fate: add tests for psnr and ssim filter
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).

aarch64: vp9itxfm: Restructure the idct32 store macros
arm: vp9itxfm: Avoid .irp when it doesn't save any lines
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.

lavf/tls_gnutls: fix warnings from version check
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.

This commit implements a psychoacoustic system for the native Opus
encoder. Its unlike any other psychoacoustic system known since its
capable of using a lookahead to make better choices on how to treat the
current frame and how many bits to allocate for it (and future frames).
Also, whilst the main bulk of the analysis function has to run in a
single thread, the per-frame anaylsis functions does not modify the main
psychoacoustic context, so in the future it will be fairly trivial to
run those as slice threads.
Some of the changes introduced:
- v4l2: code cleanup and abstractions added
- v4l2: follow the new encode/decode api.
- v4l2: fix display size for NV12 output pool.
- v4l2: handle EOS (EPIPE and draining)
- v4l2: vp8 and mpeg4 decoding and encoding.
- v4l2: hevc and vp9 support.
- v4l2: generate EOF on dequeue errors.
- v4l2: h264_mp4toannexb filtering.
- v4l2: fixed make install and fate issues.
- v4l2: codecs enabled/disabled depending on pixfmt defined
- v4l2: pass timebase/framerate to the context
- v4l2: runtime decoder reconfiguration.
- v4l2: add more frame information
- v4l2: free hardware resources on last reference being released
- v4l2: encoding: disable b-frames for upstreaming (patch required)

GnuTLS: eat PREMATURE_TERMINATION error
GnuTLS is too strict on the SSL shutdown alert, and it's neither
mandatory in the spec or critical. As it's ignored in OpenSSL, we
should also suppress it in GnuTLS as well.
