dbced75b48 esp32/network_wlan: Wait for STA/AP START/STOP event in wlan.active.
This is a fix for commit bccbaa92b1:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
  interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
  interface is set active(True) and it was previously inactive, ie. not
  only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

Fixes issue #11910.

e4650125b8 esp32: Update port to support IDF v5.0.2.
This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also
cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3,
and C3).

Support for IDF v4 is dropped because it's a lot of effort to maintain both
versions at the same time.

The following components have been verified to work on the various SoCs:

53cb073571 esp32,esp8266: Change network.WLAN from a function to a type.
When the network module was first introduced in the esp8266 port in
ee3fec3167 there was only one interface (STA)
and, to save flash, the WLAN object was aliased to the network module,
which had just static methods for WLAN operations.  This was subsequently
changed in 9e8396accb when the AP interface
was introduced, and the WLAN object became a true class.

But, network.WLAN remained a function that returned either the STA or AP
object and was never upgraded to the type itself.  This scheme was then
copied over to the esp32 port when it was first introduced.

This commit changes network.WLAN from a function to a reference to the WLAN
type.  This makes it consistent with other ports and network objects, and
allows accessing constants of network.WLAN without creating an instance.

1093dea709 esp32,esp8266: Add support to set/get power saving mode of WLAN.
For esp32 and esp8266 this commit adds:
- a 'pm' option to WLAN.config() to set/get the wifi power saving mode; and
- PM_NONE, PM_PERFORMANCE and PM_POWERSAVE constants to the WLAN class.

This API should be general enough to use with all WLAN drivers.

Documentation is also added.

7fa322afb8 esp32,esp8266: Add support for the Espressif ESP-NOW protocol.
ESP-NOW is a proprietary wireless communication protocol which supports
connectionless communication between ESP32 and ESP8266 devices, using
vendor specific WiFi frames.  This commit adds support for this protocol
through a new `espnow` module.

This commit builds on original work done by @nickzoic, @shawwwn and with
contributions from @zoland.  Features include:
- Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO.
- Signal strength (RSSI) monitoring.
- Core support in `_espnow` C module, extended by `espnow.py` module.
- Asyncio support via `aioespnow.py` module (separate to this commit).
- Docs provided at `docs/library/espnow.rst`.

Methods available in espnow.ESPNow class are:
- active(True/False)
- config(): set rx buffer size, read timeout and tx rate
- recv()/irecv()/recvinto() to read incoming messages from peers
- send() to send messages to peer devices
- any() to test if a message is ready to read
- irq() to set callback for received messages
- stats() returns transfer stats:
    (tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts)
- add_peer(mac, ...) registers a peer before sending messages
- get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt)
- mod_peer(mac, ...) changes peer info parameters
- get_peers() returns all peer info tuples
- peers_table supports RSSI signal monitoring for received messages:
    {peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...}

ESP8266 is a pared down version of the ESP32 ESPNow support due to code
size restrictions and differences in the low-level API.  See docs for
details.

Also included is a test suite in tests/multi_espnow.  This tests basic
espnow data transfer, multiple transfers, various message sizes, encrypted
messages (pmk and lmk), and asyncio support.

Initial work is from https://github.com/micropython/micropython/pull/4115.
Initial import of code is from:
https://github.com/nickzoic/micropython/tree/espnow-4115.

eb51ca4a11 esp32: Use extmod/modnetwork.c instead of port-specific version.
Rather than duplicating the implementation of `network`, this allows ESP32
to use the shared one in extmod.  In particular this gains access to
network.hostname and network.country.

Set default hostnames for various ESP32 boards.

Other than adding these two methods and the change to the default hostname,
there is no other user-visible change.

d6bc34a13a esp32: Add a small delay before leaving wlan.active().
The delay is 1 ms. It avoids the crashes reported by the
issues #8289, #8792 and #9236 with esp-idf versions >= 4.2, but does
not solve an underlying problem in the esp-idf.

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.
