2022-04-27lavf/tls_mbedtls: add support for mbedtls version 3Timo Rothenpieler
- certs.h is gone. Only contains test data, and was not used at all. - config.h is renamed. Was seemingly not used, so can be removed. - MBEDTLS_ERR_SSL_NO_USABLE_CIPHERSUITE is gone, instead MBEDTLS_ERR_SSL_HANDSHAKE_FAILURE will be thrown. - mbedtls_pk_parse_keyfile now needs to be passed a properly seeded RNG. Hence, move the call to after RNG seeding. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
