[PATCH] gdb: add -a option for remove-inferior

[sbaugh@catern.com]

I find myself frequently wanting to wipe out the current set of
inferiors: detaching from all of them, or killing them all, and then
starting anew. A -a flag to the various inferior commands which currently
just take ranges of ids would make this a lot easier. Does that sound
like a reasonable enhancement?

If this patch is acceptable I'll go ahead and add -a flags like this to
all the inferior commands where it makes sense, and add docs, and
resubmit.


This adds a -a option for remove-inferior; when passed, all inferiors
will be removed.
