Provide ucontext to signal handlers Add ucontext.h header, defining ucontext_t and mcontext_t types. Provide sigaction sighandlers with a ucontext_t parameter, containing stack and context information. * include/sys/ucontext.h : New header. * include/ucontext.h : Ditto. * exceptions.cc (call_signal_handler): Provide ucontext_t parameter to signal handler function.
