LU-3233 mdt: validate open handle cookies

Add a const void *h_owner member to struct portals_handle. Add a const
void *owner parameter to class_handle2object() which must be matched
by the h_owner member of the handle in addition to the cookie.  Adjust
the callers of class_handle2object() accordingly, using NULL as the
argument to the owner parameter, except in the case of
mdt_handle2mfd() where we add an explicit mdt_export_data parameter
which we use as the owner when searching for a MFD. When allocating a
new MFD, pass a pointer to the mdt_export_data into mdt_mfd_new() and
store it in h_owner. This allows the MDT to validate that the client
has not sent the wrong open handle cookie, or sent the right cookie to
the wrong MDT.

When a client accesses data in a released file,

During this restore, the client must not glimpse and

LU-3483 llite: Null deref in ll_revalidate_nd on NFSmount

In calls to ll_revalidate_nd, the nameidata pointer nd is
sometimes null.  The core code of the function tests for
this case and handles it by calling ll_node_revalidate_it.
However, immediately before that code, there is a test to
see if the LOOKUP_RCU flag is set in nd->flags.  This test
does NOT check to see if the nd pointer is null.  Per
the comment, LOOKUP_RCU was added in kernel 2.6.38, and
this code is #ifdefed accordingly.
The fix is to test if nd is null in the LOOKUP_RCU check.

LU-3182 lmv: fix duplicate directory entries

In 4e57f6dd3a156e35ccb587fc5c003805dd73ecb7, I accidentally
introduced a new way for duplicate directory entries to be returned
from readdir().  That patch fails to properly decrement the nlupgs
counter when breaking out of the inner-for loop.  This accounting
error causes an extra iteration of the inner-for loop when processing

LU-3420 scrub: trigger OI scrub properly

In osd_fid_lookup(), if the iget() cannot locate the backend inode
(return -ENOENT or -ESTALE) with the found ino#/gen in the OI file,
there may be three cases:

1) MDT file-level backup/restore caused the OI invalid.
2) Someone unlinked the object but NOT removed the OI mapping, such
   as mount target device as ldiskfs, and modify something directly.
3) Someone just removed the object between the osd_oi_lookup() and
   the iget(). It is normal.

Under such case we can lookup OI again to check whether related OI
mapping is still there or not. If not, it is 3rd case. Otherwise,
it is diffcult to distinguish the 2nd from the 1st case. Relatively
speaking, the 1st case is more common than the 2nd case, so trigger
OI scrub without further distinguish.

To reduce the 2nd case, the initial OI scrub will scan the local
objects set to remove those stale OI mappings, such as the entry
for "CATALOGS" after file-level backup/restore.

Another update is about mapping FID to inode for the object with
remote name entry. For example, dir1's name entry resides on the
MDT0. Its object resides on the MDT1. On the MDT1, do file-level
backup/resotre. And before the OI scrub finishing to rebuilt the
OI files on the MDT1, MDT0 send RPC to MDT1 to access dir1's obj
with dir1's FID. On the MDT1, the OI mapping for FID1 is invalid
yet. Under such case, we have two possible solutions:

a) The MDT1 returns -EINPROGRESS to the MDT0, and the MDT0 retry
   such RPC sometime later.

b) On the MDT1, There is the directory "/REMOTE_PARENT_DIR" hold
   all the objects which have remote name entries on other MDTs.
   The object name under the "/REMOTE_PARENT_DIR" is FID string.
   So when get invalid OI mapping, OSD can localte the inode via
   lookup the "/REMOTE_PARENT_DIR" with the given FID.

Compared the two solutions, a) will cause the MDT0 busy wait until
related OI mapping rebuilt. b) is relative better. And bacause the
MDT file-level backup/restore is rare case, it will not affect the
normal cases for FID to inode mapping.

In fact, from the OSD view, it does not know whether the object for
the given FID is referenced by some remote name entry or not, and
especially for DNE II, a multiple-linked object may have many name
entries reside on many MDTs.

LU-2901 mdt: duplicate link names in directory

When creating a hard link to a file, the MDT/MDD/OSD code does
not verify whether the target link name already exists in the
directory.  The ZFS ZAP code checks for duplicate entries. The
add_dirent_to_buf() function in ldiskfs only checks entries for
duplicates while it is traversing the leaf block looking for free
space.  Even if it scanned the whole leaf block, this would not
work for non-htree directories since there is no guarantee that
the name is being inserted into the same leaf block.

To fix this, link should check target object doesn't exist as
other creat operations.

Add sanity.sh test_31o with multiple threads racing to link a new
name into the directory, while ensuring that there is a free entry
in the leaf block that is large enough to hold the duplicate name.
This needs to be racy, because otherwise the client VFS will see
the existing name and not send the RPC to the MDS, hiding the bug.

Add DLDLMRES/PLDLMRES macros for printing the whole lock resource
name (including the name hash) in LDLM_DEBUG() messages in a format
similar to DFID/PFID so they can be found in debug logs more easily.

LU-2335 build: stop checking for XATTR_ACL_SIZE

posix_acl_xattr_size() never changed in all kernels, liblustre
also implements the same as in kernel.
So XATTR_ACL_SIZE can be calculated at compile time and doesn't
need to be checked.

Removing it can reduce parameters that need to exist in Kconfig.

LU-2335 kernel: add CONFIG_ prefix to config values

Kernel uses CONFIG_ prefix for all values that comes from
Kconfig. So do the same for Lustre.

Rename OBD_MAX_IOCTL_BUFFER to CONFIG_LUSTRE_OBD_MAX_IOCTL_BUFFER,
LNET_MAX_PAYLOAD to CONFIG_LNET_MAX_PAYLOAD, and INVARIANT_CHECK
to CONFIG_LUSTRE_DEBUG_EXPENSIVE_CHECK.
