lmc creates a default one-stripe LOV for no LOV added with lmc

- additional assert

NOTE: it passes sanity and single-replay

  is very simple: don't drop i_nlink to 0 in ext3_unlink() if file is
  large

NOTE: to be discussed yet

NOTE: do not use it for a while, please. ext3-delete-thread must
      be reworked first.

fix renaming a file to itself, and add a couple of tests for this

fix a bug in --disable-doc handling, and add snapfs to DISTDIRS

r braam

perl llanalyze dk.str -dlm MDC_uml_mds1_MNT_localhost

perl llanalyze dk.str \
 -extract_start="004000:000400:0:1073288749.491802:1780:898:6772" \
 -extract_end="000040:080000:0:1073288750.493802:1652:974:7014"

 - call vfs_rmdir() on directory orphans when removing them from
   PENDING
 - add a test for this case to replay-single
 - add open(O_DIRECTORY) to multiop

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

Make sure we reset the timer after resending a request.  Renamed
sending_error to force_timer_recalc, because that's what it does.

Merging fix from b_llp2. Set the rq_no_resend for cancel requests so
ldlm_cli_cancel() can reconstruct the cancel with the correct
cookie.
