Implement just enough for MOUNT and stat!

Adding a bunch of the "handle" (fh3 for this) processing functions as well as
the basic GETATTR3 implementation. This revealed that attrmask_t has a clumsy
additional ATTR_RDATTR_ERR bit to say "Hey, let me know if there was an error",
so we have to handle both ATTRS_NFS3 *and* that one.

Now our three hop proxy does a thing!

ganesha-client => ganesha-proxy (192.168.1.2) => nfsd
