It is possible for the mapfile to become wrong, and that gets
very confusing. So validate entries before returning them.

Rather than appending the md minor number, we now append a small
sequence number to make sure name in /dev/md/ that aren't LOCAL are
unique. As the map file is locked while we do this, we are sure
of no losing any races.

This only applies if udev isn't installed or is disabled
by MDADM_NO_UDEV
We try to remove partitions too.
We find names to remove by looking in /var/run/mdadm/map

We previously only updated /var/run/mdadm/map when starting an
array with --incremental. However we now make more use of
that file (to pass the dev name to udev) so always update it.

There was a bug. If /var/run/mdadm/ did not exist as a directory,
the map file should have been created in /var/run/mdadm.map, but
due to bug it would never get created.
