Connect to the monitor in the old namespace and use that connection for
WaitClean requests when stopping the victim mdmon instance. This allows
ping_monitor() to work post chroot().

It is currently possible to remove a device and re-add it without the
manager noticing, i.e. without detecting a mdstat->devcnt
container->devcnt mismatch. Introduce ping_manager() to arrange for
mdmon to run manage_container() prior to mdadm dropping the exclusive
open() on the container. Despite these precautions sysfs_read() may
still fail. If this happens invalidate container->devcnt to ensure
manage_container() runs at the next event.

Data is being passed in shared memory, so the pipe is only being
use as a wakeup. This can more easily be done with a thread-signal.

This really should be done in mdadm, not mdmon.
We ensure the device won't be suddenly commited as a hot-spare
using O_EXCL, then check the 'holders' sysfs directory
to make sure it is only in use once.

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.
