vtls: move md5sum into the Curl_ssl struct
The MD5 summing is also an SSL backend-specific function. So let's include it, offering the previous fall-back code as a separate function now: Curl_none_md5sum(). To allow for that, the signature had to be changed so that an error could be returned from the implementation (Curl_none_md5sum() can run out of memory). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
