Make SRP conformant to rfc 5054.

Changes are:

- removal of the addition state after client hello
- removal of all pre-rfc srp alert ids
- sending a fatal alert when there is no srp extension but when the
server wants SRP
- removal of unnecessary code in the client.

(Problem pointed out by Ben Murphy.)
