The logic can be simplified by using integer logic without a functional
change. Reduces code size by 40% (78 bytes -> 46 bytes) and silences
a Warith-conversion warning.
Converting floats to doubles is very expensive on esp8266, so prefer
calculations or comparisons as float. This saves 10% (20 bytes) of the
String::parseFloat() code size and probably quite a bit of runtime
overhead.
* CVE-2020-12638 workaround for WPA downgrade attack
When connected to an encrypted (WEP/WPA) router, a rogue packet can
cause the ESP8266 WiFi stack to drop to an unecrypted rogue network of
the same SSID.
Handle this by dropping the WiFi connection immediately and reconnecting
to the stored WPA/WEP network requested by the application, whenever the
AUTHMODE changes to OPEN from a secured mode.

This commit allows switching SDK firmware:
nonos-sdk-pre-v3 shipped with release 2.5.0 has issues:
* Some boards show erratic behavior (radio connection is quickly lost), with an unknown cause.
These boards work well with previous nonos-sdk-2.2.1 firmware (#5736)
* Overall performances seem to have decreased (#5513)
This PR restores sdk2.2.1 (as in core-2.4.2).
SDK-pre-3.0 - which has brought long awaited fixes (WiFi sleep modes) - is still available through a menu option available only with generic board.
BREAKING
* new define `-DNONOSDK221=1` or `-DNONOSDK3V0=1`
* for external build systems: new library directory: `tools/sdk/lib/<version>/lib`
* PIO: variable `PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK3` is needed for sdk-pre-v3.
Fix#5736
* weak hook early_setup() #2111#2133#2136
* rename to early_init (more "c" vs early_setup which is more "c++arduino")
* example
* improve earlyWiFi example, slightly change AddrList interface, move WiFi sketches into WiFi examples
* fix CI
* fix local CI runner
* fix local CI runner
* rename early_init() to preinit()
* + static ESP8266WiFiClass::preinit_wifi_off()
* update early disable wifi example

* fwupdate
* fw update to latest version:
WPA working, WEP+Open disabled by default. Need API change.
* helpers to follow sdk updates
* remove compare scripts - made a separate PR for them
* add wep api, restore original espressif comment (wep enabled does not prevent wpa)
* libmain was not up to date
* experimental: DTIM setting in WiFi.setSleepMode(WIFI_LIGHT/MODEM_SLEEP, DTIM-value)
with new getter: .getListenInterval() / .isSleepLevelMax()
* fixes
* fix debug message
* when not using listenInterval, set wifi sleep level to min
* update documentation
* update doc
* minimum changes for libraries to compile with lwip2
* add WiFiClient::availableForWrite() (similar to Serial::) which indicates how much data can be sent without buffering
- add probe request event handler (#2910)
- update WiFi events handling example to use new handler
Pro tip: replace blinking LED with ‘analogWrite’ and connect the pin to
a loudspeaker (or use a servo to hit a bell). Get notified when someone
with a smartphone wanders around your country house.
* Suppressed -Wunused-parameter and -Wunused-function by casting to void unused identifiers.
* Explicit initialization of all fields to suppress -Wmissing-field-initializers.
* Fixed signed/unsigned integer comparison.
* memset initialization of structs.
* More -Wunused-parameter fixes.
