There used to be an asm-generic/signal.h, but not one that
could be used out of the box. This renames the existing file
to asm-generic/signal-defs.h and adds a new asm-generic/signal.h
with common definitions for sigaction and sigaltstack, but
not for the old-style signal handlers.

New architectures should only implement rt-signals and use this
generic header.
