shouldn't get you the contents of <unistd.h>.

75ef63d6cf Move some pthread functions to signal.h.
POSIX specifies that pthread_kill(3) and pthread_sigmask(3) are
supposed to live in signal.h rather than pthread.h.

Since signal.h now needs pthread_t and pthread_attr_t, I've moved
those defintions into include/machine/pthread_types.h to keep the
namespace clean. I also sorted some includes. The combination of these
two things seems to have exploded into a cascade of missing includes,
so this patch also cleans up all those.

26a8eb50a8 POSIX says <signal.h> gets you ucontext_t.
POSIX also says that ucontext_t's uc_sigmask has type sigset_t.

MIPS64 strace needs this.

The #define is to keep chromium off our lawn; otherwise it tries to redefine
all this stuff itself. We should probably clean that up and remove the #define.

205dd7d9b3 Remove bsd_signal and sysv_signal from bionic LP64.
bsd_signal was removed in POSIX 2008, sysv_signal was never POSIX.

0990d4fda8 Make SIGRTMIN hide the real-time signals we use internally.
__SIGRTMIN will continue to tell the truth. This matches glibc's
behavior (as evidenced by the fact that we don't need a special case
in the strsignal test now).

a0cd9bc339 Add si_timerid to <signal.h>.
The kernel uses the very misleading name "si_tid", but glibc uses the more
intention-revealing "si_timerid". We should let people use that.

(Added because I wanted to improve SI_TIMER siginfo_t dumping in strace.)

671e236d5f Restore sys_signame for LP64.
mksh is using this, and we probably build as much BSD source as glibc source.

aa0ebdafc7 Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

199346a2ab Fix NSIG.
Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

61fb3fc770 Prepare to switch to the uapi <linux/signal.h>.
<time.h> didn't need to copy the cruft from <signal.h>, and
<signal.h> only needs the uid_t hack when it's not using
uapi headers.

pthread_exit.cpp should include what it uses.

fb5e5cbdd4 Fix an off-by-one error in the sigset_t function error handling.
Spotted while running the tests on MIPS, where sigset_t is
actually large enough. The bits in sigset_t are used such that
signal 1 is represented by bit 0, so the range of signals is
actually [1, 8*sizeof(sigset_t)]; it seems clearer to reword
the code in terms of valid bit offsets [0, 8*sizeof(sigset_t)),
which leads to the usual bounds checking idiom.

da73f655fc Add argument checking to sigemptyset(3) and friends.
You could argue that this is hurting people smart enough to have manually
allocated a large-enough sigset_t, but those people are smart enough to
implement their own sigset functions too.

I wonder whether our least unpleasant way out of our self-inflicted 32-bit
cesspool is to have equivalents of _FILE_OFFSET_BITS such as _SIGSET_T_BITS,
so calling code could opt in? You'd have to be careful passing sigset_t
arguments between code compiled with different options.

c124baaf29 libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>
This patch updates the C library headers to provide ucontext_t
definitions for three architectures.

+ Fix <signal.h> to always define 'struct sigcontext'.

The new declarations are announced with new macros defined in
<sys/cdefs.h> in order to make it easier to adapt client code
that already defines its own, incompatible, versions of the
structures seen here.

5c8c00a95a libc: Fix the definition of SIGRTMAX
After this change, SIGRTMAX will be set to 64 (instead of 32 currently).
Note that this doesn't change the fact that our sigset_t is still defined
as a 32-bit unsigned integer, so most functions that deal with this type
won't support real-time signals though.

This matches recent changes in the NDK header.
We enclose missing functions in #if 0 .. #endif blocks
with a clear "MISSING" in comments in order to locate
them later.
