Nmap tty and NSE

["Patrick Donnelly" <batrick.donnelly () gmail com>]

When speaking to Ron and Brandon about some of the problems debugging
their scripts, I had thought it would be useful to have some form of
interactive debugger they could use at arbitrary moments during a
Script Scan to inspect script threads. In particular, they would like
to see all the threads waiting/running and inspect the stacks of the
threads. I expect it would be as simple as adding an extra character
command (like 'v' increases the verbosity) that signals to NSE the
debugger should run.

I don't think this is possible right now with (the basic) Lua debugger
debug.debug [1] because Nmap takes control of the tty. There would
need to be some changes (while maintaining compatibility) to
nmap_tty.cc module to make this possible. Does this sound like a good
idea?
