overlay/042: remove wrong check for empty index

The check for empty index in this test was wrongly copied from test
overlay/034. In test overlay/034 lower file starts as a hardlink, so
nlink accounting is done from the first copy up and index can be cleaned
on last upper hardlink unlink. In this test, lower starts as
non-hardlink, so first copy up does not perform nlink accounting and
therefore, union nlink count does not drop to 0 at the end of the test
and the index is not expected to be cleaned.

This patch does the nuts and bolts of grabbing fio results and

runs.  This works by storing the results in resuts/fio-results.db as
a sqlite database.  The src/perf directory has all the supporting
python code for parsing the fio json results, storing it in the
database, and loading previous results from the database to compare
with the current results.

This also adds a PERF_CONFIGNAME option that must be set for this to
work.  Since we all have various ways we run fstests it doesn't make
sense to compare different configurations with each other (unless
specifically desired).  The PERF_CONFIGNAME will allow us to
separate out results for different test run configurations to make
sure we're comparing results correctly.

Currently we only check against the last perf result.  In the future
I will flesh this out to compare against the average of N number of
runs to be a little more complete, and hopefully that will allow us
to also watch latencies as well.

generic/166: speed up on slow disks

generic/166 is takes way too long to run on iscsi disks - over an
*hour* on flash based iscsi targets. In comparison, it takes 18s to
run on a pmem device.

The issue is that it takes 3-4s per file write cycle on slow disks,
and it does a thousand write cycles. The problem is taht reflink is
so much faster than the write cycle that it's doing many more
snapshots on slow disks than fast disks, and this slows it down even
more.

e.g. the pmem system that takes 18s to run does just under 1000
snapshots - roughly one per file write. 20 minutes into the iscsi
based test, it's only done ~300 write cycles but there are almost
10,000 snapshots been taken. IOWs, we're doing 30 snapshots a file
write, not ~1.

Fix this by rate limiting snapshots to at most 1 per whole file
write. This reduces the number of snapshots taken on fast devices by
~50% (runtime on pmem device went from 18s -> 8s) but reduced it to
1000 on slow devices and reduced runtime from 3671s to just 311s.

was incorrectly reported as the number of errors.
