adb: create autopoll variables directly within ADBBusState

Browse source 
Rather than each ADB implementation requiring its own functions to manage
autopoll state, timers, and autopoll masks prepare to move this information
directly into ADBBusState.

Add external functions within adb.h to allow each ADB implementation to
manage the new autopoll variables.
