Subject: [BlueZ PATCH v4 2/3] adapter: read quality report feature

This patch adds a new UUID for the quality report experimental
feature. When reading the experimental features, it checks if
the new feature is supported by the controller and stores the
value in the quality_report_supported flag of the adapter.

The quality_report_supported flag could be used by the bluetoothd
to determine if the quality report feature can be enabled.
