[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

Fix `--force-overwrites` when using `-k`
For formats that need merge, the `.fxxx` files are not removed before
downloading the corresponding `.part` files. This causes the rename to fail

Revert erroneous use of the `Content-Length` header (#637)
This reverts commit 6c907eb33f

The use of the Content-Length value here is erroneous and may lead
to truncated downloads if a compression scheme is specified in the
Content-Encoding header, as the Content-Length header refers to the
size of encoded data, not of the raw bytestream. This has been noticed
in the wild with WebVTT subtitle segments.

[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.

[nbcolympics:stream] Fix extractor
PR: https://github.com/ytdl-org/youtube-dl/pull/29688
Closes: #617, https://github.com/ytdl-org/youtube-dl/issues/29665

* Livestreams are untested
* If using ffmpeg as downloader, v4.3+ is needed since `-http_seekable` option is necessary
* Instead of making a seperate key for each arg that needs to be passed to ffmpeg, I made `_ffmpeg_args`
* This deprecates `_seekable`, but the option is kept for compatibility

pukkandan 96fccc101f [downloader] Allow streaming unmerged formats to stdout using ffmpeg
For this to work:

_parse_ism_formats was extended into _parse_ism_formats_and_subtitles;
all direct users were updated, though _extract_ism_formats was left
as a compatibility wrapper.

The SSTR downloader was also modified in order to prepare for muxing
subtitle streams, although no support for any subtitle codecs was
added in this commit.
