This is just a quick glance at all the header files exposed to the
users from cleanup point of view.

ee787085f9 component/bt : decrease memory consumption by conn number
1. BLE only with 9(max) connection will decrease 3K DRAM
2. BR/EDR only with 7(max) connection will decrease 16K DRAM
3. Any of BLE or BR/EDR connection number decrease will also decrease DRAM consumption
4. Decrease one BLE connection will save about 1KB DRAM
5. Decrease one BR/EDR ACL connection will save about 1.2KB DRAM
6. Decrease one BR/EDR SCO/eSCO will save 2KB DRAM.
7. fix some definition and kconfig
8. remove 1.2k of vhci tx cache and make .bss & .data to heap about 1.4K
9. modify BT Reserved Memory size and modify example to support new bt kconfig

f610249bdd Reclaim BT/BTDM BSS and Data in bluetooth memory release function
1. Modify esp_bt_controller_mem_release() to release BTDM BSS and Data to heap if
ESP_BT_MODE_BTDM mode is passed to it
2. Add a new API esp_bt_mem_release() which internally calls
esp_bt_controller_mem_release() with the provided mode and then if mode
is ESP_BT_MODE_BTDM, releases BT BSS and Data to heap.

Background:
For Wi-Fi and BT/BLE applications, for e.g. the usecase is like when
Bluetooth is used for provisioning and once the device is connected to the Wi-Fi
AP, we can turn off Bluetooth completely. In such scenarios, it should be possible to
reclaim all the memory of Bluetooth. Although, currently this does not
happen.

Experiment:
Made the following modifications to examples/bluetooth/gatt_server :
1. Added support of simple_wifi to it
2. Moved all the bluetooth related code under CONFIG_BT_ENABLED config
option
3. Calculated the free heap in 2 similar scenarios:
   i. Disabled BT (CONFIG_BT_ENABLED undefined) and checked the free
heap after STA connected
   ii. Kept BT enabled and disabled it after STA connected and checked
the free heap
Ideally, the numbers for i., ii. above should have been similar. But
there was a delta of almost 30-31K. (i. > ii.)
4. Through make size-components checked the common BSS for libbta.a and libbtdm_app.a
and found it to be almost 30K. Data is around 1K

Solution:
1. Modified the linker script to mark the BSS and Data for these libraries and
free it when ESP_BT_MODE_BTDM mode is passed to mem release APIs.
2. Verified that the free heap is comparable for i. and ii. above.

Note: It is known that once this is done, Bluetooth can only be used
again post reboot.

22e21b38f7 component/bt: implement bluetooth modem sleep mode, one mode for BLE only and another for dual mode bluetooth
1. provide options for bluetooth low power mode
2. provide two options for bluetooth low power clock: main XTAL and external 32kHz XTAL
3. provide function and callbacks to control bluetooth low power mode, including enable/disable sleep, software wakeup request, low power clock settings, check power state, etc
4. modify vhci API vhci_host_send_packet to use blocking mode
5. note that DFS and bluetooth modem sleep can not be used together currently.

65bdb2d7ff component/bt : fix btdm mem release cause 0x3ffbbb28-0x3ffbdb28 add to region but should not.
1. fix the bug. Modify the condition that esp_bt_controller_mem_release() shoud be only called before esp_bt_controller_init() or after esp_bt_controller_deinit()
2. modify the example to use esp_bt_controller_mem_release()

b936441b9b Startup flow refactoring
This change removes implicit WiFi/BT initialization from startup code.
"main" task is started once essential part of startup code is complete.
This task calls application-provided "int main(void)" function, which can call WiFi/BT init functions if necessary.
