extraction mechanism.
Alpha may have to use TCGETS instead of TCGETS2 because TCTGETS2
became available in Linux 4.20 only. Introduce ARCH_TCGETS to make
this choice explict.
To support emulation on powerpc, glibc versions of the termios
constants are added to the emulation code in internal-ioctl.h.

Linux has supported arbitrary speeds and split speeds in the kernel
since 2008 on all platforms except Alpha (fixed in 2020), but glibc
was never updated to match. This is further complicated by POSIX uses
of macros for the cf[gs]et[io]speed interfaces, rather than plain
numbers, as it really ought to have.
On most platforms, the glibc ABI includes the c_[io]speed fields in
struct termios, but they are incorrectly used. On MIPS and SPARC, they
are entirely missing.
For backwards compatibility, the kernel will still use the legacy
speed fields unless they are set to BOTHER, and will use the legacy
output speed as the input speed if the latter is 0 (== B0). However,
the specific encoding used is visible to user space applications,
including ones other than the one running.
- SPARC and MIPS get a new struct termios, and tc[gs]etattr() is
versioned accordingly. However, the new struct termios is set to be
a strict extension of the old one, which means that cf* interfaces
other than the speed-related ones do not need versioning.
- The Bxxx constants are redefined as equivalent to their integer
values and the legacy Bxxx constants are renamed __Bxxx.
- cf[gs]et[io]speed() and cfsetspeed() are versioned accordingly.
- tcgetattr() and cfset[io]speed() are adjusted to always keep the
c_[io]speed fields correct (unlike earlier versions), but to
canonicalize the representation to ALSO configure the legacy fields
if a valid legacy representation exists.
- tcsetattr(), too, canonicalizes the representation in this way
before passing it to the kernel, to maximize compatibility with
older applications/tools.
- The old IBAUD0 hack is removed; it is no longer necessary since
even the legacy c_cflag baud rate fields have had separate input
values for a long time.

Linux 6.0 adds a constant ADDRB, a termios c_cflag bit, to its
include/uapi/asm-generic/termbits-common.h.
Add it accordingly to glibc's bits/termios-c_cflag.h headers. As
other constants in these headers are generally in octal, I converted
the value to octal to match. As ADDRB isn't in a POSIX-reserved
namespace, I made it conditional on __USE_MISC.

This is clever, but it confuses downstream detection in at least zstd
and GNOME's glib. zstd has preprocessor tests for the 'st_mtime' macro,
which is not provided by the path using the anonymous union; glib checks
for the presence of 'st_mtimensec' in struct stat but then tries to
access that field in struct statx (which might be a bug on its own).

It refactor how signals are defined by each architecture. Instead of
include a generic header (bits/signum-generic.h) and undef non-default

common definition (bits/signum-generic.h) and each architectures add
its specific definitions on a new header (bits/signum-arch.h).
For Linux it requires copy some system default definitions to alpha,
hppa, and sparc. They are historical values and newer ports uses
the generic Linux signum-arch.h.

On y2038 safe 32-bit systems the Linux kernel expects itimerval
and rusage to use a 32-bit time_t, even though the other time_t's
are 64-bit. There are currently no plans to make 64-bit time_t versions
of these structs.
There are also other occurrences where the time passed to the kernel via
timeval doesn't match the wordsize.
To handle these cases let's define a new macro
__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64. This macro specifies if the
kernel's old_timeval matches the new timeval64. This should be 1 for
64-bit architectures except for Alpha's osf syscalls. The define should
be 0 for 32-bit architectures and Alpha's osf syscalls.

Add a new macro __STATFS_MATCHES_STATFS64 that specifies if fsblkcnt_t
matches fsblkcnt64_t and if fsfilcnt_t matches fsfilcnt64_t.
As we don't have the padding we also need to update the overflow checker
to not access the undefined members.
This patch sets the mode field in ipc_perm as mode_t for all architectures,
as POSIX specification [1]. The changes required are as follow:
1. It moves the ipc_perm definition out of ipc.h to its own header
ipc_perm.h. It also allows consolidate the IPC_* definition on
only one header.
2. The generic implementation follow the kernel ipc64_perm size so the
syscall can be made directly without temporary buffer copy. However,
since glibc defines the MODE field as mode_t, it omits the __PAD1 field
(since glibc does not export mode_t as 16-bit for any architecture).
It is a two-fold improvement:
2.1. New implementation which follow Linux UAPI will not need to
provide an arch-specific ipc-perm.h header neither wrongly
use the wrong 16-bit definition from previous default ipc.h
(as csky did).
2.1. It allows consolidate ipc_perm definition for architectures that
already provide mode_t as 32-bit.
3. All kernel ABIs for the supported architectures already provides the
expected padding for mode type extension to 32-bit. However, some
architectures the padding has the wrong placement, so it requires
the ipc control routines (msgctl, semctl, and shmctl) to adjust the
mode field accordingly. Currently they are armeb, microblaze, m68k,
s390, and sheb.
A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the
required ABIs define.
4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also
require compat symbols that do not adjust the mode field.
Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu,

