* main.c: Make baud_rate and remote_debug be global variables,

remove #include "remote-utils.h".  This makes it possible to build
	GDB without remote-utils.c.  Also, move setting of remote_debug
	into main, so that all remote*.c files can use it (not just the
	serial line ones).  And, make baud_rate be an int.
	* remote-udi.c:  Change kiodebug to remote_debug.
	* remote-utils.c:  Move setting of baud rate and debug into main.c.
	* remote-utils.h:  Redefine sr_{get set}_debug and sr_{get set}_baud
	to use baud_rate and remote_debug globals for compatibility.
	* remote.c:  Use remote_debug and baud_rate globals directly,
	instead of sr_ functions, so that we don't need to load
	remote-utils.c.
