My recent change to linux-dp.exp wasn't robust because (a) some thread ids can
be negative numbers and (b) sometimes you'd get a 'cannot access memory' error
in printing out a prototype, and that would mess up the \n placement.
This patch fixes those two problems, and renames the tests to be unique.
tested on i686-pc-linux-gnu, ok?

When does (b) happen? That's strange.

Well that's totally lame. I don't see how it happens, either, I'd
expect the error in val_print to catch it.
I think you need to allow newlines in this output anyway; it might wrap
printing many parameters of a function. So may as well just relax the
error for now.

it'd be easy enough to skip unrecognized lines though. but why would it wrap?
there's a 'set width 0' to stop gdb wrapping things.

Oh, guess so. I don't really want to add a patch that recognizes that
error message here; the error message is wrong, we really shouldn't be
printing it.
