Subject: [PATCH v1 1/3] monitor: add new Intel extended telemetry events

This patch adds new Intel extended telemetry events for both ACL and
SCO/eSCO audio link quality reports.

For SCO/eSCO audio link quality report, it shows something like

Subject: [PATCH v1 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.

Not sure where you get the idea of adding a series-prefix, usually the
prefix should come in the subject e.g PATCH BlueZ which you can
automatically do by adding the following to your .git/config:

[format]
subjectprefix = PATCH BlueZ
