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 _test_mount performs "_test_mount ; _test_umount"
so mechnically rename this function to _test_cycle_mount. This was
done mechnically using the script fragment:
git grep -E "_test_remount" | \
awk -F: '{print $1}' | sort -u | grep -v tests/xfs/189 \
xargs sed -i 's/_test_remount/_test_cycle_mount/g'

Fix style problems such as unnecessary use of quotes, add helper
variables to reduce visual clutter, and other minor fixes to make the
first batch of tests more closely resemble the second round tests.

Since $TESTDIR is a local variable, make it lowercase to avoid
confusion with $TEST_DIR. While we're at it, make all the local
variables lowercase.
