provide full version descriptor, displayed in debug mode (esp8266#4467)

* provide full version descriptor, displayed in debug mode

* unix: shows core version like under windows when git is unavailable

* store strings in progmem

* version string honours NDEBUG

* add ARDUINO_ESP8266_GIT_DESC
restore ARDUINO_ESP8266_GIT_VER
restore global variable "core_version"
don't print full version on setDebugOutput(true)
set platform.txt version to 2.4.1-pre
hide irrelevant boot version
fix typo

* lwip2: fix disconnection/reconnection issue
also:
improve version string
remove useless message

* lwip2: bump tag before 2.4.1

* lwip2: improve netif flags management on git side

* full-version string: remove useless NDEBUG in separate source file

* do not automatically enable sdk messages along with core messages

* automatically reenable sdk messages along with core messages *before* setup not after

* check serial port when showing version-string + move sdk messages enabler in hardware serial

* + license header

* updated and tested windows commands in platform.txt (without git)

* updated and tested windows commands in platform.txt (without git)

* update package builder accordingly
