epicmtd: Update WiMAX for newer API

-Decompile using a combination of JD and CFR
-Fix compatibility with KK by modifying DhcpHandler
   to translate between new DhcpResults object and old
   DhcpInfoInternal object, which is used heavily
   throughout WimaxStateTracker
-Enable debug logging throughout the various classes
-Modify retry interval for failed connects / reconnecting,
   making it more aggressive and reconnect sooner.
-Add missing methods to completely implement a NetworkStateTracker
-Stop listening for tethering enabled intent, so Wimax
   doesn't disconnect and reconnect in a "Backhaul" mode
-Fixed issue where multiple connect/disconnect notifications
   were being displayed
-Properly communicate with ConnectivityService to integrate
   with the rest of Android's networking. This does a few things:
   - Fixes WiFi tethering
   - Allows 3G to be torn down when Wimax connects, instead of
       just staying connected unused alongside Wimax
   - Integrates it with the rest of Android. Before it was kind
       of a standalone daemon that acted independently of what
       the rest of Android was doing.
