Use to avoid starting arrays if there are
fewer devices available than last time the array was started.
This is only needed with --scan, as with --scan, that behaviour
is the default.

So when you say auto=md or auto=part in mdadm.conf, it give a preference
for type of array, but standard name will override.
But --auto=md is more insistant.
FIXME I'm not at all happy about handling of names that already exist.
I don't think that should be removed if the device is active.

When creating a file bitmap, choose a default size that
results in fewer than 2^21 chunks. Without this kmalloc
failure in the kernel becomes likely.

To support resizing an array without a spare, mdadm now understands
--backup-file=
which should point to a file for storing a backup of critical data.
This can be given to --grow which will create the file, or
--assemble which will restore from the file if needed.

Hi Neil,
While adding the text message mode, I saw a FIXME asking for syslog
support in monitor mode.
This patch adds exactly that.

If a bad file names was given, exit status still 0.
If some devices couldn't be stopped for "mdadm -Ss"
exit status still 0.

The device= list is still available if --verbose is given (once).

metadata format is being used, and so the max number of raiddisks

This allows for larger device number if glibc supports
it (requires 2.3.3).
Also fail before creating larger device number if glibc
support isn't present.
