1eeb59a209 avfilter/vf_drawtext: improve glyph shaping and positioning 
- text is now shaped using libharfbuz

Adds libharfbuzz dependency.

73a2252f1d avfilter/vf_bwdif_cuda: CUDA accelerated bwdif deinterlacer 
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.

pkt_timebase, which is the timebase of demuxed packets.

Drop a tautological av_packet_rescale_ts() call, as the stream and
decoder timebases are the same.

Move bessel_i0() from swresample/resample to avutil/mathematics

643cf2ec46 lavfi/vf_libplacebo: update for new tone mapping API 
This algorithm has once again been refactored, this time leading to a
dropping of the old `tone_mapping_mode` field, to be replaced by a
single tunable hybrid mode with configurable strength.

We can approximately map the old modes onto the new API for backwards
compatibility. Replace deprecated enums by their integer equivalents to
safely preserve this API until the next bump.

d637f20f05 lavfi/vf_libplacebo: switch to new gamut mapping API 
Upstream deprecated the old ad-hoc, enum/intent-based gamut mapping API
and added a new API based on colorimetrically accurate gamut mapping
functions.

The relevant change for us is the addition of several new modes, as well
as deprecation of the old options. Update the documentation accordingly.
