I think the build error linked to suggests that we may not actually
support 2.12 now ('GNUTLS_E_TIMEDOUT' undeclared).

Debian and Ubuntu packages have been building with 3.2 and newer since
2014. GnuTLS 2.12 no longer exists in current releases, so I have no
objection to killing it.

It would be nice to document exactly what the actual minimum version
requirement is now. The oldest version I have readily available is
3.2.11, and it works.
