Since NFS4 sever does not provide such services client manages its own mapping
between ino_t and filehandles.

Additionally PUTFH support is added to both RequestBuilder and
ReplyInterpreter.

nfs4: No need to cast from enum to int

Currently supports only the following operations: ACCESS, GETATTR, GETFH
LOOKUP and PUTROOTFH.
