first steps towards a separated capture tool, working title "dumpcap"

personal backup only, not meant for public testing!

I've copied main.c into dumpcap.c and carved out all things not needed

currently won't work as a command line tool, capture_loop.c wants an input pipe
console output is also very ugly and the whole code needs a lot of further cleanup

shouldn't break the unix build as I've only changed the nmake files so far, but who knows ...
