hw/xwin: turn on -emulate3buttons if less than 3 mouse buttons are reported

Try to be more intelligent with default options, turn on -emulate3buttons by
default if less than 3 mouse buttons are reported by Windows

Also, add -noemulate3buttons option so this default setting can be reversed
if desired

Also, correctly report the number of mouse buttons windows is reporting, rather
than always at least 3
