Pass a pointer to the length to the OID get/set routines.

An OID get request may return less data than requested; pass a pointer
to the length to pcap_oid_get_request(), so that it can supply the
amount of data actually supplied.  It also appears that a set request
may copy less data than supplied, so do the same for
pcap_oid_set_request().
