Changing readdir calls to readdirp calls to handle layout issues
seen in dht.
Also, changing posix readdir call to do stat after dir read for readdirp.

* in dht_lookup_dir_cbk(), at the entry itself we are dereferencing
local->inode, which can be NULL in many cases. Hence no need to
check/dereference that variable. Just check 'local->gfid'.

* If the errno is ESTALE for root, fuse doesn't send fresh lookup on
the path (it does for all other inodes). Earlier layout mismatch for
root never used to happen inside codebase, and if noticed, it was
serious issue.
Now with DVM, after a add-brick or a remove-brick, layout can be
changed even for 'root' inode. Needed to fix this issue inside
distribute itself, instead of fuse sending 'fresh' lookup on root.

* this was the root cause for having layout mismatches in case of
add-brick, because the gfid of directories on newly added brick
was always mismatching, which caused many operation on that

Usage: "glusterfs-defrag <MOUNTPOINT>"
there are new features added to distribute with this patch:
* bash# getfattr -n trusted.distribute.linkinfo <file>
Gives output in the format "<hostname>:<directory>", if there is a
linkfile present, where hostname is server, directory is backend
directory where the actual linkfile is present.
* bash# getfattr -n trusted.glusterfs.pathinfo <path>
Gives layout information if directory, and info about actual
location of file in backend servers, in the form of
'hostname:directory'. (TODO: should extend it to all xlators)
* bash# getfattr -n trusted.distribute.fix.layout <path>
scales out the directory layout in distribute, so when new
servers are added, layouts are fixed to include them.
* removed 'scale-n-defrag.sh' as its no more required.
* changed 'defrag.sh' to have a feature to specify target bricks,
so defrag happens to only those nodes. moved the file to
'glusterfs-defrag', which now gets installed to '${prefix}/bin'
* storage/posix:
takes new option 'hostname' so it can resolve to same hostname
given during 'gluster volume create'.
with 'trusted.glusterfs.pathinfo' posix returns the value in
'hostname:real_path' format.
