Subject: [PATCH] XBoard: make messages compatible with xboard protocol.

Introduces the "xboard" global var, but only yhe last commit will set
it, when support is complete.

Some non-compliant utterances had to be disarmed by commenting them
out with a leading '#'.

YD: split original patch into a series
