update to lwIP-2.1.0: partial SACK support by default (de-selectable in menu) (#5126)

Browse Source 
* update to lwIP-2.1.0rc1: partial SACK support
fix #4176

* hash fix

* get some flash back due to mistake in conf (fragmentation & reassembly was incorrectly enabled)
(ahah I scared you)

* add missing include files

* update to lwip-2.1.0(release) + remove unused lwIP's include files

* lwIP release 2.1.0, SACK is now default, bigger, no-SACK is selectable

* fix ldscript

* pio

* rename 'sack' option to 'feat'ure option, + IP fragmentation/reassembly

* merge, fix pio

* change internal/hidden string

* pio: more lwip2 configuration: + without sack for no change in flash footprint
