* coffgrok.[ch]: New files, understand coff objects.

	* coffdump.c: Uses coffgrok to dump out the debug info of a coff
	file.
	* sysroff.info: Description of a SYSROFF object file.
	* sysinfo.y, syslex.l: Parse info file, generate a reader, writer,
	header files and a printer.
	* srconv.c: Uses coffgrok.c and sysroff.info to convert a coff
	file to a SYSROFF file.
