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.

Since user space has its own filtering of small RSSI changes sending a 0 value will essentially force user space to wake up the higher layers (e.g. over D-Bus) even though the RSSI didn't actually change more than the threshold value. This patch adds storing also of the RSSI for pending advertising reports so that we report an as accurate RSSI as possible when we have to send out the stored information to user space.
