contrib/itmdump: add a hack to allow direct dumping of specific SWIT
Currently itmdump is not a production-quality code anyway hence this
hack seems to be appropriate.
This adds a new command line option -d N where N is a stimulus number
you want to dump (counting from 1).
The idea here is that if you're interested to live-monitor just a
single stimulus port, you can use this utility directly. If one wants
to demultiplex the TPIU stream, the following is proposed:
1. Find or write an utility that can accept binary data from a
file/pipe/stdin and arbitrary number of TCP connections. It should
simply mirror all the incoming data to all the accepted connections;
2. Use socat to connect itmdump to the proxy mentioned in 1. and then
either dump the results to separate files or share via their dedicated
TCP ports (similar to what http://openocd.zylin.com/1662 does).
