[webvtt] Fix timestamp overflow adjustment (#698)
In some streams, empty segments may appear with a bogus, non-monotone MPEG timestamp.
This should not be considered as an overflow

[webvtt] Merge daisy-chained duplicate cues (#638)
Fixes: https://github.com/yt-dlp/yt-dlp/issues/631#issuecomment-893338552

Previous deduplication algorithm only removed duplicate cues with
identical text, styles and timestamps.  This change also merges
cues that come in ‘daisy chains’, where sequences of cues with
identical text and styles appear in which the ending timestamp of
one equals the starting timestamp of the next.

This deduplication algorithm has the somewhat unfortunate side effect
that NOTE blocks between cues, if found, will be emitted in a different
order relative to their original cues.  This may be unwanted if perfect
fidelity is desired, but then so is daisy-chain deduplication itself.
NOTE blocks ought to be ignored by WebVTT players in any case.

96fccc101f [downloader] Allow streaming unmerged formats to stdout using ffmpeg
For this to work:
1. The downloader must be ffmpeg
2. The selected formats must have the same protocol
3. The formats must be downloadable by ffmpeg to stdout

Partial solution for: https://github.com/ytdl-org/youtube-dl/issues/28146, https://github.com/ytdl-org/youtube-dl/issues/27265

Option to choose different downloader for different protocols
* Renamed `--external-downloader-args` to `--downloader-args`
* Added `native` as an option for the downloader
* Use similar syntax to `--downloader-args` etc. Eg: `--downloader dash:native --downloader aria2c`
* Deprecated `--hls-prefer-native` and `--hls-prefer-ffmpeg` since the same can now be done with `--downloader "m3u8:native"` and `m3u8:ffmpeg` respectively
* Split `frag_urls` protocol into `m3u8_frag_urls` and `dash_frag_urls`
* Standardize shortening of protocol names with `downloader.shorten_protocol_name`

More improvements to HLS/DASH external downloader code
* Fix error when there is no `protocol` in `info_dict`
* Move HLS byte range detection to `Aria2cFD` so that the download will fall back to the native downloader instead of ffmpeg
* Fix bug with getting no fragments in DASH
* Convert `check_results` in `can_download` to a generator
