Is "ChooserContext" the right class name here? IIUC, this is the
storage/persistence system for bluetooth permissions, while I'd expect a
"chooser context" to be the context in which a chooser appears: maybe the origin
or tab.

Renamed it to class BluetoothPermissionContext.

Done.

+ public:
+  explicit BluetoothChooserContext(Profile* profile);
+  ~BluetoothChooserContext() override;

+  // Grants |requesting_origin| access to the Bluetooth device known as
+  // |device_id|.

We also need to store the set of allowed service UUIDs for each origin and
device.
https://codereview.chromium.org/1502663003/diff/100001/content/browser/blueto...
starts recording this set, but you can record an empty set for now, just so
there's space for it.

"known as |device_id|" doesn't really tell us which ID you're using. Specify
that it's either BluetoothDevice::GetIdentifier() or
BluetoothDevice::GetAddress(). (It's probably the address, since that's what the
rest of the system uses for now.)

[juncai, 2016/01/11 21:55:16]

Done.

Done.

This'll probably need to return the set of services.
