Related to this discussion and to bug#14774 (audit_log function, which
is only in GnuTLS 3.x)...

I found that many platforms are still on GnuTLS 2.x.  Unfortunately I
think we should keep compatibility with 2.x for a while longer and make
the 3.x features optional.  I hate that ambiguity and testing is made
harder, but OTOH we would keep supporting many users.

Here's a simple patch that finds GnuTLS 3.x and sets HAVE_GNUTLS3.  In
that case we set the audit_log function; otherwise we keep
compatibility.  Note the configure message that GnuTLS 3.x is highly
recommended.

Let me know what you think and if I should be more forceful here.  If I
should keep the compatibility path I will also add a
`gnutls-library-version' string variable so ELisp code can use it and
start moving on the tasks listed in this thread.

Thanks
Ted
