bdca3802c9 Remove unnecessary padding in ucontext_t
- removed extra padding from ucontex_t on x86, x86_64 and mips
- force ucontext_t struct to use 64 bits for the sigmask on all arches
(previsouly wrong since sigset_t on arm and x86 is only 32 bits)
- arm and arm64 continue to use padding to match glibc sigset_t

This brings Bionic on par with the kernel w.r.t ucontext padding.

eb454522da Clean up ucontext.h TODOs.
There's no need to expose gregset_t and fpregset_t when they
are not used in ucontext_t.

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.
