1. Add more notification events to the enum according to the event list in AVRCP specification.
2. Add API and callback events for basic AVRCP target functionalities to do init, deinit, callback-registration, connection status indication.
3. Implement API to set/get supported PASSTHROUGH command on local AVRCP TG, implement callback events for remote passthrough command indication.
4. Implement API to set/get supported notification eventIDs on local AVRCP TG, implement API to send event notifications to remote CT. \
Currently supported event in TG only includes ESP_AVRC_RN_VOLUME_CHANGE(0xd), which can be extended in later commits.
5. Implement callback events for SetAbsoluteVolume command indication on TG.
6. Add limitation of event_ids supported in RegisterNotification command in CT. The supported event_ids include: \
ESP_AVRC_RN_PLAY_STATUS_CHANGE(0x1), ESP_AVRC_RN_TRACK_CHANGE(0x2), ESP_AVRC_RN_PLAY_POS_CHANGE(0x5), ESP_AVRC_RN_VOLUME_CHANGE(0xd).
7. Add feature bit mask in parameter of callback event ESP_AVRC_CT_REMOTE_FEATURES_EVT for peer feature information got from SDP.
8. Add API and callback event to AVRCP CT to retrieve remote TG's supported notification event capabilities.
9. Modify data type for parameter of callback event ESP_AVRC_CT_CHANGE_NOTIFY_EVT.
10. Change AVRCP version from 1.3 to 1.4 for compatibility cause in using AbsoluteVolume feature.
11. Modify local AVRCP device to be category 1 as CT and category 2 as TG that applies to bluetooth headphones or speakers.
12. Update the use of AVRCP APIs and events in the two examples: a2dp_sink and a2dp_gatts_coex, which include the demo of volume control and notification.
stdatomic.h is available both in newlib and GCC include directories.
Normally (if you invoke the compiler without any flags) GCC include
directories are first on the list, so GCC’s stdatomic.h is used. In
IDF, we used to pass newlib include path as an extra include
directory, so newlib’s stdint.h got included instead.
Newlib 2.2.0 stdatomic implementation is compatible with -std=gnu99
but incompatible with -std=gnu11. And GCC doesn’t support atomic_load
with -std=gnu99 (it’s a C11 feature). So when we used atomic_load
with -std=gnu99, it worked due to newlib’s header.
Since we are no longer going to be including newlib headers into IDF,
GCC stdatomic will be used instead. Hence, add -std=gnu11 for source
files which use atomic features.
Operation:
In `esp_http_client_set_url`, we check for if old_host is same as new_host.
Delete and open new connection if host is different.
Issue:
We just pointed `client->connection_info.host` to `old_host` and reassigned it.
This made old_host and new_host always point to same location and hence, using old_host with new request.
Fix:
Made a separate copy for old_host using strdup.

Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
1. remove redundant SPI clock settings, use rom functions to set clock.
2. remove redundant SPI cs setup and hold settings.
3. for old 32Mbit psram, cs hold time must only be 0.5T due to the special driving mode.(cs_setup = 0; cs_hold = 0)
4. for new 64Mbit psram, cs hold time is recommended to be 2.5T. (cs_setup = 1, cs_setup_time = 0;cs_hold = 1, cs_hold_time = 1)
esp_wifi: fix the bug that no TBTT will be generated anymore after receiving wrong beacon when WiFi and BT coexist.
Closes IDF-589

1. Pass the correct conn_id to protocomm_req_handle
In transport_simple_ble_write(), passing param->exec_write.conn_id would
be invalid. Instead param->write.conn_id should be passed
Similar change in transport_simple_ble_exec_write() to use
param->exec_write.conn_id
2. simple_ble_start() assumes that the mode is BLE only and enables
Bluetooth controller accordingly. For, cases having BT + BLE like Alexa
(Provisioning over BLE + Audio over classic BT), this assumption should
be removed.
