While in the area, this change also renames |servername_done| to
something more reasonable and removes a documented value that was never
used. Additionally, the SNI ack was only sent when not resuming so
calculating whether it should be sent when processing ClientHello
extensions (which is after s->hit has been set) is superfluous.
Lastly, since SNI is only acked by servers, there's no need to worry
about the SNI callback returning NOACK in the client case.

This replaces the special-case in ssl3_get_message for Channel ID. Also add

handshake header size into account.
One subtlety with this flag is that a message intended to be processed with
SSL_GET_MESSAGE_DONT_HASH_MESSAGE cannot follow an optional message
(reprocessed with reuse_message, etc.). There is an assertion to that effect.
If need be, we can loosen it to requiring that the preceeding optional message
also pass SSL_GET_MESSAGE_DONT_HASH_MESSAGE and then maintain some state to
perform the more accurate assertion, but this is sufficient for now.
