* 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.
