In person we discussed and I thought you said the plan was a mojo interface each
for adapter, device, characteristic, descriptor? 

[ortuno, 2016/03/31 16:56:44]

Yes. That's the long term plan. Since that + mojo would be too much to refactor
at once, I started by only converting from IPC::Message to Mojo.

+
+  // Writes a value to the characteristic with
+  // |characteristic_instance_id|. The callback is run with
+  // WebBluetoothError::SUCCESS if the value was successfully
+  // written.
+  RemoteCharacteristicWriteValue(
+    string characteristic_instance_id,
+    array<uint8> value) => (WebBluetoothError error);
