	PR 1762/cpukit
	* Makefile.am, preinstall.am, libmisc/Makefile.am, wrapup/Makefile.am:
	Add generic serial mouse driver and mouse parser. The parser code was
	in the pc386 BSP but was generic so cleaned up and placed here.
	Serial mouse driver itself is new.
	* libmisc/mouse/README, libmisc/mouse/mouse_parser.c,
	libmisc/mouse/mouse_parser.h, libmisc/mouse/serial_mouse.c,
	libmisc/mouse/serial_mouse.h: New files.
