registered OUIs from manuf and allow custom dissectors for
Organizationally Specific TLVs. Fixes bug 7080.
Use uint_get_manuf_name() and uint_get_manuf_name_if_known(), rather
than tvb_get_manuf_name() and tvb_get_manuf_name_if_known(), in cases
where we've fetched the OUI.
Have the ECP/VDP dissector also display registered OUIs from manuf.
Get rid of the OUI_CISCO_2 OUI from tlv_oui_subtype_vals, as that can
come from the manuf file. Leave in comments explaining why, for now, we
aren't using the manuf file for *all* the OUIs.
