If we're doing write/overwrite/snapshot/resource exhaustion tests on
the scratch device, use the test directory to hold the loop
termination signal files. This way we don't run infinitely because
we can't create the flag due to ENOSPC.

There're many tests don't remove $seqres.full before writing to it, and
accumulating logs there, then the logs are always growing over time.
Let's fix them once.
generic/16[1-8] generic/170 and generic/33[34] truncate $seqres.full in
the middle of the test, which results in partial logs. Fix them as well.
xfs/227 has duplicated lines to remove $seqres.full, remove the extra
line.

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'

Set up an impossibly small filesystem and try to reflink and rewrite a
file on it to see what happens when we ENOSPC. Basically
generic/16[67] but with a constrained fs size.
