* Merged r46kstub.c into RTEMS distribution without modification.
	I got the code from Franz Fischer <Franz.Fischer@franz-fischer.de>
	who had used this with an old version of RTEMS with the mips64orion
	port of RTEMS.  After adding this to the repository, I will tailor
	this to work with the RTEMS exception processing model and trim
	no longer needed parts.
	* ChangeLog, gdb_if.h, ioaddr.h, limits.h, Makefile, mips_opcode.h,
	r4600.h, r46kstub.c, r46kstub.ld, README, stubinit.S:

c/src/lib/libbsp/mips/shared/gdbstub/gdb_if.h
