* WIP compile examples on host with 'make examples' * WIP bufferize tcp input * WIP Makefile * WIP network to rework, tcp/udp to factorize, udp addresses broken * minor changes to the core * WIP basic udp working * WIP mdns * WIP mcast receiving, not sending * WIP mdns OK * beta version * SSL + doc * update travis host test command * licenses * typo * doc: arduino builder is not around: declare functions before calling them * fix with latest SSL PR, compile in 32 bits mode * fix make clean * make -m32 optional * 32bits compiler ability tester * WIP * WIP (fix 1 vtable error, still another one to hunt with using spiffs) * example astyle * fix os_printf_plus * load / save mock spiffs * fix style * fix using spiffs/mock * don't mess ram * update doc * remove leftover * optimization -Os except for CI, rename ARCH32 to FORCE32 * revert useless cast (not even compiled) * remove unused function * use proper type for pointer arithmetics * makefile: sketch object and cpp file moved to bin/ directories easier to clean, and IDE don't like them * changes for review * make use of %zd * less verbose makefile by default (option) * update readme
