Provide GnuTLS API with `gnutls-negotiate' and `open-gnutls-stream'.

  
* net/gnutls.el: Improve docs.        Remove starttls and ssl emulation.
Provide only `open-gnutls-stream' (formerly `open-ssl-stream') and
`gnutls-negotiate' (formerly `starttls-negotiate').  Remove
trivial wrapper `starttls-open-stream'.
