nfs: add permission checking for mounting over WebNFS

Solaris 10 uses WebNFS and not the MOUNT protocol. All permission checks
for allowing/denying clients to mount are done through the MNT handlers.
These handlers will not give out a filehandle to the NFS-client when
mounting is denied. This prevents clients from successful mounting.
However, over WebNFS a well known 'root-filehandle' is used directly
with the NFSv3 protocol.

When WebNFS was used, no permission checks (the "nfs.export-dir" option)
were applied. Now the WebNFS mount-handler in Gluster/NFS calls the
mnt3_parse_dir_exports() function that takes care of the permission
checking.
