super1: reserve at least 2 chunks for reshape headroom.
reserved more space in a RAID5, so we need to update to array
sizes when reshaping.
Also make sure reshape tests we change the shape: raid5->raid1
was failing and we didn't notice.

Default metadata type is now 1.2, and we sometimes
add extra alignment before the data section,
so adjust tests for these changes.

1.1 is more flexible in a number of ways and is safer.
0.90 is still fully supported.
1.0 should possibly be used for RAID1 arrays that you
want to boot off, depending on your boot loader.

This seems more appropriate for current (and recent) model drives than
64K.
64K is still the default for '--build' as changing that could corrupt
data.
64K is also the default rounding for 'linear' on kernels older than
2.6.16.
