Setting term_size to the current size if None

[timgabets]

This improvement may be useful for the 'remote' debugging in a next terminal tab - in this case the debugger window will be opened with a full screen resolution, not with 80x24

Thanks for your contribution!

I'd like to see more error handling here, so that even if this fails, it doesn't make matters worse. I'm also not a fan of doing this via a subprocess, since there are many situation where forking a aubprocess is undefined behavior, such as when a GPU context is active, or when the process is part of an MPI communicator that's backed by a DMA-based network such as Infiniband. Coincidentally, these are primary uses (for me) of remote debugging. I'd prefer this IOCTL-based solution.

Lastly, if available, this should just use Python's built-in facility to get the terminal size.

Sorry for a late reply.

Umm, well, as I see, shutil.get_terminal_size() is only available for Python 3. Checking a python version inside of the set_trace() looks a little ugly to me, but if it's OK to you, I'll do it.

That's just the cost of doing business in Py2 and 3, to my mind at least.

Done
