* Remove warnings, errors during host tests in CI
Debug strings often included format parameters which did not exactly match
the passed in format parameters, resulting in warnings in the host test build
process like
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiAP.cpp:107:20: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]
107 | DEBUG_WIFI("[AP] SSID length %u, too long or missing!\n", ssid_len);
| ~~~~~~~~
| |
| size_t {aka long unsigned int}
````
Fix by applying casting or PRxxx macros as appropriate.
Also, fix one debug message which was trying to use a `String` as a `char *`:
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiMulti.cpp: In member function ‘wl_status_t ESP8266WiFiMulti::connectWiFiMulti(uint32_t)’:
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiMulti.cpp:331:34: warning: format ‘%s’ expects argument of type ‘char*’, but argument 3 has type ‘String’ [-Wformat=]
331 | DEBUG_WIFI_MULTI("[WIFIM] Connecting %s\n", ssid);
````
* Clean up SpeedTest.ino host build
* Put longer string literals into PROGMEM
* Use Flash Strings for Debug output
This is hopefully very infrequently used, so it shouldn't
be in main memory.
Adding getMode function to ESP8266WiFiClass.cpp

Add return typecast
When network interface is down, some nasty things happen, for instance tcp_connect returns without ever calling error callback.
This change adds some workarounds for that: before doing a tcp connect and DNS resolve we check if there is a route available.
Also added a listener for wifi events which stops (aborts) all the WiFiClients and WiFiUDPs when wifi is disconnected. This should
help libraries detect disconnect properly.
