Change 48691 by marcel at marcel_nfs on 2004/03/11 00:14:25

	o  Add gdb/gdb_main.c, which declares the KDB backend and
	   defines the GDB debug port set.
	o  Implement gdb_init() so that debug ports are scanned.
	o  Hook gdb_main.c & uart_dbg.c into the build.
	
	Note: the GDB backend does not define a trace function and
	the enter function can be omitted as well (entry into the
	kernel will then always happen through the trap function).
	The trap function is not implemented.
