-------------------------------------------------

NFSv4 attribute and Readdir modifications:
* "dissect_nfs4_attribute()" was eliminated because the values dissection
portion of that routine was identical to the "dissect_nfs_attributes()"
routine. The code in "dissect_nfs4_bitmap4()" and
"dissect_nfs4_attrlist4()" was also similar so those routines
were also eliminated and their code incorporated in dissect_nfs_fattr4s().
These measures have reduced the size of 'packet-nfs.c' by almost 400 lines.
* Attributes were relabeled according to RFC 5661 (NFS4v1).
o “mand_attr” (REQUIRED attribute) header was changed to "reqd_attr”.
o “recc_attr” (RECOMMENDED attributes) header was changed to “reco_attr”
because "recommended" only has one ‘c’. =)
* In order to be able to list the attribute names horizontally in the
"Attr mask[x]" header (e.g., "Attr mask[0]: 0x0010111a (TYPE, CHANGE, SIZE,
FSID, ACL, FILEID)", “FATTR4_” was removed from the attribute names
(e.g., “FATTR4_TYPE (1)” is now “TYPE (1)”. Note that RFC 5661 does not
define them with a “FATTR4” prefix.
* In GETATTR responses, the “resok4” and “obj_attributes” subtrees were
eliminated because they are neither actual fields nor serve any practical
purpose.
* The READDIR "Directory Listing" subtree was reformatted. "Filename" was
changed to "Entry" because entries can also be directories.
"Value Follows", "cookie", and "Attr mask[n]" were moved within each entry.
If an Entry header is left-clicked all the fields of that entry are
highlighted in the Hex pane. If it is right-clicked the 'nfs.name'
field (filter) can be obtained. Finally, the "attr_vals:<DATA>" (text)
subtree was eliminated because it appears to serve no useful purpose and
clutters the tree.
