Add the ability to create a log file for debugging output

Browse source 
Especially when asking non-developers for help debugging a problem it can
be extremely useful to have debugging output not go to the console but to
a log file instead.

This just adds the infrastructure to create (and close) such a file. No
changes to the debug output are made.

All this is of course #ifdef'ed out.
