A different solution will be committed instead.

The GnuTLS version is checked through the macro GNUTLS_VERSION_NUMBER,
but this wasn't introduced before 2.7.2. Building with older versions
of GnuTLS (using icc) warns:

src/libavformat/tls_gnutls.c(38): warning #193: zero used for undefined preprocessing identifier "GNUTLS_VERSION_NUMBER"
  #if HAVE_THREADS && GNUTLS_VERSION_NUMBER <= 0x020b00

This adds a fallback to the older, deprecated LIBGNUTLS_VERSION_NUMBER
macro.

Commit 598e4168 added use of
GNUTLS_E_PREMATURE_TERMINATION, which wasn't introduced to GnuTLS
before 2.99.x / 3.x. This fixes compilation with older versions.
