DBTAdapter: Make HCIHandler instance aggregated (lifecycle over full adapter lifecycle)

Since HCIHandler is being used to track all connections (direct or whitelisted),
it is essential to have it running over the whole adapter lifecycle.

openHCI() is now being performed within validateDevInfo(),
hence also sets adapter's valid state.

Call newly added checkValid() in user API on most 'action' methods,
throws exception if adapter is in invalid state.
