1) _require_fiemap and _require_xfs_io_command "fiemap" do the
same thing, but some test cases use the former and some use
the latter, so i feel they should be unified.
2) The number of helpers like this is slowly growing, but it's
easy to simply use _require_xfs_io_command directly and just
specify the command we want to check.
This is just a cleanup for keeping it simple.

Add a leading underscore to the get_block_size helper since it's a

This makes it clear when we are using "mount ; umount" versus "mount
-o remount" for most file systems. The reason for this distinction is
(a) tests may want to test the difference between what happens on the
remount versus the munt paths, (b) with tmpfs, "mount ; umount" will
cause the contents of all of the files to disappear which makes many
tests sad, and (c) some mount options may not be changed using "mount
-o remount".
Currently _scratch_mount performs "_scratch_mount ; _scratch_umount"
so mechnically rename this function to _scratch_cycle_mount. This was
done mechnically using the script fragment:
git grep "_scratch_remount" | \
awk -F: '{print $1}' | sort -u | \
xargs sed -i 's/_scratch_remount/_scratch_cycle_mount/g'

Perform copy-on-writes at random offsets to stress the CoW allocation

combatting fragmentation via unshare, a rewrite, and no-op after the
