This adds support for the KSZ8081 ethernet phy.
Only the IDF 4+ specific code is modified, as the phy support was only
added recently:
espressif/esp-idf@aecfbf96
This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

This enables customizing HTTP headers which adds some extra flexibility.
This does not break anything of course because this change introduces a new constructor with a new additional HTTPClient argument for HTTPUpdate class.
In some use cases getting rssi signal from one channel is more stable (less variance) than rssi from the three advertising channels.
This change allows you to specify which channels are used to advertise.
In case you have multiple APs with the same SSID/password and WiFi.begin(ssid, pwd) is called, ESP32 defaults to connect to THE FIRST AP FOUND matching ssid - according to:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/network/esp_wifi.html#_CPPv418wifi_scan_method_t
This can cause situations that ESP32 is trying to connect to AP which is far away from it (weak signal) even there is AP close to it, just as in my house - I have AP on channel 6 which is in the 1st floor (quite far from room where I do the programming) and AP on channel 13 in the same room I do the programming (which is in the 2nd floor) - result: ESP32 is trying to connect to the AP on channel 6 because it finds it first and never try the AP on channel 13 in the same room, result of this is very unreliable WiFi connection.
When scan_method is set to WIFI_ALL_CHANNEL_SCAN, ESP32 scans all channels and choose the nearest / strongest AP (matching the ssid of course) as expected - result is no connection problems at all.
Therefore I propose adding this parameter into WiFi.begin, connection problems as described above are quite confusing (especially for beginners), I can imagine that for example Schools there are usually using mutliple APs and this can cause intermittent connection problems without obvious reason.
Fixes: #4884
* Use HTTP method table from ESP-IDF's nghttp
* Parse methods using IDF's HTTP method list
* Make example's loops to allow the CPU to switch tasks
- File might not eval to false if opened with write/append and SD is gone
- Allow card to be formatted if FAT partition was not found
- Mark card as gone in certain situations
- Fix several logic errors in low level SD API
mbedTLS requires repeated calls to mbedtls_ssl_write() whenever it returns MBEDTLS_ERR_SSL_WANT_READ or MBEDTLS_ERR_SSL_WANT_WRITE. this happens when the client sends data faster then the server or the connection can handle.
- Remove client from the list of devices in case registration fails
- Filter other events not related to registration during registration phase
- Cleanup if connect fails
- Reset if after disconnect
- Disconnect callback *after* cleanup is done so object can be deleted
This fixes some of the issues I had like:
- `BLEClient::connect` hangs up and never recovered because registration failed
- `BLEClient` could not be deleted after disconnect or deletion creating ghost events https://github.com/espressif/arduino-esp32/issues/4047
- `BLEClient` could not be properly reused after a connection was attempted (successful or not)
* Cleanup in case of registration and connect failure.
Cleanup before calling disconnect callback for safe delete.
Reject other events during registration.
Adresses #4047, #4055
* Clear if after unregister #4047
fixes#4596
* Prevent possible undefined behaviour by get methods not taking an index as parameter
* Add methods to get the count of service data UUIDs and service UUIDs
* Various code improvements
* Speed up upload by a factor of 17
Uploads are very slow because of an unnecessary "client.connected()" check in _uploadReadByte().
Here is what happens:
client.connected() is called for every byte read. WiFiClient::connected() calls recv(fd(), &dummy, 0, MSG_DONTWAIT); which takes a relatively long time, so the optimized path of returning a buffered byte via client.read() is effectively nullified.
Removing the one line changed the upload speed for a 2 MB file (discarding the received data) from 22 KB/sec (before) to 367 KB/sec (after).
The change is safe in the face of disconnects because client.read(), when it no longer has buffered data, calls (WiFiClient) fillBuffer(), which calls recv(), so the disconnection will be detected in due course.
* Move disconnect check into the timeout loop
