This patch adds three operations for new EH. The operations are...
->freeze freeze the port
->error_handler new EH
->post_internal_cmd EH/clean up for internal commands
The old and new EH's have to live together for the time being and
->error_handler will be used as a switch to select which EH mechanism
to use.
