50080a29f7 Remove the ___ hack.
Plain __ for generated syscalls didn't mean it was a hidden symbol, it
just meant "please don't use this". We added ___ to signify that a
hidden symbol should be generated, but then we added the map files
anyway so you now have to explicitly export symbols. Given that, this
convention serves no particular purpose so we may as well just use the
nicer names have everything look the same.

baf20fc912 Block TIMER_SIGNAL in sigprocmask(SIG_SETMASK, ...).
Previously, we were zeroing out the reserved signals, when we actually
wanted to have TIMER_SIGNAL always be blocked, and the other signals
always be unblocked. This resulted in process termination when a
SIGEV_THREAD timer callback calls sigprocmask(SIG_SETMASK, ...) with
any signal mask value, and then subsequently fails to complete its
callback and reach the sigtimedwait in bionic before the next timer
iteration triggers.

Add a how argument to filter_reserved_signals to appropriately
block/unblock our reserved signals.

6fcba93b17 Filter out reserved signals in functions that take sigset_t.
Prevent processes from blocking libc-reserved signals by filtering them
out.

7ae39129e1 Move sigprocmask into its own file.
Otherwise clang inlines it into pthread_sigmask(3), which breaks libsigchain.

5905d6f879 Add sigset64_t and accompanying functions.
This doesn't address `struct sigaction` and `sigaction`. That will
come later.

1721cd6a74 Make _signal hidden in all cases.
_signal was static in 64 bit, and hidden on 32 bit. There is no
reason to have this distinction, so make it hidden in all cases.

8b5df3920f Turn on -Wold-style-cast and fix the errors.
A couple of dodgy cases where we cast away const, but otherwise pretty boring.

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

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.
