qemu-option: warn for short-form boolean options
Options such as "server" or "nowait", that are commonly found in -chardev,
are sugar for "server=on" and "wait=off". This is quite surprising and
also does not have any notion of typing attached. It is even possible to
do "-device e1000,noid" and get a device with "id=off".
Deprecate it and print a warning when it is encountered. In general,
this short form for boolean options only seems to be in wide use for
-chardev and -spice.
