Allow setting mdc.*.max_mod_rpcs_in_flight > mdc.*.max_rpcs_in_flight
by increasing the latter value, rather than returning an error and
telling the user to do that.  This matches the similar behavior if
mdc.*.max_rpcs_in_flight is reduced lower than max_mod_rpcs_in_flight.

If there are multiple MDTs, the "mdc.*.max_mod_rpcs_in_flight" param
may be set from e.g. the MDT0000 config log before MDT0001 is fully
configured, catching MDT0001 with ocd_maxmodrpcs = 0 before the OCD
from the MDT has been filled in, and incorrectly trigger an error.
If seen during setup, allow ocd_maxmodrpcs = (max_rpcs_in_flight - 1),
since this will be fixed up later if mdc.*.max_rpcs_in_flight is set
smaller in the config log (if set larger it doesn't matter).

The sanity test_160f test was failing intermittently because the first
Changelog user ("cl6") was being unregistered in some cases when it
set changelog_max_idle_time=10, but the test slept for 9s and then did
some operations that could be slow.  In rare cases the test runs too
long and the MDS evicts the "good" user along with the bad user:

   MDD0000: Force deregister of ChangeLog user cl7 idle more than 35s
   MDD0000: Force deregister of ChangeLog user cl6 idle more than 11s

Change the test sleep interval to be half of the max_idle limit so
that there is no risk of the "good" Changelog user being evicted.

Add some logging to the test so that it is easier to correlate test
script actions with events in the MDS debug log.

However this assert is being triggered in some rare scenarios.
The reason tx_sending would be 0 at this point is because:
 1. ib_post_send() failed but OFED stack is still sending

 2. We're getting two different events for the same tx

Add a bash completion for "lfs" and improve completion for "lctl".
Rename the "lctl" completion script to "lustre" since the two
commands share helper routines for fsnames, pools, etc. and install
"lfs" and "lctl" symlinks to the common command file.

The completion prints available sub-commands and their options,
and for some sub-commands it completes available arguments
(e.g. mount points, pool names, and MDT/OST names).

A couple of minor changes to "lfs" and "lctl" usage messages to make
the sub-command options easier to parse.  More needs to be done to
make all sub-commands have proper long options.

There is definitely more that could be added to the completions,
but this is a good start and provides a framework for the future.

Add function lod_striped_lookup() for
lod_striped_index_ops.dio_lookup to allow name lookup under striped
directory.

Currently this is used by subdir mount, which needs to lookup FID
of the subdir on server side.

Function lfsck_namespace_repair_dirent() should call dt_lookup() with
bottom object, because child may be shard.

The "size_units" variable was not being reset while parsing different
"lfs setstripe" arguments, so e.g. "lfs setstripe -E 1M -S 65536 ..."
ended up using the 'M' unit for the stripe size, which resulted in a
stripe_size of 65536MiB = 64GiB, which resulted in an error.

This only appeared with PFL or other layout patterns which had more
than one unit being parsed, and was already fixed in master via SEL.
