Remote set thread breakpoint

[Fabian Cenedese]

Hi

I'm thinking about extending the remote protocol for thread breakpoints.
The easiest solution would be to just add another data field to the Z
commands, like:

Ztype,addr,length,threadid

If threadid is given, gdbserver can use it. If it's -1 or not present (as in
the present implementation) it's a global breakpoint.

But if this would cause incompatibilities with existing parsers it may
be better to create a new command, even if it's just Z5 and the rest
is the same.

What would be better? Or is something like that already in the pipe?

Thanks
