Re-sending this patch, at Steve Dickson's request.

-- Henrique

--------------------------------------------------------------

Attaching path to exportfs that:
- in client.c/client_lookup:
    changes the (x)log level for unresolvable entries in
    /etc/exports from L_ERROR to L_WARNING,
- in hostname.c/host_addrinfo:
    changes the (x)log level for unresolvable entries in
    /etc/exports from D_GENERAL to D_PARSE,
- in export.c/export_read:
    counts the number of exported volume entries and
    generates a (x)log L_ERROR if no volumes are exported.

Built and tested on a Fedora 20 system.
