LU-3683 libcfs: improve validity test for valid file descriptors

File descriptor members of struct lustre_kernelcomm aren't set to
anything special at start time.
This leads to incorrect tests and skipping valid fd closes at stop time.
Fixed by defining, setting, and testing against a specific LK_NOFD value.

LU-3648 test: large_xattr_enable doesn't detect large xattrs

The large_xattr_enable function looks for "large_xattr" from
the output of dumpe2fs to determine if large xattrs is
enabled. When large extended attributes are enabled, the file
system flag "ea_inode" is set and not "large_xattr".

Since "large_xattr" may be used in the future for this
attribute, the fix is to grep for both "ea_inode" and
"large_xattr".

LU-3556 osd-ldiskfs: remove dependency on mdd module

Move the lu_capainfo_get() function (formerly named md_capainfo())
into obdclass/capa.c instead of mdd_device.c.  Otherwise, the
osd-ldiskfs.ko module depends on mdd.ko in order to load, and that
doesn't really make sense.

Move the lu_capainfo structure (formerly named md_capainfo) into
lustre_capa.h, and change the structure field prefix to match the
new name.  Fix up the users of this structure/function, and do some
code style cleanup in those functions at the same time.

Move the mdt_set_capainfo() and mdt_dump_capainfo() structures from
being static inline in mdt_internal.h into mdt_lib.c, since they are
too big to be static inline functions.  mdt_dump_capainfo() isn't
used anywhere, so it is put under #ifdef DEBUG_CAPA.  They should
really be named mdt_capainfo_{set,dump}(), but that was too big a
change for this patch.

LU-3462 build: Repair "make dist"

The "make dist" target should assemble a canonical tarball of the
lustre source tree.  Generally speaking, it should not be effected
by command line options given to the configure script.

For instance, all source files should appear in the tarball regardless
of whether or "--disable-server" is engadged.  Some recent LU-1330
landings have broken this by making compilation of some source files
optional, but failing to add those optional source files to EXTRA_DIST.

LU-1606 idl: remove LASSERT/CLASSERT from lustre_idl.h

Remove the usage of LASSERT() and CLASSERT() from lustre_idl.h, so
that it is usable from userspace programs if needed.  These have
crept in over the years, but are not intended to be there.

The CLASSERT() checks for fid swabbing were largely redundant, and
have been moved to lustre/fid/fid_handler.c.

The fid_is_sane() macro has been modified to remove the check that
f_ver == 0, since this will eventually not be true, and the client
or server should not crash if it sees such a FID during usage.

There are still a few LASSERTs that need to be removed when FID-on-OST
is landed, but I don't want to remove them before that code lands.

There are also uses of CERROR() that could be removed at that time.

LU-3486 llite: remove ll_d_root_ops

Mnt root dentry will never be revalidated, but its d_op->d_compare
will be called for its children, to simplify code, we use the same
ll_d_ops as normal dentries.
But its attribute may be invalid before access, this won't cause
any issue because it always exists, and the only operation depends
on its attribute is .permission, which has revalidated it in lustre
code.

So it's okay to remove ll_d_root_ops, and remove unnecessary checks
in lookup/revalidate/statahead.

This patch also includes several small fixes:
* don't d_add() for create only files, because the dentry is fake,
  and will be released right after use.
* alloc ll_dentry_data may fail, add check for this.

LU-3641 libcfs: Zero fill shrinker struct in cfs_set_shrinker

Dropping Lustre caches might not terminate if the Linux kernel
supports the customisable shrinker batch size feature (commit
e9299f5058595a655c3b207cda9635e28b9197e6). This kernel feature
added a new field (batch) to the shrinker struct. Lustre does
not initialize it. When the unitialized batch value is negative,
the kernel shrink_slab function never terminates its loop that
calls the Lustre shrinker function. The problem was observed
with the ldlm_pools_cli_shrink shrinker, but it could also happen
with other Lustre shrinkers.

The fix is to ensure that all fields of the shrinker struct are
initialized by zero filling the struct when cfs_set_shrinker
allocates it. Zero filling works with all versions of the kernel.

LU-3223 utils: multiple args for path2fid/fid2path

Allow "lfs path2fid" to process multiple pathname arguments on
the command-line.  Like "grep" with multiple filenames, it will
print "filename: " at the beginning of the line when processing
multiple files.

Allow "lfd fid2path" to process multiple FID arguments on the
command-line.  All of the pathnames will be printed for each FID,
or can be limited to a single pathname per FID via "--link 0".

Add basic sanity tests for path2fid and fid2path, along with
tests of the multiple-argument options for each command.

LU-3544 nfs: writing to new files will return ENOENT

This happend with SLES11SP2 Lustre client, which in turn acts as an
NFS server, exporting a subtree of an Lustre fs through NFS.

We detected that whenever we are writing to a new file using, fx,
'echo blah > newfile', it will return ENOENT error. We found
out that this was caused by the anonymous dentry. In SLESS11SP2,
anonymous dentries are assigned '/' as the name, instead of an
empty string. When MDT handles the intent_open call, it will look
up the obj by the name if it is not an empty string, and thus
couldn't find it.

As MDS_OPEN_BY_FID is always set on this request, we never need
to send the name in this request.  The fid is already available
and should be used in case the file has been renamed.
