1. remove the feature mask parameter from AVRC connection state event, as the AVCTP connection can be initiated by remote device before service discovery to remote device is performed. \ In this case, AVRCP connection state event may not be reported after connection initated by remote device is established. 2. remove ESP_AVRC_CT_MAX_EVT 3. add more documentations to AVRC APIs
