2c4dcbd66b fftools/ffmpeg: rename -enc_stats* to -stats_enc* 
This is consistent with -stats_mux*

As the options were added very recently, this should not break any

719a93f4e4 avutil/{color_utils, csp}: merge color_utils into csp and expose API 
libavutil/color_utils contains some avpriv_ symbols that map
enum AVTransferCharacteristic values to gamma-curve approximations and
to the actual transfer functions to invert them (i.e. -> linear).

There's two issues with this:
(1) avpriv is evil and should be avoided whenever possible
(2) libavutil/csp.h exposes a public API for handling color that
    already handles primaries and matricies

I don't see any reason this API has to be private, so this commit takes
the functionality from avutil/color_utils and merges it into avutil/csp
with an exposed av_ API rather than the previous avpriv_ API.

Every reference to the previous API has been updated to point to the
new one. color_utils.h has been deleted as well. This should not break
any applications as it only contained avpriv_ symbols in the first
place, so nothing in that header could be referenced by other
applications.

42a0dd6e7e fftools/ffmpeg: add an option for writing pre-muxing stats 
Analogous to -enc_stats*, but happens right before muxing. Useful
because bitstream filters and the sync queue can modify packets after
encoding and before muxing. Also has access to the muxing timebase.

d09254a658 avformat/hls: Add option to retry failed segments for hls 
Current HLS implementation simply skip a failed segment to catch up
the stream, but this is not optimal for some use cases like livestream
recording.
Add an option to retry a failed segment to ensure the output file is
a complete stream.

9a820ec8b1 ffmpeg: add video heartbeat capability to fix_sub_duration 
Splits the currently handled subtitle at random access point
packets that can be configured to follow a specific output stream.
Currently only subtitle streams which are directly mapped into the
same output in which the heartbeat stream resides are affected.

This way the subtitle - which is known to be shown at this time
can be split and passed to muxer before its full duration is
yet known. This is also a drawback, as this essentially outputs
multiple subtitles from a single input subtitle that continues
over multiple random access points. Thus this feature should not
be utilized in cases where subtitle output latency does not matter.

aecfec6f80 avfilter: add VA-API variants of the stack filters 
Include hstack_vaapi, vstack_vaapi and xstack_vaapi. They may accept
input streams with different sizes.  libva2 (VA-API 1.0+) is required.

Example:
$ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i input.h265 -filter_complex
"[0:v][0:v]hstack_vaapi" -c:v h264_vaapi out.h264

$ ffmpeg \
-hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \
-hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \
-hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \
-hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \
-filter_complex "[0:v][1:v][2:v][3:v]xstack_vaapi=inputs=4:fill=0x000000:layout=0_0_1920x1080|w0_0_1920x1080|0_h0_1920x1080|w0_h0_1920x1080" \

reordered_opaque.

Add support for it in the two encoders that offer
AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE: libx264 and libx265. Other
encoders will be supported in future commits.
