We only really have one remote protocol -- gdb-remote. And we haven't
shied from introducing extensions to it in the past, so I don't see why
we couldn't add one for remote tab-completion.

I don't think that should be a lot of work -- the code for tab
completion is already there, so it should mostly be a matter of plumbing
the request through the gdb-remote classes. I think that could be useful
at times -- I find the ssh remote tab completion in bash pretty useful.

That said, it's quite possible there are other tab-completion-y things
that could be done and which have a better cost-benefit ratio.
