Before fixing, the tx power in adv data is always 0xeb(-21dbm).
restriction:
If change BLE advertising TX power, please call esp_ble_gap_config_adv_data()
after BLE adv TX power changed.
Later, will implement set BLE advertising TX power via HCI, then the
TX power value in adv data can be update automatically after BLE adv
TX power changed.
AVRCP connection binds to A2DP in current implementation, despite the two profiles are\
independent according to specification. AVRCP connection is not necessary to set-up \
if A2DP connection fails to establish
In opening state of AVDTP connection, if SDP client fails to get valid A2DP service record\
from peer SDP server, then do not initiate AVDTP connection request
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
As the bluedroid original implmentation of BR/EDR and BLE dual mode about discovery mode,
when set discovery mode for BR/EDR, it will stop ble advertising.

Problem:
The new API esp_bt_mem_release() that was added freed BTDM data to heap from esp_bt_controller_mem_release().
Now with the BT memory optimization commit ee787085f9,
the BTDM data is optimized and reduced to only 32 bytes which is not sufficient amount to be added to heap.
So, using the API leads to assert saying that the region is too small.
Solution:
Modify heap_caps_add_region_with_caps to return ESP_ERR_INVALID_SIZE in case the range is too small to create a new heap.
Do not assert if return value is ESP_ERR_INVALID_SIZE
This also fixes using API esp_bt_controller_mem_release() with ESP_BT_MODE_BTDM

res was declared as “bool” so expression
((count == 0) ? A2D_SET_ONE_BIT : A2D_SET_MULTL_BIT)
always evaluated to “true”, and was implicitly converted to
A2D_SET_ONE_BIT.
1. after memory release MR merged, due to the get acl number condition is not completed, it will cause get acl number value incorrect
2. It may cause set Security Mode (BR/EDR) enable failed
Multiple modules register their callback BTA_GATTS_AppRegister().
If any of the callbacks do not free the allocated pointer in
BTA_GATTS_CONF_EVT event, then this can result in memory leak.
So, free the pointer after the callback function is called and remove
the calls to free in the callback functions as it is now not required
