Fixed #7406 crash on WiFi STA_DISCONNECTED event with reason 0 (#7414)
Fixed #7406 . The "reason2str" macro in WiFiGeneric.cpp tries to read memory from index "-1"  in "system_event_reasons" array when handling STA_DISCONNECTED event with reason 0. Dealing with reason 0 as a reason 1 (WIFI_REASON_UNSPECIFIED) will solve the problem (the reason for this event to arrive with reason 0 is unknown). #7406

fall throughs or skipped field initializers.

Add proper comments for B64 cases to avoid GCC warnings

Fixes INADDR_NONE (#6659)
Description of Change

Fixes IPAddress INADDR_NONE declaration when using Arduino WiFi or ETH.
This symbol was defined as 0xffffffff by lwip /inet.h, making it impossible to use INADDR_NONE correctly.

This PR only works when <wifi-provisioning/wifi_config.h> has a modification to include <lwip/ip4_addr.h> instead of <lwip/inet.h>. This will be done directly to the sdk folder in the github structure and it has been fixed in IDF by a separated Merge Request. This will be reflected in the future, for good.

Tests scenarios

This PR was tested with all Arduino WiFi examples, including AsyncUDP. Also with ETH examples.
It was also tested for #6610 test cases.
Testing done for ESP32, ESP32-S2, ESP32-C3 and ESP32-S3.

Added another overloaded WiFiSTAClass::begin() function that provides… (#6398)
Summary

The examples demonstrate how to create a WPA2 Enterprise connection, but it requires using various direct esp_idf functions. This patch is intended to create another overloaded version of the WiFi.begin() function that allows a user to create a WPA2 Enterprise connection in much the same way as different kinds of connections.

My only question for the core maintainers is whether I should leave those #ifdef's in there. I added them so that it was easy to disable all the code I added via defines from my platformio.ini file, but they technically aren't necessary.

Impact

This should make it easier for novice users to create WPA2 Enterprise connections. For my university, I didn't need a root certificate or the client certificate or client key, so I haven't been able to debug those scenarios, but I built the begin functions to allow any one of those to be used, if needed.

I can confirm that eduroam-style WPA2 Enterprise networks that only require authentication with a username and password works as expected.

Reliability fix for autoReconnect when assoc_fail, autoReconnect did not work before for these failures.

Changes behavior of WIFI_REASON_ASSOC_FAIL event when autoReconnect is set, removes WIFI_REASON_ASSOC_FAIL/WL_CONNECT_FAILED so retry waitforconnectresult loop stays active for the retry, was not working before.

only use ksz8081 for idf versions later than 4.3 (this fixes compile as component for idf 4.3) (#5599)
esp_eth_phy_new_ksz8081 was added in IDF after version 4.3 and generates a compilation error with IDF-4.3. This change will only use esp_eth_phy_new_ksz8081 for IDF versions after 4.3

Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int… (#5509)
* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"

"The class Webserver is declared with two explicit constructors, one with signature:
WebServer::WebServer(IPAddress addr, int port)
Using this results in a server listening on the port number obtained by converting the value of the IPAddress addr argument (in host byte order) to a uint32_t and then to a uint16_t, which is manifestly not the result that would be expected.
...
As for a fix, we can assume from these results that this constructor is not being used and therefore could simply be deleted."

* Issue 5507
Reverse changes in commit bee1e7088cef913391155f096b42cd4bb89c5c6f after discussion.
Alternative fix to be done.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result"

This change adds support for multi-homed servers to libraries/WiFi.  It was assumed to be there already by libraries/WebServer, but was not.
This led to unexpected results when the IP address-specific constructor of class WebServer was used (see issue 5507).

This change was tested using three concurrent instances of WebServer, one bound to the WiFi station address, one bound to the WiFi soft AP address,
and one bound to INADDR_ANY.  See libraries/WebServer/examples/MultiHomedServers for the test method.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result" (cont.)
This fixes what I think might be the cause of CI failures on GitHub for the previous commit, namely the absence of an include file
in examples/MultiHomedServers.

* Fix issue #5507 "Constructor WebServer::WebServer(IPAddress addr, int port) produces an unexpected result" (cont.)

Change port numbers in examples/MultiHomedServers per pull-request comment from me-no-dev ...
"for this test to be valid, both servers should be on the same port. That is how you can make sure that the functionality works."

Increase default timeout for WiFiClient from 3ms to 3s (#5496)
## Summary
https://github.com/espressif/arduino-esp32/pull/5487 introduced a default timeout for WiFiClient, however the default was specified in milliseconds instead of seconds, see be84c8219c (commitcomment-54358731)
This 3ms timeout breaks OTA when the processor is busy.

## Impact
Sets the default to a saner value, fixes OTA.

[WiFiClient] Default connection timeout, when no timeout provided (#5487)
## The problem
WiFiClient's connect method variant where no timeout is passed can block esp32 MCU and may then cause watchdog to kick in and reset the device. This behavior is different from that, what is in arduino-esp8266 core.

## Summary
Some cross-esp libraries (working both on esp32 and 8266), like PubSubClient simply call connect method on WiFiClient, to get connected to remote server. However, connect behavior varies betwen esp arduino 8266 and esp arduino 32 cores. This pull request tries introduce same behavior - to make connect method non-blocking on esp32, like it is with 8266 arduino core.

## Proposed solution
Introduce default fixed timeout that can be changed by #define - by default set to 3 seconds.

### Affected components: 
WiFiClient

### Affected methods:
```c++ 
int connect(IPAddress ip, uint16_t port);
int connect(const char *host, uint16_t port);
```

### Impact
May impact projects or libraries using connect method variant without specified timeout, where:
- remote is located far away or
- connection is heavily limited, or
- remote is slow, when it comes to accept the connection
