5fd4cffe32 lavc: add a librsvg rasterization library wrapper
Enables rendering of SVG images. This is possible since SVG images
still contain and specify the dimensions in pixels to which they've
been drawn to and thus enable browsers to display them without any
external data. Users can still override and generate images with
arbitrary resolutions.

f68ea92833 img2dec: add support for piped SVG demuxing
Only checks the extension and MIME type, since determining whether
a file is SVG is difficult since they're just XML files.

9c4e69b8ea avcodec/dcaenc: Do not abort process in case of bitrate deficit
Old behaviour - abort if at least one subband has 1bit quantizer
and consumed_bits still greater than frame_bits size. It was
a bit strange - we still could reduce bits consumption by reducing
SNR for other subbands. Same strange logic with upper threshold -
stop bits allocation if at least one subband reach 26bits.

New behaviour - if consumed_bits greater than frame_bits and all
subbands has 1 bit quantizer we restart bits allocation and allow
zero subbands.

64ad44a381 movenc/isom: update vpcC box to version 1.0 of the specification
This brings our generation of the vpcC box up to date to version 1.0
of the VP Codec ISO Media File Format Binding.

Specifically, color/transfer properties are now written with values
based on ISO/IEC 23001-8, which is the same reference specification the
AVColor* enumerations are based on.

532b23f079 videotoolbox: add hwcontext support
This adds tons of code for no other benefit than making VideoToolbox
support conform with the new hwaccel API (using hw_device_ctx and
hw_frames_ctx).

Since VideoToolbox decoding does not actually require the user to
allocate frames, the new code does mostly nothing.

One benefit is that ffmpeg_videotoolbox.c can be dropped once generic
hwaccel support for ffmpeg.c is merged from Libav.

Does not consider VDA or VideoToolbox encoding.

Fun fact: the frame transfer functions are copied from vaapi, as the
mapping makes copying generic boilerplate. Mapping itself is not
exported by the VT code, because I don't know how to test.
