These properties are read on Bluetooth stack startup only and require stack
restart if changed. All customization properties names start with
-"persist.sys.bluetooth." or "ro.bluerooth." followed by specific HAL name e.g.
+"persist.sys.bluetooth." or "ro.bluetooth." followed by specific HAL name e.g.
"persist.sys.bluetooth.handsfree". If both are present "persist.sys.bluetooth."
takes precedence. This allows for read only properties to be set during build
leaving enough flexibility for developing or debugging purposes.
