Metadata filter output is passed through an Awk script comparing floats
against reference values with specified "fuzz" tolerance to account for
architectural differences (e.g. x86-32 vs. x86-64).

This reverts commit 740e557d, reversing
changes made to 932e28b1.

The commit apparently broke builds with shared libs, and "suggesting"
the use of external libraries that need to be explicitly enable has
dubious usefulness anyway.

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.

Fixes #6649.

It's unnecessary after a call to av_packet_ref().
