Hi, This is v2 of the MexTxAttrs update alongside the current state of gdbstub/next (as fixing current_cpu from gdbstub was the original motivation). This includes a little re-factoring to split of the growing gdbstub.c core into smaller discreet units. The first aim of the re-factoring it to remove the kvm specific hacks in gdbstub and replace it with accelerator operations. This will help with enabling debug support on more accelerators by keeping things well partitioned.
Please review.
