LU-1778 llite: fix inconsistencies of root squash feature

Root squash exhibits inconsistent behaviour on a client when
enabled. If a file is not cached on the client, then root will get
a permission denied error when accessing the file. When
the file has recently been accessed by a regular user and is
still in cache, root will be able to access the file without error
because the permission check is only done by the client that
isn't aware of root squash.

While the only real security benefit from root squash is to deny
clients access to files owned by root itself, it also makes sense
to treat file access on the client in a consistent manner
regardless of whether the file is in cache or not.

This patch adds root squash settings to llite so that client is able
to apply root squashing when it is relevant.

Configuration of MDT root squash settings will automatically be
applied to llite config log as well.

Update cfs_str2num_check() routine by removing any modification
of the specified string parameter. Since string can come from ls_str
field of a lstr structure, this avoids inconsistent ls_len field.

LU-4528 llog: don't write llog in 3-steps

The llog record my be written by passing just buffer
and writting its header and tail separately. If any write fails
then that cause partially written buffer and corrupted llog. There is
special undo procedure to clean things up after that but that demands
twice more credits for normal operations and for undo case which
is critical in case of wide striping.

Such 3-steps write can be avoided by preparing correct llog record
before calling llog_write().

Patch does the following:
- remove all cases with passing separate buffer for llog_write(),
llog_add(), llog_cat_add() and change API according with that.
- special allocation case for lustre_cfg if it is going to be written
to the llog, it allocates llog header/tail and initialize it.
- uniform error checks after lustre_cfg_new() call to check for NULL
result always instead of ERR_PTR()
- remove 3-steps write in llog_osd code completely
- write llog padding record in single step too
- remove duplicated code from llog_cat_new_log(). Previously it
assigned the next index for the record, changed bitmap and called
llog_write with new index, so that was considered as 'modification'
of record but not append. Meanwhile the llog_osd_write_rec() does
the same intenally for append request. Now llog_cat_new_log() just
calls llog_write() with -1 index (append), avoiding all header
changes outside that call.
- remove numcookie parameter from llog_write_rec() because it is
always 1 anyway
- remove cookie parameter from llog_write() because it is not used,
note, the cookie remains as parameter of llog_write_rec() for llog
catalog purposes.

LU-4609 ofd: auto resume LFSCK after the recovery

To prevent the LFSCK to recreate some objects which should be done
via some replayable RPCs, we will postpone the LFSCK auto assuming
after the server restart until the recovery finished.

Such serialization also avoid some race between LFSCK and recovery
to misguide the LFSCK to regard the system as inconsistent.

Another fix is that:
During the OST recovery, the client write RPC may create the missed
OST-object which will cause the real last_id to be greater than the
last_id value stored in the LAST_ID file temporarily. Normally, the
LAST_ID file will be synced between MDT and OST during the recovery,
but we should not assume that the MDT-OST recovery will succeed. If
it failed, then subsequent LFSCK on the OST may regard such LAST_ID
file as crashed, then it will mark the OST as read-only and rebuild
the LAST_ID files.

To avoid such case, before the write RPC to create the lost object,
it needs to update the LAST_ID file firstly.

2. sub-stripe object will be inserted into master object

By this, it will remove those specilities for stripe0 in

This patch also fixes a few things in osp orphan iteration, to

1. stripe 0 should be locked as EX, same as other stripes.
2. Acquire the layout for directory, when it is being unliked.

LU-4578 ptlrpc: Early replies need to honor at_max

When determining whether an early reply can be sent the server will
calculate the new deadline based on an offset from the request
arrival time. However, when actually setting the new deadline
the server offsets the current time. This can result in deadlines
being extended more than at_max seconds past the request arrival
time. Instead, the server should offset the arrival time when updating
its request timeout.

When a client receives an early reply it doesn't know the server side
arrival time so we use the original sent time as an approximation.

LU-4388 io: pass fsync() range through RPC/IO stack

The Linux VFS and Lustre OST_SYNC RPC are both capable of specifying
fsync() on a sub-extent of the file {start, end} instead of the full
file.  This allows less than the full amount of data to be flushed,
reducing or possibly eliminating the work needed before the syscall
can return.

However, the handling of sub-extent of the file for fsync was lost
with the move to CLIO on the client and OSD API on the server.  They
were ignoring the passed {start, end} and using {0, OBD_OBJECT_EOF}
instead.

Return the ability to pass a sub-extent for fsync() from the client,
to the specific stripes/OSTs that need the sync operation, and pass
it down to the OSD.  The ZFS OSD doesn't handle this yet, but there
is room for improvement in a separate patch.

LU-4855 fld: refer to MDT0 for fld lookup in some cases

It is possible that when fld client is trying to lookup seq
on one of MDT, but the connection between the client and the MDT
is not being initialized yet, especially during striped dir creation,
because client will only send create req to the master MDT, then
master MDT will distribute the operation to all of other MDT, instead
of client distributing these requests, which will usually trigger
the connection.

In this case, we will send the fld request to MDT0, since it has
all of location information.

It turns out that sec_null message format is is not double wrapped

LU-4819 tests: Lustre Sanity test_101b hangs for large OSTCOUNTs

sanity.sh test_101b hangs during Lustre sanity test. This
is happening especially in cases where the $OSTCOUNT is
greater than 100.

Due to OSTCOUNT of more than 100, the ITERATION parameter
results in '0', which causes the 'reads' utility to run
in infinite 'for' loop. Thus resulting in a hang on such
setups.

This change would make necessary changes in FILE_LENGTH in
test_101b and its related routines(setup_101bc, ra_check)
so that, the test won't hang and would proceed rightly.
