This enable us to do passthrough equivalent security model on NFS directory.
NFS server mostly do root squashing and don't support xattr. Hence we cannot
use 'passthrough' or 'mapped' security model
Also added "mapped-xattr" security to indicate earlier "mapped" security model
Older name is still supported.
POSIX rules regarding ctime update on chmod are not followed by this security model.

To implement synthetic file system in Qemu we may not really
require file descriptor and Dir *. Make generic code use
V9fsFidOpenState instead.

A new fsdev parameter "readonly" is introduced to control accessing 9p export.
"readonly" can be used to specify the access type. By default "rw" access
is given to 9p export.

This patch use file system specific ioctl for getting i_generation
value. Not all file system support the ioctl. So we add an export
specific extended operation and assign right callback for the
file system that support i_generation ioctl
["M. Mohan Kumar" <mohan@in.ibm.com> we can do ioctl only for
regular files and directories on the server]

Current rpath inline function is heavily used in all system calls.
This function has a static buffer making it a non-thread safe function.
This patch introduces new thread-safe routine and makes use of it.
