Simplistig locking for --incremental.
...
From: Bill Nottingham <notting@redhat.com>
mdadm --incremental doesn't really do any locking. If you get multiple
events in parallel for the same device (that has not yet started), they
will all go down the path to create the array. One will succeed, the
rest will have SET_ARRAY_INFO die with -EBUSY (md: array mdX already has disks!)
and will exit without adding the disk.
Original bug report is: https://bugzilla.redhat.com/show_bug.cgi?id=433932
This is solved by adding very very rudimentary locking. Incremental() now
opens the device with O_EXCL to ensure only one invocation is frobbing the
array at once. A simple loop just tries to open 5 times a second for 5
seconds. If the array stays locked that long, you probably have bigger
issues.

Small improvements to --incremental for arrays that are in the middle of reshape

There is still a problem: If array is partially assembled and started
read-only, the last device doesn't get added properly. Probably a kernel
problem.

Allow creation of a RAID6 with a single missing device.
...
This did not work before as we couldn't mark it clean as there would
be some parity blocks out of sync, and raid6 will not assemble a
dirty degraded array.
So make such arrays doubly degraded (the last device becomes a spare)
and clean.

Fix problems with array.size overflowing on large arrays.
...
array.size is 32bits and counts K. So for arrays with
more than 4Terrabytes, it can overflow.
The correct number can be read from sysfs, but there are still
a few places that use array.size and risk truncation. What is worse.
they compare a number of kilobytes with a number of sectors !!
So use get_component_size() to read the sysfs information, and be
more consistent about units.

Fix for segfault when reading /proc/mdstat
...
Some kernel versions don't put a space between 'active' and '(auto-read-only)'
in /proc/mdstat. This causes a parsing problem leaving 'level' set to
NULL which causes a crash.
So synthesise a space there if it is missing, and check for 'level' to
be NULL and don't de-ref if it is.

Commit a40b4fe introduced a temporary supertype variable tst, instead of
