A few changes, now that a few rbd problems have been fixed.
First, the more substantive changes:
- Generate a source file, and compare what's read back from rbd
devices with the content of that file.
- Write to the rbd device such that the written data spans
an (assumed 4 MB) rbd object boundary, as well as starting
and ending on non-page-aligned offsets.
- Perform multiple reads on rbd devices: entirely within a range
before any written data; beginning before but ending within
written data; the exact written data (and validating what's
read); beginning within written data but ending after it;
reading after written data but within a written rbd object;
and reading from an unwritten rbd object.
- Have the sleep between iterations provide a non-integer value
to avoid zero (or quantized) delays.
Also, some a little less substantive (but possibly informative):
- Don't run with "set -x". It produces a ton of noise that is
not useful for this test. This is an exerciser, looking
really for system crashes during concurrent activity, and
knowing which commands were (concurrently) active isn't going
to help much in diagnosis.
- Create two more directories, used to track the degree of
concurrency (more or less) and the highest rbd id consumed.
Files whose names are numbers are touched in each, and the
highest at the end is the highest during the run. This gets
around issues passing environment info from sub-shells to the
top-level shell. As a bonus, it offers a better chance of
avoiding problems due to concurrent update.
- NAMESDIR is renamed NAMES_DIR, and it (and the others) is
set up in the setup() function.
- Increase the concurrency and iteration counts.
- Move the default definitions before the ceph secrets stuff

This tests for the behavior reported in #3964. It passes on the current
code, but fails on 3.2 in squeeze (and 32-bit?).

This defines a new workunit shell script that performs a bunch of
rbd operations concurrently in order to exercise code paths and
catch reference count and bad pointer problems.

Add tests for:
- sparse import makes expected sparse images
- sparse export makes expected sparse files
- sparse import from stdin also creates sparse images
- import from partially-sparse file leads to partially-sparse image
- import from stdin with zeros leads to sparse
- export from zeros-image to file leads to sparse file

It turns out that our suites don't exercise fsync, at least not very much
(I couldn't find it in all the places I looked for it). This tester
was written by Ted T'so and updated by Chris Mason; I just made it
work on a smaller dataset (256MB) because 8GB against a small cluster takes
more time than we want to wait.

This script was heuristically using short sleep commands in order to
give udev activity time to complete.
There's a command "udevadm settle" which actually looks at the udev
queue and waits until its processing is done. Much, much better.
This rearranges the get_id function a bit too, breaking it into one
function that gets the id and another that loops back and tries
again after a short delay in the event the get_id fails.
