LU-797 tests: fix ost-pools test timeout issues on b1_8

The test time of the ost-pools subtests is unreasonably long.

test_14 fills an OST to 90% full, regardless of the OST size.
Skip the test if the amount of data to be written is too large
to run in a practical time.

test_18 creates 3x3x30000 files to compare performance with/without
pools enabled.  Instead of creating a fixed number of files, use
createmany to run for a specific (short) time to measure
performance.

test_23 tried to fill all OSTs 100% full.  Split this test into two:
- test_23a to test quota with a file in a pool
- test_23b to test OOS with a file striped over pool

The following patches are merged into this one:
- LU-797 tests: speed up ost-pools tests
(master patch eea698c944283b755882d8f504d2fcc8ea371bd8)
- LU-797 tests: skip ost-pools.sh 23b when SLOW=no

A deadlock can occur with the kthread_stop_lock mutex because
ldiskfs_put_super calls kthread_stop on an already stopped thread
(kmmpd) so it waits for completion of the thread stopping before
releasing the kthread_stop_lock.

This is the result of a race with the kmmpd thread setting s_mmp_tsk
to NULL and ldiskfs_put_super in another thread to checks s_mmp_tsk
for NULL prior to calling kthread_stop.

LU-425 tests: fix the issue of using "grep -w"

This patch fixes the following issue while using "grep -w"
to do exact match:

$ echo /mnt/nbp0-2 | grep -w /mnt/nbp0
/mnt/nbp0-2

Per the description of "-w" option:
-w, --word-regexp
Select only those lines containing matches that form whole words.
The test is that the matching substring must either be at the
beginning of the line, or preceded by a non-word constituent
character. Similarly, it must be either at the end of the line
or followed by a non-word constituent character. Word-constituent
characters are letters, digits, and the underscore.

So, the hyphen "-" character is a non-word constituent character
and "grep -w" does not do exact match on strings which contain it.

LU-995 utils: make lfs getstripe directory output consistent.

"lfs getstripe" should report the global default for any fields with
a value that means "use the default". This patch introduces the
following functionality:

1. If "lfs getstripe" is called on a directory and finds that striping
   EA is not set, the filesystem's defaults are looked up and printed.
2. If the striping EA is set, but the striping count and/or striping
   size has a value that means "use the default" (count = 0 and/or
   size = 0), the filesystem's default for that specific striping
   attribute is looked up and printed.
3. A new option to "lfs getstripe" is introduced; the "--raw" or
   "-R" option. If this option is specified, the previous two checks
   are skipped. In other words, if the striping EA is not set, 0, 0,
   -1, will be printed for the striping count, size, and offset
   respectively. Also, if the striping EA is set, the values will be
   printed without first converting them into their respective
   defaults.

This patch relies on the /proc filesystem to determine each
filesystem's default striping attributes, and a cache is maintained
which holds the default values for the last filesystem queried.

for other uses.  The upcoming quota code needs to store another
FID into the LDLM resource to allow directory tree quotas, and
managed by the DLM.

The 32-bit VER, which is currently always 0, is moved into the high
bits of name[1] along with the 32-bit OID, to avoid consuming the
name[2] field.  Since future use of the FID version (including
snapshots, pools, etc) will need changes on the client side anyway,
there will never be non-zero VER on an existing client.

LU-164 Update testframework to restart sessions at next suite

Update the test framework so that it can append to yaml files rather
than begin a new series and allow auster to begin at a selected
test_suite.

auster has a new switch '-S suite-name' which allows the caller to
start a test group part way through.

The idea behind all of this is that a test session that fails at a
test suite can be restarted at the next suite.

LU-983 llite: align readahead to 1M after ra_max adjustment

Align the readahead pages only if ria_start != 0, otherwise the
readahead pages will be cut to zero. And it can be checked by
checking (ret > ((ria->ria_start + ret) % PTLRPC_MAX_BRW_PAGES))

Add test_101e for checking small reads for small size files.

Put 101a to Exception list, because it will do random small
reads(64k) on the file, then checking pages being discarded.
But in current implementation, we will always extend small size
read to 1M during read-ahead, which might cause too much unused
pages being read, then being discarded later.

Remove big rpc check in 101c, because the test will do random small
size(64K) read, so it only need make sure there are no small size
RPC during the read. Besides, the original big RPC check is wrong,
since it can not make sure all of RPC exists in this case.
