[Qemu-devel] GDB stub changes

[Paul Brook]

I've just committed changes to the qemu gdb remote protocol implementation 
that add support for XML register descriptions. This is a relatively new GDB 
feature that allows qemu to describe what CPU registers are available without 
GDB needing prior knowledge of the CPU. Protocol details can be found in the 
GDB documentation. 

Currently only ARM and ColdFire provide these descriptions, and only the basic 
core+fpu registers are described. Future extensions include banked registers, 
privileged registers, MMU state, etc.

Other targets should not see any functional changes. Please test your 
favourite targets and let me know if I broke anything.
