The only encoders avaliable using mediacodec were h264 and hevc. This
patch adds the vp9 encoder.

This patch add another ARIB caption decoder using libaribcaption
external library.
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ass as same as libaribb24.
Advantages compared with libaribb24 on ASS subtitle are:
* Subtitle positioning.
* Multi-rect subtitle: some captions are displayed at different
position at a time.
* More stability and reproducibility.
To compile with this feature:
* libaribcaption external library has to be pre-installed.
https://github.com/xqq/libaribcaption
* configure with `--enable-libaribcaption` option.
`--enable-libaribb24` and `--enable-libaribcaption` options are
not exclusive. If both enabled, libaribcaption precedes as
order listed in `libavcodec/allcodecs.c`.

This allows users to specify an argument such as './configure
--enable-lto=thin' to use ThinLTO with Clang. The old functionality with
'./configure --enable-lto' is preserved.

HLS segments may be MPEG-TS or fragmented MP4, so those (de)muxers are
required for reading/writing HLS media segments.
Fixes functionality with --disable-everything --enable-demuxer=hls
--enable-muxer=hls
This commit does for AVOutputFormat what commit
20f9727018 did for AVCodec:
It adds a new type FFOutputFormat, moves all the internals
of AVOutputFormat to it and adds a now reduced AVOutputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for muxers (it is still a mess due to lavd).

Like what we did for scale_qsv filter, we use QSVVPPContext as a base
context to manage MFX session for deinterlace_qsv filter.

Use QSVVPPContext as a base context of QSVScaleContext, hence we may
re-use functions defined for QSVVPPContext to manage MFX session for
scale_qsv filter.
In addition, system memory has been taken into account in
QSVVVPPContext, we may add support for non-QSV pixel formats in the
future.

It is a URL rewriter for IPFS gateways, not an actual implementation of
IPFS, and naming it as such was both incorrect and misleading.

Currently, several components select atsc_a53, despite
not using anything from it themselves. They only select
it because parsing SEI messages adds an indirect dependency.
But using direct dependencies is more natural, so add
dedicated subsystems for them.
It already allows to remove a superfluous dependency of
the HEVC QSV encoder on hevc_sei and atsc_a53.
Adding new subsystems only becomes effective after a reconfiguration.
In order to force this, some needed headers (which are only included
implicitly before this commit) were included explicitly in
libavformat/allformats.c.

Add qsv_transcode example which shows how to use qsv to do hardware
accelerated transcoding, also show how to dynamically set encoding
parameters.
examples:
Normal usage:
qsv_transcode input.mp4 h264_qsv output.mp4 "g 60"
Dynamic setting usage:
qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1"
100 "g 120"
This command initializes codec with gop_size 60 and change it to
120 after 100 frames

x265_sei is available since X265_BUILD 88. Bump required version
to 89 to fix the regression from commit 1f58503013, and remove a
conditional compilation.
