The HFP spec uses a 16-bit integer for Features in SDP so I believe we
should too.

+

+			has been completed.  In the case of Handsfree this
+			means that BRSF exchange has been performed and

+

+			and notify the Endpoint using org.bluez.MediaEndpoint.
+

+
+				strict Device:
+
+					BlueZ remote device object.
+
+				string UUID:
+
+					Profile UUID of the connection.
+

+
+					Remote profile version.
+

+
+					Remote profile features.

Same thing here about the Features integer size.
