- using ERROR_COMMAND_SYNTAX_ERROR to print syntax in a couple of places

- some more flash cleanup of checking halted state
- moved output handler into options.c
- very slightly tweaked server.c to make it a bit more compatible with eCos
- retired arch_state. Not quite sure how I managed to leave that out last time.
