This patch makes the remote-mips target register a SIGINT handler
instead, like monitor.c does.

Of course, only after doing this, I noticed that that there's
no configuration currently that builds this file...

I've checked that this at least builds after tweaking configure.tgt
to include it in a --target=mips-elf build.  CS has a similar tweak
in its internal trees, but AFAIK we don't have customers
using this target either.

To make this build, I also needed to change regcache_set_valid_p to
regcache_invalidate.  regcache_set_valid_p isn't defined anywhere.

It seems it would supposed to go in with this:
http://sourceware.org/ml/gdb-patches/2007-12/msg00150.html

But only the remote-mips.c bits went in.

Anyway, as long as I've written it the patch here it is.
