In pevious implementation, A2DP sink will register an A2DP source Stream End Point(SEP) although the SEP is not\
supposed to be used. Now remove the unused SEP for source so that only one role of A2DP can be supported at one
time. Service record in local SDP server only includes at most one service for A2DP sink role or source
1. esp_ble_remove_bond_device will only remove BLE bond key and disconnect BLE device.
2. esp_bt_gap_remove_bond_device will only remove BT bond key and disconnect BT device.
A cherry-pick of MR !2562
1. Change all the hash used from the coap module to generated by the bluedroid module directly.
component/bt: Added the <string.h> include file to the gattc_co module to avoid compile error.
1. add the L1 include path with a prefix, such like osi/list.h, stack/a2d_api.h and etc.
2. modify component, only bluedroid/api/include/api is export to another component and application,
other include path just for bluedroid used
3. put bluedroid/include into common/include/common, so the root directory of bluedroid have no include path.
4. modify doxygen to use esp_bt.h and redirect to
component/bt/bluedroid/api/include/api/
fix compile
1. Change all the gattc API && bta gattc layer.
2. Debug the code and change the btc_ble_gattc_get_db method.
3. Change the gatt read API interface.
4. Reconstruction the BTA_gattc_cache code.
5. Change back the bluedroid_get_status to marco.
6. Change the gattc docs format.
7. Change the docs format.
8. fix the read char value bug.
9. change the gattc_get_attr_count method.
10. Change back the bta_gattc write ccc code.
11. Change the gattc api docs format
12. Change the gattc API docs.
13. Change the prepare write descriptor method to avoid the exection.
14. modify gatt clinet demo with new API
15. Change the p_src_data->read.p_value to avoid exection.
16. Change the bugfix of gattc unreg for the notify.
component/bt: Added the serch service res start_handle & end_handle to the result.
component/bt: Added the bta_gattc_cache_write when gatt discovery complete.
component/bt: Added the bta_gattc_cache_write declaration.
component/bt: Added the comments for esp_ble_gattc_cache_refresh API.
component/bt: Change the spelling errors & some comment error.
component/bt: fix bug of get gattc cache address list error.
1. Change the esp_bluedroid_get_status to macro;
2. added the malloc & free for the get_addr_list
component/bt: Added the addr_info->ass_addr == NULL Judgment to prevent crashes in the bta_gattc_co_cache_find_src_addr function.
component/bt: Fixed following gattc cache bugs
1. gattc can't refresh the gattc cache in the gatt discover state;
2. remove the nvs_get_blob in the cache address init function;
3. added the nvs_set_blob return value judgment in the cache address save function;
4. added the list_new when ass_address is NULL;
5. Change the ass_address list remove method to fix the ass address can't remove bug.
Bluedroid use a set of timer function pairs such as btu_start_timer/btu_stop_timer, btu_sys_start_timer/btu_sys_stop_timer for use, in a lack of timer release functions. Thus the timers may be exhausted after some event sequence such as repetition of connection/reconnection with different devices. The maximum timer number used in bluedroid is given by ALARM_CBS_NUM which is 30 for now. This bugfix borrowed some update from bluedroid in Andoroid 7.0, which add timer release functions which promote the recycle of timer resources.
component/bt: Added the Macro for the classic BT support.
component/bt: added the bluedroid deinit method.
component/bt: allow more classic BT global variables to use dynamic allocation scheme
1. allocate memory for AVDT, AVCT control blocks when dynamic memory is used
2. allow SBC decoder buffer to use dynamic allocation scheme
component/bt: Remove the wrong changes in bt/Kconfig & Added the GATTS_INCLUDED in the gatt_free function when gatt service close.
component/bt: Shorten the abbreviation BT_ALLOCATION_FROM_SPIRAM_FIRST and BT_BLE_DYNAMIC_ENV_MEMORY two macros.
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
1. optimiz the ble stop adv callback function.
2. added the osi_mutex_unlock in the bta_gattc_wait4_service_change_ccc_cback function when the p_timer_param == NULL || p_conn == NULL.
