Android is interested in all of the Scan Responses. Also the ones which
are set as non discoverable. It is in order to support
Observer\Broadcaster mode. Therefore discoverable flag can be removed
from the device found callback. This patch does it.

This patch is now applied, thanks.
Second needs to be rebased.

GATT is interested in advertising event type. i.e if it is connectable
or not. It is because GATT does not want to triggers connection to
devices doing non-connectable advertising.
This patch add such support.
