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.

Alex Bennée (9):
  hw: encode accessing CPU index in MemTxAttrs
  qtest: make read/write operation appear to be from CPU
  hw/intc/gic: use MxTxAttrs to divine accessing CPU
  hw/timer: convert mptimer access to attrs to derive cpu index
  configure: move detected gdb to TCG's config-host.mak
  gdbstub: move into its own sub directory
  gdbstub: move sstep flags probing into AccelClass
  gdbstub: move breakpoint logic to accel ops
  gdbstub: move guest debug support check to ops
