[Verse-dev] More API naming

[Emil Brink]

Eskil,

I think the verse_send_connect() function should be renamed. My
suggested new name would be verse_session_create(). Motivation:

* It complements the verse_session_destroy() function nicely.
* It does more than just send the connect command, since it
  is going to wrap the entire authentication handskaking seq-
  uence.
* It makes sense to _not_ call it "send", since sending is done
  inside a session.

What do you think?
