preparation for exec.
* syscall:
add syscall.RawSyscall, which doesn't use sys.entersyscall/sys.exitsyscall
add syscall.dup2
add syscall.BytePtrPtr
add syscall.Rusage, RusagePtr
add syscall.F_GETFD, F_SETFD, FD_CLOEXEC
* runtime:
clean up, correct signal handling.
can now survive (continue running after) a signal.
