1. Adds bindings for getCharacteristics 2. Adds getCharacteristics function to public interface 3. Implements getCharacteristics from public interface 4. Adds necessary IPC messages 5. Modifies HeartRateService so that it has two Body Sensor Location characteristics. This way we can test what happens when two characteristics have the same UUID. Also modify the GetBaseGATTCharacteristic function to take an identifier. Before we just used the UUID but we need to change it now that multiple characteristics have the same UUID. 6. Adds LayoutTests. BUG=588876 Review URL: https://codereview.chromium.org/1723723002 Cr-Commit-Position: refs/heads/master@{#378001}
Bluetooth in Content
content/*/bluetooth implements Web Bluetooth using the
device/bluetooth code module.
Testing
Bluetooth layout tests in third_party/WebKit/LayoutTests/bluetooth/ rely on
fake Bluetooth implementation classes constructed in
content/shell/browser/layout_test/layout_test_bluetooth_adapter_provider.
These tests span JavaScript binding to the device/bluetooth API layer.
