[RFC 01/16] Add discovery callbacks to btd_adapter_ops

[Andre Guedes <andre.guedes@openbossa.org>]

This patch adds start_discovery and stop_discovery callbacks to
struct btd_adapter_ops. These callbacks are responsible for starting
and stoping the discovery procedure. It also creates dummy functions
in hciops and mgmtops which implements those callbacks.
