api: revise localhost function (#128)
* api: revise localhost function Revise getLocalHosts() so it doesn't report unwanted hosts. getLocalCnxType() is no longer needed. * include new iplookup function too * incorporate Eric r1de values for getCurrentNeighbors * use alternative for mac2host() * get actual wlan interface for arp query * tested on dualband radio Tested on dualband radios with active clients on both Mesh RF and Wifi AP. * add more error checking * fix iplookup match It is possible to have 2-digit "mid" prefixes. Fixes match to account for 2 possible digits. * tighten up code * add extra info values for Eric r1de
