Fix replay-single.sh and recovery-small.sh so they can run with the
default lmv config or "-f cfg/local.sh" config.

- b1_4 is basically the parent of HEAD, because that's the direction
  that changes flow, as strange as that sounds.  so there's a
  HEAD_BASE tag which sits on b1_4

b_cmobd_merge should not be used for any further development or testing!

cMD_PRE_CMD_SMASH are the relevant tags.

The pre-smashing contents of HEAD will be committed by yury into b_cmd as a
merge of the two branches.  These will be stabilized on b_cmd and eventually
landed onto HEAD.

- add a new test (18a) to use lctl --deactivate to confirm page cache is
  cleared after invalidation.
- rename 18 to 18b, and increase wait to ensure the cache is checked after
  recovery

r=zab (partial)

Better handling for OST eviction.  Fixes for clearing the page cache,
imp_invalid handling, and improved import_event interface. Also
includes the tests and fixes added from 2732; one of those tests does
not yet passed so it is excepted for now.

  updated insanity

The principal change here is ptlrpc_connect_import and recovery are
merged and are now asynchronous and are run on ptlrpcd.

This branch also includes fixes for

  2477 (this was the initial bug)

  2355 recover for initial connections

  1934 (b_1934 was merged directly to b_recovery)

  1901 block all file creations until orphan recovery completes

  2423 client remove rq_connection from request struct

  2640 conf-sanity test_5, and proper cleanup in umount when
       cleanup log is not availale.

  2670 recovery timer race

  2532 mdc_close recovey bug

And few others that werent' filed.

test cases for these bugs.
Also some test enhancments
  - add more lctl marks
  - add SETUP CLEANUP options to replay-single

Add a test to recovery-small to trigger this bug. Also fix some
typos/brainos in recovery-small and test-framework, and set the debug
level to the default for local configs,

  now run in a local, single node mode by default.

- Add some tests for old bugs to recovery-small.sh. These tests were
  in the ltest/recovery scripts, but that is now unused.

- Move the OBD_FAIL funcs to test-framework.

- add the -v command line option for test scripts; it will print out
  the commands its executing on the nodes.

 - dozens and dozens of fixes for working with 2.6 kernels
 - new 2.4 kernel APIs
 - uncountable bug fixes
