esp-idf/components/bt/bluedroid/bta/gatt/bta_gattc_api.c
Yulong ece6bd9b82 component/bt: Change the btc gattc callback function with the compile error. 
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.
