This allows clients to seek between first played segment
and the last one in the live stream playlist with #EXT-X-PLAYLIST-TYPE:EVENT attribute.

avformat/hls: flush the subdemuxer when seeking

Since we are basically seeking the AVIOContext under the subdemuxer, we
need to flush the subdemuxer to avoid old packets from being read from
the packet queue after the seek.

avformat/hls: properly take stream_index into account when seeking

Properly take stream_index into account so that a keyframe will be
looked for in the specified stream_index only.

Similarly, only check timestamp validity against the specified
stream_index.

Also remove code for stream_index == -1 case which does not actually
happen as it is handled by generic code.

This is based on an initial patch by James Deng.

avformat/hls: open playlists immediately when AVDISCARD_ALL is dropped

Do not try to delay opening newly required playlists until a segment
switch. Applications expect that newly selected undiscarded streams are
available immediately, especially with alternative rendition streams
(selectable audio/subtitle tracks).

One might think that delaying variant stream switch until a segment
switch would allow a "seamless" switch without us having to download a
specific segment from two different variant playlists. However, that is
not the case, since the application would have to keep the previous
stream available (undiscarded) until the first packet of the newly
selected stream arrives, but by that time the demuxer would have already
downloaded the next segment of both variants.

avformat/hls: do not use sequence numbers for packet ordering

As per spec 3.4.3 ("A client MUST NOT assume that segments with the same
sequence number in different Media Playlists contain matching content.")
we cannot use sequence numbers for packet ordering.

This can be seen e.g. in the subtitle streams of
bipbop_16x9_variant.m3u8 that have considerably longer segments and
therefore different numbering.

Since the code now exclusively syncs using timestamps that may wrap, add
some additional checking for that.

According to the HLS spec all the timestamps should be in 33-bit MPEG
format and synced together.

v3: further wrap detection improvements

avformat/hls: do not care about stream start timestamps

While selecting a packet to return to caller in read_packet(), the code
corrects the timestamps for starting timestamps.

However, this is wrong, since for live streams the initial timestamps
might differ just because of the time delay between the retrieval of the
various Media Playlists.

Fortunately, spec 6.2.4 mandates that all variant streams must have
matching timestamps, so we do not need to correct for initial
timestamps.

Drop the correction code.

Note that ID3 timestamps were previously ignored, so this code was
previously actually needed.

avformat/hls: improve segment selection when restarting list reception

Improve selection of the segment sequence number when restarting the
reception of a playlist after it was suspended due to being unneeded
(due to discard flags).

The current code assumes that each playlist contains matching data with
the same sequence number, while spec 3.4.3 specifically says that that
is not the case. Often subtitle playlists also have longer target
durations as well, causing the selection to be completely wrong.

Instead prefer using the playlist segment duration information for
non-live playlists, and other means if that is not possible.

avformat/hls: track seeking on a per-playlist basis

Seeking needs to be tracked on a per-playlist basis, since the resyncing

timestamp instead of stopping after the first playlist has reached it.

configure: use TMPM in check_header_oc

Some compilers when given -x objective-c will tell that they dont support
that but return success. Using a .m file instead returns proper failure in
that case

This should fix a build failure on freebsd

configure: more properly disable header when check_header_oc() fails

This should make no difference currently
