Log:
- Introduce a new macro, since that's what nfs loves, called
nfsm_srvpathsiz. This macro plucks a length out of an rpc request and
verifies that its size does not exceed NFS_MAXPATHLEN. If it does
it generates an ENAMETOOLONG response.
- Use this macro, and the existing nfsm_srvnamsiz macro in two places
where we deal with paths passed in by the client.
This fixes a linux interoperability bug. Linux was sending oversized path
components which would cause us to ignore the request all together. This
causes linux to hang indefinitly while it waits for a response. This
could still happen in other cases where we error out with EBADRPC.
