Bug description:  Determine if session data is available before running session_start()

Description:
------------
Sometimes it is good to be able to determine if there is session data
available before running session_start(), but if there isn't, you don't
want to start a session. A session takes resources and giving a cookie to
a user is in some cases something you only want to do if really necessary.
Here in Sweden we aren't allowed to use cookies without giving the user
knowledge in what we are storing in it.

so a session_is_available() or similar would be a good thing IMHO.
