This pull request first moves debug hooks code out of the VR3400 code into a common location usable by both the cpu and rsp. I then add debugging hooks to the rsp and allow the gdb debugger to debug the rsp.
The debugger maps the memory range 0-0x1000 to the rsp IMEM. Adding breakpoints to that memory range will add them to the RSP. All other breakpoints go to the CPU. If a breakpoint is hit in the RSP registers will be read from the RSP in all other cases registers will be read from the CPU.
This PR also maps the memory at 0x04020000 to the vector registers of the RSP but only from the perspective of the debugger. This mapping does't effect the memory bus inside the emulator.
