Linux 5.3 adds a PTRACE_GET_SYSCALL_INFO constant, with an associated
structure and PTRACE_SYSCALL_INFO_* constants.
This patch adds these to sys/ptrace.h in glibc
(PTRACE_GET_SYSCALL_INFO in each architecture version, the rest in
bits/ptrace-shared.h). As with previous such constants and associated
structures, the glibc version of the structure is named struct
__ptrace_syscall_info.
Tested for x86_64, and with build-many-glibcs.py.
This patch adds the PTRACE_SECCOMP_GET_METADATA constant from Linux
4.16 to all relevant sys/ptrace.h files. A type struct
__ptrace_seccomp_metadata, analogous to other such types, is also
added.
Tested for x86_64, and with build-many-glibcs.py.

Remove compat-specific constants that were never exported by kernel
headers under these names. Before linux commit v3.7-rc1~16^2~1 they
were exported with COMPAT_ prefix, and since that commit they are not
exported at all.
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (__ptrace_request):
Remove arm-specific PTRACE_GET_THREAD_AREA, PTRACE_GETHBPREGS,
and PTRACE_SETHBPREGS.
Move a shared part of sys/ptrace.h which is the same on all
architectures to a separate file.
* sysdeps/unix/sysv/linux/sys/ptrace.h: Include <bits/ptrace-shared.h>.
(__ptrace_setoptions, __ptrace_eventcodes, __ptrace_peeksiginfo_args,

bits/ptrace-shared.h.

Remove enum __ptrace_flags along with the only constant it contains,
PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files.
This temporary development constant shouldn't have been added to
sys/ptrace.h in the first place. It was introduced in Linux by commit
v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE
interface. Later, as PTRACE_SEIZE stabilized and lost its experimental
status, this flag was removed from Linux by commit v3.4-rc1~109^2~20.
* sysdeps/unix/sysv/linux/sys/ptrace.h (enum __ptrace_flags,
PTRACE_SEIZE_DEVEL): Remove.
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h: Likewise.
* sysdeps/unix/sysv/linux/ia64/sys/ptrace.h: Likewise.

Add PTRACE_EVENT_STOP value to Linux's sys/ptrace.h, modify related
comments accordingly.
This constant initially appeared in Linux 3.1 (kernel commit 3544d72a,
"ptrace: implement PTRACE_SEIZE") but its value has changed later
in Linux 3.4 (kernel commit 5cdf389a, "ptrace: renumber
PTRACE_EVENT_STOP so that future new options and events can match").
The comment is also taken from the above commit.
This constant is used by e.g. strace, CRIU, Mozilla RR.
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (__ptrace_eventcodes):
Add PTRACE_EVENT_STOP.

This patch adds some new header definitions from Linux 4.4:
* MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was
already done for hppa).
* PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h. Along with it,
the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux
3.11 but missed at the time, are also added.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

This patch updates <sys/ptrace.h> for Linux 4.3, adding
PTRACE_O_SUSPEND_SECCOMP and updating the value of PTRACE_O_MASK.
Some architectures were missing the older PTRACE_O_EXITKILL, so that
was added to the files missing it as well.
Tested for x86_64 (testsuite, and that installed shared libraries are
unchanged by the patch).

This patch moves the AArch64 port to the main sysdeps hierarchy. The
move is essentially:
git mv ports/sysdeps/aarch64 sysdeps/aarch64
git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64
The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move. The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
