4fa9b3bfe6 Fix mcontext_t sigcontext namespace (bug 21457). 
This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.

Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel.  This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).

Tested for x86_64, and with build-many-glibcs.py.

3d452dabd1 Fix uc_* namespace (bug 21457). 
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.

The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>).  Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.

This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined.  Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.

This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).

Tested for x86_64, and with build-many-glibcs.py.

251287734e Rename struct ucontext tag (bug 21457). 
The ucontext_t type has a tag struct ucontext.  As with previous such
issues for siginfo_t and stack_t, this tag is not permitted by POSIX
(is not in a reserved namespace), and so namespace conformance means
breaking C++ name mangling for this type.

In this case, the type does need to have some tag rather than just a
typedef name, because it includes a pointer to itself.  This patch
uses struct ucontext_t as the new tag, so the type is mangled as
ucontext_t (the POSIX *_t reservation applies in all namespaces, not
just the namespace of ordinary identifiers).  Another reserved name
such as struct __ucontext could of course be used.

Because of other namespace issues, this patch does not by itself fix
bug 21457 or allow any XFAILs to be removed.

Tested for x86_64, and with build-many-glibcs.py.

139904b7e4 Fix more namespace issues in sys/ucontext.h (bug 21457). 
Continuing the fixes for namespace issues in sys/ucontext.h, this
patch moves various symbols into the implementation namespace in the
absence of __USE_MISC.  As with previous changes, it is nonexhaustive,
just covering more straightforward cases.

Structure fields are generally changed to have a prefix __ in the
absence of __USE_MISC, via a macro __ctx (used without a space before
the open parenthesis, since the result is a single identifier).
Various macros such as NGREG also have leading __ added.  No changes
are made to structure tags (and thus to C++ name mangling), except
that in the (unused) file sysdeps/i386/sys/ucontext.h, structures
defined inside other structures as the type for a field have their
tags removed in the non-__USE_MISC case (those structure tags would
not in any case have been visible in C++, because in C++ the scope of
such a tag is limited to the containing structure).  No changes are
made to the contents of bits/sigcontext.h, or to whether it is
included.  Because of remaining namespace issues, this patch does not
yet fix the bug or allow any XFAILs to be removed.

Tested for x86_64 and x86, and with build-many-glibcs.py.

cfed8ece79 Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457). 
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.

a992f506ff Remove __need macros from signal.h. 
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.

0bcec5321f Split up bits/sigstack.h. 
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.

Tested for x86_64 and x86, and with build-many-glibcs.py.

5df4854ed2 Condition some sys/ucontext.h contents on __USE_MISC (bug 21457). 
Continuing the fixes for namespace issues arising from sys/ucontext.h,
this patch conditions various definitions, that are not needed for
defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear
in strict POSIX modes.

This patch is non-exhaustive; that is, it only conditions
straightforward cases and there may be more such definitions that can
be conditioned for these and other architectures, to be dealt with
later in separate patches.  Also, using __USE_MISC is the minimum
change for these definitions where they conflict with POSIX; some
headers already have __USE_GNU conditionals on similar definitions of
names for registers.  The patch specifically does not do anything with
definitions in bits/sigcontext.h, and nor does it condition any
inclusions of bits/sigcontext.h even where in fact that is not needed
on some architectures for the definitions of mcontext_t / ucontext_t.

As other namespace issues in these headers remain, this patch does not
fix bug 21457, nor allow any XFAILs to be removed.

Tested with build-many-glibcs.py.

c66b29f9cc Installed-header hygiene (BZ#20366): stack_t. 
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.
