* Remove stale putative MD2 support This hasn't worked in a while, presumably since one of our upstream merges. Don't bother making it work, since MD2 is generally considered insecure. * Land mbedtls 2.16.3-77-gf02988e57 * TLS: remove some dead code from espconn_mbedtls There was some... frankly kind of scary buffer and data shuffling if ESP8266_PLATFORM was defined. Since we don't, in fact, define that preprocessor symbol, just drop the code lest anyone (possibly future-me) be scared. * TLS: espconn_mbedtls: run through astyle No functional changes * TLS: espconn_mbedtls: put the file_params on the stack There's no need to malloc a structure that's used only locally. * TLS: Further minor tidying of mbedtls glue What an absolute shitshow this is. mbedtls should absolutely not be mentioned inside sys/socket.h and app/mbedtls/app/lwIPSocket.c is not so much glue as it as a complete copy of a random subset of lwIP; it should go, but we aren't there yet. Get rid of the mysterious "mbedlts_record" struct, which housed merely a length of bytes sent solely for gating the "record sent" callback. Remove spurious __attribute__((weak)) from symbols not otherwise defined and rename them to emphasize that they are not actually part of mbedtls proper. * TLS: Rampage esp mbedtls glue and delete unused code This at least makes the shitshow smaller * TLS: lwip: fix some memp definitions I presume these also need the new arguments * TLS: Remove more non-NodeMCU code from our mbedtls * TLS: drop support for 1.1 Depending on who you ask it's either EOL already or EOL soon, so we may as well get rid of it now.
