8ec6ef8ca4 adaptivedemux: Don't parse URI unnecessarily
Short-circuit parsing and recreating the playlist URI if
no HLS directives are going to be applied to it.

Fixes problems playing some streams (YouTube) that have
unneeded escaped characters in the URI and then complain
when GStreamer removes the escaping

dd3542aa4d adaptivedemux2: Don't blindly set the main manifest URI as referer
There's no guarantee it will *actually* be the URI which refered to what we are
downloading. It could be a stream URI or anything else.

Instead of putting something wrong, put no (specific) referer as a better choice

bead28ad5c hlsdemux2: Don't set a referer when updating playlists
In the same way we don't for regular playlists in the base class.

If there is a referer specified by the app/user, the downloadhelper will set it
accordingly.

38028c9873 hlsdemux2: Make start-bitrate property work without connection-speed
Makes "start-bitrate" work without setting "connection-speed" property. Having
another property set as a requirement for this one to work is unexpected.

This commit allows to request some initial bitrate for first segment, then
go into adaptive streaming for the rest of media playback.

714628f1ec hlsdemux2: Improve live playlist update intervals
The live playlists should be updated at a defined interval. The problem is that
this interval was used *after* the playlist was finally received and processed,
which resulted in a gradual shift happening in playlist updates.

Instead store and use the time at which playlists were requested to determine
when the next one should be downloaded.

5935c8049a hlsdemux2: Fix position searching
The scanning is done in a reverse order, the proper full checks to do are
therefore:
* If the position is beyond half a "segment duration", it's in the following
segment
* If the position is within the first half of a segment, it's in that one
* If the segment is the first one and the position is within half a duration
backwards, we consider the position as being within that first segment

Also handle the case where a "partial only" segment doesn't have a reliable
duration, and therefore use the playlist target duration instead.

1c6364673d hlsdemux2: Handle all cases for starting segment calculation
The implementation wouldn't work with regular HLS streams (i.e. the final
fallback).

Now that the implementation uses time to search for the starting
segment (instead of just the n-th from the end), we can specify the correct
hold_back fallback value from the RFC

3d0e8aa07e adaptivedemux2: Fix manifest access during seeking query
Avoid a deadlock if a downstream seeking query happens while the scheduler
thread is holding the manifest lock (for example during a seek back to live).

Instead, do a more elaborate fix where the external calls that need access to a
'manifest' access a copy that's updated during a manually triggered manifest
update callback.
