Support for paths in export file

[ylangisc]

We use the following export file:

exports = new ExportFile(new StringReader("/ *(rw,no_root_squash,acl)"));

and mount the NFS v41 server with

mount -t nfs -o vers=4,port=_someport_ nfs4jserverhost:/ /volumes/mynfs

This works perfectly fine but we would like to export a non root path, i.e.

exports = new ExportFile(new StringReader("/myexport *(rw,no_root_squash,acl)"));

Trying to mount with

mount -t nfs -o vers=4,port=_someport_ nfs4jserverhost:/myexport /volumes/mynfs

fails on my macOS with

mount_nfs: can't mount /myexport from localhost onto /volumes/mynfs: Permission denied
mount: /volumes/mynfs failed with 13

Can you please let me know if this is supported in NFS4j or not? Using the latter export on a Linux based NFS server let me mount the NFS share on my macOS with the command above without any issues.

Noticed that we do not correctly handle the initial lookup with the additional path in our NFS implementation. Seems to work now.
