The various sys/ucontext.h headers include <signal.h> and all the
headers split out of <bits/sigstack.h>. (Except that the powerpc
version does not include <signal.h>.)
None of the standard versions defining ucontext.h require or permit
such inclusions; rather, they all say that the stack_t and sigset_t
types from signal.h are defined. This patch fixes the headers to
include just the bits/ headers for those types (and the existing
includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now
being included instead of bits/types/__sigset_t.h, __sigset_t uses in
the headers are replaced by direct use of the public sigset_t type.
sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior
inclusion of <signal.h> to define types such as __uint32_t, so gets a
bits/types.h include added to provide those types.
Although one could keep some or all of the includes under a __USE_MISC
conditional, that seems unnecessary to me, especially given the lack
of a <signal.h> include in the powerpc version meaning that portable
programs already cannot rely on such an include.
Tested for x86_64 and x86, and with build-many-glibcs.py. As with
other such fixes, more namespace issues remain so this does not permit
any XFAILs to be removed or bugs to be closed.

The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h. The others
get bits/types/ headers.
Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion. Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API). Relatedly, the public signal.h no longer
declares any of those functions. The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.
New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary. Ports to other operating systems
are strongly encouraged to generalize this scheme further.

bits/sigstack.h contains four things: the legacy struct sigstack type,
the preferred stack_t type, the SS_* enum values and macros for signal
stack sizes.
These vary in different ways between glibc configurations; in
particular, the stack sizes vary much more than any of the other
pieces. Furthermore, these pieces have different standard namespace
rules for when they should be visible (not currently visible in
conform/ results both because the relevant tests are XFAILed for
sys/ucontext.h namespace issues, and because some of the expectations
are incorrect in the same way as the headers, e.g. neither
expectations nor headers reflect that current POSIX no longer has
either the sigstack function or the sigstack structure).
To reduce duplication of identical definitions, and facilitate
namespace fixes without requiring the same feature test macro
conditions to be repeated in many versions of the same header, this
patch splits bits/sigstack.h up into four headers. It keeps the stack
size macros, while new bits/types/struct_sigstack.h,
bits/types/stack_t.h and bits/ss_flags.h are added for the other
pieces. bits/types/struct_sigstack.h is the same everywhere,
bits/types/stack_t.h has three variants different in the order of the
structure elements (generic = MIPS Linux, and other Linux), and
bits/ss_flags.h has generic and Linux variants.
This patch includes the new headers everywhere that included
<bits/sigstack.h>, so should cause no difference to what any public
header defines. Subsequent namespace fixes would then remove or
condition some of those includes.
There should be no conflicts with Zack's changes to signal.h types,
beyond the trivial conflict of both making additions to
signal/Makefile's headers list; the two patches affect disjoint sets
of types and other definitions.

This constant initially appeared in Linux 3.1 (kernel commit 3544d72a,

in Linux 3.4 (kernel commit 5cdf389a, "ptrace: renumber

The comment is also taken from the above commit.

Fix powerpc-specific headers:
- Make it compatible to C89 by replace references to inline by __inline__.
- Get the definition of sigset_t used by
sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h.
- Includes missing header file.
sys/ucontext.h unconditionally uses stack_t, and it does not make
sense to change that. But signal.h only declares stack_t under
__USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is
already in a bits header, bits/sigstack.h, but that header insists on
only being included by signal.h, so we have to change that as well as
all of the sys/ucontext.h variants. (Some but not all variants of
bits/sigcontext.h, which sys/ucontext.h may also need, had already
received this adjustment; for consistency, I made them all the same,
even if that's not strictly necessary in some configurations.)
bits/sigcontext.h and bits/sigstack.h also all need to receive
multiple inclusion guards.

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).

All the other ptrace structures in this file have a __ prefix except this
new one. This in turn causes build problems for most packages that try to
use ptrace such as strace:
gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \
-I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \
-MF .deps/process.Tpo -c -o process.o ../../process.c

Since this struct was introduced in glibc-2.18, there shouldn't be any
real regressions with adding the __ prefix.
