- split fileio handling into fileio part and image handling

- reworked etm/etb into a generic etm part with trace capture drivers (currently only etb supported)
- added XScale debug handler binary to repository
- added Thumb disassembling (thanks to Vincent Palatin for this patch)
- added support for non-CFI compatible flashes to cfi driver (currently only SST39VFxxx devices supported)
This checkin is experimental, not suitable for general use
