sigcontext/mcontext cleanup for arch-specific bits
with these changes, the members/types of mcontext_t and related stuff should closely match the glibc definitions. unlike glibc, however, the definitions here avoid using typedefs as much as possible and work directly with the underlying types, to minimize namespace pollution from signal.h in the default (_BSD_SOURCE) profile. this is a first step in improving compatibility with applications which poke at context/register information -- mainly debuggers, trace utilities, etc. additional definitions in ucontext.h and other headers may be needed later. if feature test macros are used to request a conforming namespace, mcontext_t is replaced with an opaque structure of the equivalent size and alignment; conforming programs cannot examine its contents anyway.
