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.

c7e9b23317 Fix sigaction(3) for 64-bit.
Also clean up <signal.h> and revert the hacks that were necessary
for 64-bit in linker/debugger.cpp until now.

156ccf42ff update signal.h to be C90 compatable
sigismember, sigaddset, and sigdelset had mixed code and declarations
which are not allowed in C90 and before.

41b3179c9e Unit tests for formatting code, fix %%.
Also fix <signal.h> and <stdio.h> so they don't cause compiler warnings.

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.

c1b44ecc53 Revert "libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>"
This creates build issues in the internal Android tree.
Will investigate later.

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.

bb5581ad6e libc: tag missing functions in system headers.
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.