The kernel changes for a 64-bit time_t on 32-bit architectures
resulted in <asm/socket.h> indirectly including <linux/posix_types.h>.
The latter is not namespace-clean for the POSIX version of
<sys/socket.h>.
This issue has persisted across several Linux releases, so this commit
creates our own copy of the SO_* definitions for !__USE_MISC mode.
The new test socket/tst-socket-consts ensures that the copy is
consistent with the kernel definitions (which vary across
architectures). The test is tricky to get right because CPPFLAGS
includes include/libc-symbols.h, which in turn defines _GNU_SOURCE
unconditionally.
Tested with build-many-glibcs.py. I verified that a discrepancy in
the definitions actually results in a failure of the
socket/tst-socket-consts test.

This patch consolidates the termios symbolic constants used as subscript
for the array c_cc on its own header. The Linux generic implementation
values match the kernel UAPI and each architecture with deviate values
have their own implementation (in this case alpha, mips64, sparc64, and
powerpc).
No semantic change is expected, checked on a build against x86_64-linux-gnu,
alpha-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu.

This patch consolidates the struct termios definition on its own header
and adds arch-defined ones for ABIs that deviate from generic
implementation. They are:
- alpha which has a slight different layout than generic one (c_cc
field is defined prior c_line).
- sparc and mips which do not have the c_ispeed/c_ospeed fields.
No semantic change is expected, checked on a build against x86_64-linux-gnu,
alpha-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu.

sysdeps/unix/sysv/linux/bits/shm.h has padding after time fields in
struct shmid_ds unconditionally, and thus is only suitable for 32-bit
architectures (no 64-bit configurations use this file);
sysdeps/unix/sysv/linux/generic/bits/shm.h is substantively the same,
except that the padding is conditioned on __WORDSIZE == 32, and so it
can be used for 64-bit architectures as well.
This patch adds the conditionals to
sysdeps/unix/sysv/linux/bits/shm.h. The linux/generic/ version is
then no longer needed and so is removed, as are the alpha and s390
versions which are also no longer needed. The other
architecture-specific versions have different padding, layout, types
or SHMLBA definitions and so are still needed after this change.
This is essentially the same change for bits/shm.h as the bits/msq.h
patch and the bits/sem.h patch. However, the details of the padding
variations for the architectures that aren't changed are not all the
same between msqid_ds, shmid_ds and semid_ds.

This patch completes the process of unifying sys/procfs.h headers for
architectures using the Linux kernel by making alpha use the generic
version.
That was previously deferred because alpha has different definitions
of prgregset_t and prfpregset_t from other architectures, so changing
to the common definitions would change C++ name mangling. To avoid
such a change, a header bits/procfs-prregset.h is added, and alpha
gets its own version of that header.
Tested for x86_64 and x86, and with build-many-glibcs.py.

<bits/procfs-prregset.h>.

This patch makes the alpha bits/termios.h define XTABS to TAB3, so
matching a change made in Linux 4.16 as well as matching other
architectures where the values are already equal.
Tested with build-many-glibcs.py for alpha-linux-gnu.

Fix the RLIM_INFINITY and RLIM64_INFINITY constants on alpha to match
the kernel one and all other architectures. Change the getrlimit,
getrlimit64, setrlimit, setrlimit64 into old compat symbols, and provide
the Linux generic functions as GLIBC_2_27 version.
Changelog:
* sysdeps/unix/sysv/linux/getrlimit64.c [USE_VERSIONED_RLIMIT]: Do not
define getrlimit and getrlimit64 as weak aliases of __getrlimit64.
Define __GI_getrlimit64 as weak alias of __getrlimit64.
[__RLIM_T_MATCHES_RLIM64_T]: Do not redefine SHLIB_COMPAT, use #elif
instead.
* sysdeps/unix/sysv/linux/setrlimit64.c [USE_VERSIONED_RLIMIT]: Do not
define setrlimit and setrlimit64 as weak aliases of __setrlimit64.
* sysdeps/unix/sysv/linux/alpha/bits/resource.h (RLIM_INFINITY,
RLIM64_INFINITY): Fix values to match the kernel ones.
* sysdeps/unix/sysv/linux/alpha/getrlimit64.c: Define
USE_VERSIONED_RLIMIT. Rename __getrlimit64 into __old_getrlimit64 and
provide it as getrlimit@@GLIBC_2_0 and getrlimit64@@GLIBC_2_1. Add a
__getrlimit64 function and provide it as getrlimit@@GLIBC_2_27 and
getrlimit64@@GLIBC_2_27.
* sysdeps/unix/sysv/linux/alpha/setrlimit64.c: Ditto with setrlimit
and setrlimit64.

setrlimit, getrlimit64 and setrlimit64.
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.
This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.
For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round. This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.
For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.
(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)
Tested for x86_64, and with build-many-glibcs.py.
