e9f8c7d33a hlsdemux2: Improve media playlist updates
* When dealing with rendition streams, we attempt to synchronize the media
  playlist against the variant stream. This helps with speeding up the correct

82bd65e711 hlsdemux2: No longer re-add segments from before the playlist
When updating playlists, there is a possibility that the playlists don't
perfectly align, but the last entry of the previous playlist is *just* before
the first entry of the new playlist.

In those cases, we still can transfer the timing information from one playlist
to another, but we do not want to return that segment as being the matching one.

b9effe04e3 hlsdemux2: Use variant stream as support for synchronizing playlists
When matching playlists, there is a possibility that rendition streams will not
have been updated in time (for example because that stream started later, or
playback was paused). This would cause several playback failures and seeking
failures.

In order to still fall back on our feet, attempt to synchronize that rendition
playlist against the current variant playlist. This will attempt to match the
stream time using SN/DNS/PDT/...

  selected stream. Removes the requirement of this function to a specific output

The stream start and current position would be properly set when seeking or
activating a stream after playback started. But it would never be properly
initialized.

Set it to NONE initially to indicate to subclasses that no position has been
tracked yet. This will allow them to detect initial stream usage.

Futhermore, once the initial streams setup is done, make sure that it is set to
a valid initial value:
* The minimum stream time in live
* Or else the period start

cf887f1b8e matroskademux: Avoid integer-overflow resulting in heap corruption in WavPack header handling code
blocksize + WAVPACK4_HEADER_SIZE might overflow gsize, which then
results in allocating a very small buffer. Into that buffer blocksize
data is memcpy'd later which then causes out of bound writes and can
potentially lead to anything from crashes to remote code execution.

14d306da6d qtdemux: Fix integer overflows in zlib decompression code
Various variables were of smaller types than needed and there were no
checks for any overflows when doing additions on the sizes. This is all
checked now.

In addition the size of the decompressed data is limited to 200MB now as
any larger sizes are likely pathological and we can avoid out of memory
situations in many cases like this.

Also fix a bug where the available output size on the next iteration in
the zlib decompression code was provided too large and could
potentially lead to out of bound writes.

caa5972abd osxaudio: support hidden devices
macOS features hidden devices. These are devices that will
not be shown in the macOS UIs and that cannot be retrieved
without having the specific UID of the hidden device. There
are cases when you might want to have a hidden device, for example
when having a virtual speaker that forwards the data to a virtual
hidden input device from which you can then grab the audio.
The blackhole project supports these hidden devices and
this patch provides a way that if the device id is a hidden
device it will use it instead of check the hardware list of devices
to understand if the device is valid.
