- explicitly disable monitor mode on ARM7/9 targets

Browse Source 
- added "prepare_reset_halt()" to target_type_t, which allows reset_halt to be prepared before a reset is asserted, possibly preventing communication with the target
- arm7/9 devices now use a breakpoint at 0x0 or reset vector catching for debug out of reset
