This patch add the documentation of the Battery Provider which lets
external clients feed battery information to BlueZ if they are able to
decode battery reporting via any profile. BlueZ UI clients can then use
the org.bluez.Battery1 API as a single source of battery information
coming from many different profiles.

+==================================
+A battery provider starts by registering itself as a battery provider with the
+RegisterBatteryProvider method passing an object path as the provider ID. Then,
+it can start exposing org.bluez.BatteryProvider1 objects having the path
+starting with the given provider ID. It can also remove objects at any time.
+BlueZ will stop monitoring these exposed and removed objects after
+UnregisterBatteryProvider is called for that provider ID.

+Service org.bluez
+Interface org.bluez.BatteryProviderManager1 [experimental]
+Object path /org/bluez/{hci0,hci1,...}
+
+Methods void RegisterBatteryProvider(object provider)
+
+ This registers a battery provider. A registered
+ battery provider can then expose objects with
+ org.bluez.BatteryProvider1 interface described below.
+
+ void UnregisterBatteryProvider(object provider)
+
+ This unregisters a battery provider. After
+ unregistration, the BatteryProvider1 objects provided
+ by this client are ignored by BlueZ.
