From: Yong Sun <sunyong0511@gmail.com>
Recently LTP upstream removed some ext4 tests[1].
And two of them is still valid to keep. So I transport those two tests here.
ext4-nsec-timestamps, which is used to test nanosec timestamps of ext4, rewrite into ext4/043 and 044.
ext4-subdir-limit, which is used to test subdirectory limit of ext4, rewrite into ext4/045.

v2: Correct copyright information
v3: Correct white-space damage
v4: Add a missing file
v5: Fix several issue reviewed by Darrick
v6: Fix several issue reviewed by Eryu, and remove block setting in ext4/045
Refer to ext4/045 fail https://www.spinics.net/lists/linux-ext4/msg69467.html

It'd be good to have one program be able to create both long and short
dirs, having two progorams to do similar tasks seems not necessary.

The echo'ed messages are all refering to sec_atime.
And above checks are unable to detect the case that $sec_xtime is
smaller than $sec, as ($sec_xtime - $sec) becomes negative.
We have a _within_tolerance helper to check if the value is within a
given value. Please see other tests for examples.
