crashed during the critcal phase.

Fix a warning about an uninitialised variable.

The case that doesn't initialise it is impossible,

Add new mode: --incremental

--incremental allows arrays to be assembled one device at a time.
This is expected to be used with udev.

Don't hold md device open for so long in --monitor mode

map_dev can be slow and interferes with trying to stop the array.

Change handling for "--assemble --force" when two drives disappeared at once.
...
If two drives in a raid5 disappear at the same time, then "-Af"
will add them both in rather than just one and forcing the array
to 'clean'. This is slightly safer in some cases.

Change 'Device Size' to 'Used Dev Size'

how big they are.

Increase raid456 stripe cache size if needed to --grow the array.

The setting used unfortunately requires intimate knowledge of the
kernel, and it not reset when the reshape finishes.

get created automatically, as this is almost always what is wanted.

Make Assemble/Force work on raid6 with 2 missing devices.
...
Previously it onl worked when one missing device.
Also split the "force" update_super method into two and it
is really serving two functions.

Fixed problems that could cause infinitel loop with auto assemble.
...
If an auto-assembly attempt failes because the array cannot be
opened or because the array has already been created, then we
get into an infinite loop.

Mdassemble improvements
...
From: Luca Berra <bluca@comedia.it>
- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
This is useful if they are started read-only as is best at boot-time.

Work around bug in --add handling for version-1 superblocks
...
In 2.6.17 (and prior), the dev_number is ignored when a device
is added to an active array. Rather the first free number is used.
So we work around this by making sure we use the first free
number for dev_number.
