Update sysvipc kernel-features.h files for Linux 5.1
...
Linux 5.1 adds missing SySV IPC syscalls to the syscall table for
remanining one that still uses the ipc syscall on glibc (m68k, mips-o32,
powerpc, s390, sh, and sparc32). However the newly added direct ipc
syscall are different than the old ones:
1. They do not expect IPC_64, meaning __IPC_64 should be set to zero
when new syscalls are used. And new syscalls can not be used
for compat functions like __old_semctl (to emulated old sysvipc it
requires to use the old __NR_ipc syscall without __IPC_64).
Thus IPC_64 is redefined for newer kernels on affected ABIs.
2. semtimedop and semop does not exist on 32-bit ABIs (only
semtimedop_time64 is supplied). The provided syscall wrappers only
uses the wire-up syscall if __NR_semtimedop and __NR_semop are
also defined.
Checked on x86_64-linux-gnu and i686-linux-gnu on both a 4.15 kernel
configure with default options and sysvipc tests on a 5.3.0 kernel with
--enable-kernel=5.1.

sysvipc: Implement semop based on semtimedop
...
Besides semop being a subset of semtimedop, new 32-bit architectures
on Linux are not expected to provide the syscall (only the 64-bit time
semtimedop).
Also, Linux 5.1 only wired-up semtimedop for the 64-bit architectures
that missed it (powerpc, s390, and sparc). This simplifies the code
to support it.
Checked on x86_64-linux-gnu and i686-linux-gnu.

sysvipc: Consolidate semtimedop s390
...
This patch consolidates the s390-32 semtimedop implementation by defining
a arch-specific SEMTIMEDOP_IPC_ARGS to rearrange the arguments expected
by s390 Linux kABI. The idea is to avoid have multiples semtimedop
implementation changes for Linux v5.1 change to enable wire-up sysvipc
support.
Checked with a s390-linux-gnu and s390x-linux-gnu and checking that
resulting semtimedop objects did not change.

Add INLINE_SYSCALL_RETURN/INLINE_SYSCALL_ERROR_RETURN
...
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386
can optimize setting errno by branching to the internal __syscall_error
without PLT.
INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error
number returned from the majority of Linux kernels for which negating
is a no-op with INTERNAL_SYSCALL_ERRNO.
With i386 INLINE_SYSCALL_RETURN, INLINE_SYSCALL_ERROR_RETURN and
i386 syscall inlining optimization for GCC 5, for
sysdeps/unix/sysv/linux/fchmodat.c with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:
