NFS: add XDR decoder for mountd version 3 auth-flavor lists
Introduce an xdr_stream-based XDR decoder that can unpack the auth-
flavor list returned in a MNT3 reply.
The nfs_mount() function's caller allocates an array, and passes the
size and a pointer to it. The decoder decodes all the flavors it can
into the array, and returns the number of decoded flavors.
If the caller is not interested in the auth flavors, it can pass a
value of zero as the size of the pre-allocated array.
