Delete lies from x86_64 setjmp implementation.
Previously, the implementation of setjmp on x86_64 claimed that
sigprocmask would write to two longs' worth of bytes.

Silence false positive warnings on GCC.
We still use GCC to build the bionic unit tests into CTS, and it emits a
false positive -Wmissing-field-initializers warning for the C++11 aggregate
initialization syntax `Foo foo = {}`.

debuggerd: rethrow the full signal we receive, always.
The previous code assumed that returning would be sufficient to rethrow
signals like SIGSEGV. This is not true, for example, in the case where a
SIGSEGV is sent via kill(2). We were previously only sending the signal
to ourselves in some cases, because using kill(2) would lose information
in the siginfo_t argument. Use rt_tgsigqueueinfo(2) instead to preserve
its contents.

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).

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.

Fix up failing glibc tests.
There is a known bug running clone with the CLONE_VM flag, so for host
create an empty test.
Change the expected output of the stdio test for a glibc difference.
Change the pause test to use ScopedSignalHandler to setup/restore the SIGALRM
handler.
After this, running bionic-unit-tests-glibc passes for all tests.

Fix raise(3) so it works in signal handlers.
We could special-case raise(3) in non-threaded programs, but the more
conservative course is to make pthread_kill(3) work in signal handlers
at the cost of a race shared by other C libraries.

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.

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.
