configure: Use the right pkgconf file for openjpeg

The current release of version 1 uses libopenjpeg1.

hevc: Use get_se_golomb_long

Do not use inline functions that refer to tables present in other
libraries.

golomb: Add a get_se_golomb_long

Useful in libavformat mostly.

Work around broken floating point limits on some systems.

The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
    [....]
}

mxfdec: Validate parameters to strftime

The MSVCRT version of strftime calls the invalid parameter handler
if the struct values in struct tm are invalid. In case no invalid
parameter handler is set for the process, the process is aborted.

This fixes fate failures on MSVC builds since 570af382.

matroskaenc: enable Annex B to MP4 conversion for HEVC tracks.

matroskaenc: write private data in hvcC format for HEVC.

movenc: allow muxing HEVC in MODE_MP4.

movenc: enable Annex B to MP4 conversion for HEVC tracks.

movenc: write hvcC tag for HEVC.

movenc: use 'hev1' tag for HEVC in MODE_MOV.

'hvc1' requires that parameter set NAL units be
present only in the samples entry, but not in the
samples themselves, requiring that additional
parameter sets, if present, be filtered out of the
samples and placed in new, additional sample entries
if they override or otherwise conflict with the
parameter sets present in the first sample entry.
We do not have any way of doing this at present, so
the files we produce can only comply with the
restrictions set for the 'hev1' sample entry name in
ISO/IEC 14496-15.

riff: add VP9 fourcc

riff: IPJ2 decodes with JPEG2000 decoder

Samples can be made from mencoder and jp2avi.dll codec.

movdec: handle 0x7fff langcode as macintosh per the specs

The correct point that seperates ISO and MAC language codes is 0x400
according to the current QT spec. Old QT specs did not list where this
seperation is but apparently only defined the meaning of the first 137.

libspeex: support ZygoAudio (quality 10 mode)

isom: lpcm in mov default to big endian

It is my understanding that "Unless otherwise stated, all data in a
QuickTime movie is stored in big-endian byte ordering" [1] in MOV files.

I have a couple of thousand files, which technically are invalid because
their sound sample description element 4CC is 'lpcm' but its version is
0 - and "Version 0 supports only uncompressed audio in raw ('raw ') or
twos-complement ('twos') format" [2]

Because isom.c only contains a mapping for 4CC 'lpcm' to
AV_CODEC_ID_PCM_S16LE, these files have their audio decoded as LE when
it is actually BE.

This commit adds AV_CODEC_ID_PCM_S16BE as the first match for 4CC 'lpcm'.
