[issue7245] better Ctrl-C support in pdb (program can be resumed)

No,I don't think patch in the issue #1294 addresses the problem which
I'm trying to solve.

I tried applying patch#1294, and Ctrl-C will still throws your debugger
into postmortem mode and I don't think you can change that by overriding
do_KeyboardInterrupt(): when do_KbdInterrupt() is called you cannot
resume execution (or at least I don't know any way of doing it).

My patch handles the SIGINT directly which allows it to set tracing and
resume the program immediately (and keyboardinterrupt is never raised)

I'll also add comments to patch#1294
