	* Significant modifications including adding thread support, the 'X'
	command, and reorganizing so that target CPU independent routines
	could be reused.
	* gdb_if.h: Added numerous prototypes.
	* mips-stub.c: Added thread support as well as 'X' command.
	Also noticed that the 'P' command was from the mips protocol.
	* rtems-stub-glue.c: New file.  This file contains all generic
	support which should be able to be reused on another target CPU.
