gNFS: Subdir mount does not work on UDP proto
After enabling nfs.mount-udp, mounting a subdir on a volume over
NFS fails. Because mountudpproc3_mnt_3_svc() invokes nfs3_rootfh()
which internally calls mnt3_mntpath_to_export() to resolve the
mount path. mnt3_mntpath_to_export() just works if the mount path
requested is volume itself. It is not able to resolve, if the path
is a subdir inside the volume.
MOUNT over TCP uses mnt3_find_export() to resolve subdir path but
UDP can't use this routine because mnt3_find_export() needs the
req data (of type rpcsvc_request_t) and it's available only for
TCP version of RPC.
FIX:
(1) Use syncop_lookup() framework to resolve the MOUNT PATH by
breaking it into components and resolve component-by-component.
i.e. glfs_resolve_at () API from libgfapi shared object.
(2) If MOUNT PATH is subdir, then make sure subdir export is not
disabled.
(3) Add auth mechanism to respect nfs.rpc-auth-allow/reject and
subdir auth i.e. nfs.export-dir
(4) Enhanced error handling for MOUNT over UDP
