Once the monitor thread has kicked a drive from all managed arrays mdadm
-r is permitted. We are guaranteed that the drive is marked failed at

start_mdmon now waits for mdmon to complete initialisation and,
importantly, listen on the socket, before continuing.

The returned value was never used, and we don't really want
this return path anyway as writing to a pipe could conceivably
block, and the monitor must not block.

Each md_message encapsulates a single command. A command includes an 'action'
member which describes what if any data comes after the action. Communication
with the monitor involves updating the active_cmd pointer and then writing to
mgr_pipe. Pass/fail status is returned via mon_pipe.
