36d6188f8c Clean up forking and cloning.
The kernel now maintains the pthread_internal_t::tid field for us,
and __clone was only used in one place so let's inline it so we don't
have to leave such a dangerous function lying around. Also rename
files to match their content and remove some useless #includes.

bf425680e4 Let the compiler worry about implementing ffs(3).
It does at least as good a job as our old hand-written assembly anyway.

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.

19e62325c2 Clean up the sigprocmask/pthread_sigmask implementation.
Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs
can share the same code as the 32-bit ABIs.

Also, let's test the return side of these calls, not just the
setting.

2a0b873065 Fix __errno for LP64 and clean up __get_tls.
If __get_tls has the right type, a lot of confusing casting can disappear.

It was probably a mistake that __get_tls was exposed as a function for mips
and x86 (but not arm), so let's (a) ensure that the __get_tls function
always matches the macro, (b) that we have the function for arm too, and
(c) that we don't have the function for any 64-bit architecture.

4906e5653c Add arch-x86_64/bionic.
This is basically half of I5de76f6c46ac87779f207d568a86bb453e2414de from
Pavel Chupin <pavel.v.chupin@intel.com>, but with the stock upstream
setjump/sigsetjmp and H.J. Lu's suggested changes to __rt_sigreturn.

a567a8e4bd x86_64: Update Makefiles for x86_64 targets and add symlinks
Use basic .c versions of all functions for x86_64 until they are
manually optimized and .s versions released.
