* ocd.c: move ocd_write_bytes proto to ocd.h since it is used
        by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define
        BDM_BREAKPOINT if not defined in tm.h
        (ocd_error): add new error cases
        (ocd_start_remote): send the OCD_INIT command before
        OCD_AYT and OCD_GET_VERSION calls, 80 was correct speed after all
        (ocd_write_bytes): no longer static
        (ocd_insert_breakpoint): no longer static
        (ocd_remove_breakpoint): new
        * ocd.h: add protos for ocd_write_bytes, ocd_insert_breakpoint,
        and ocd_remove_breakpoint
        * ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint
        and ocd_remove_breakpoint instead of memory_insert_breakpoint
        and memory_remove_breakpoint.
        (bdm_ppc_open): after calling ocd_open, modify DER
        register so interrupts will drop us into debugging mode, finally
        disable the watchdog timer on the board so we don't leave BDM
        mode unexpectedly.
