insanity and recovery-small cleanup (patless unrealted)

Use lmv by default for insanity.sh.

- Fix insanity.sh, still using the insanity-local.sh config by default.
- More cleanups in replay-single.sh. We need to generalize failures a
bit more, so we can choose a different mds each time, if more than one
is available.

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.
