To avoid too many events being sent to user space and to help parsing of all available remote device data it makes sense for us to wait for the scan response and send a single merged Device Found event to user space. This patch adds a few new variables to hci_dev to track the last received ADV_IND/ADV_SCAN_IND, i.e. those which will cause a SCAN_REQ to be send in the case of active scanning. When the SCAN_RSP is received the pending data is passed together with the SCAN_RSP to the mgmt_device_found function which takes care of merging them into a single Device Found event. We also need a bit of extra logic to handle situations where we don't receive a SCAN_RSP after caching some data. In such a scenario we simply have to send out the pending data as it is and then operate on the new report as if there was no pending data. We also need to send out any pending data when scanning stops as well as ensure that the storage is empty at the start of a new active scanning session. These both cases are covered by the update to the hci_cc_le_set_scan_enable function in this patch.
