ucontext_t available. Our code even has XXX comment about this. Add a bit of compliance by moving struct __ucontext definition into sys/_ucontext.h and including it into signal.h and sys/ucontext.h. Several machine/ucontext.h headers were changed to use namespace-safe types (like uint64_t->__uint64_t) to not depend on sys/types.h. struct __stack_t from sys/signal.h is made always visible in private namespace to satisfy sys/_ucontext.h requirements. Apparently mips _types.h pollutes global namespace with f_register_t type definition. This commit does not try to fix the issue.
