93be699ab2 meson: Add more qt options and eliminate all automagic
The qt5 and qt6 plugins will now correctly error out if you enable the
option, and you can also now explicitly ensure that wayland, x11,
eglfs support is actually functional by enabling the options. It was
too easy to build non-functional support for these.

8b9f1278b2 jack: tone down log ERRORs in case no JACK server is running
jackaudiosink and jackaudiosrc have a rank and might be plugged
as part of auto-plugging inside playbin and playsink or the
autoaudiosink/autoaudiosrc elements, so we don't really want to
spew ERROR log messages in that case, which is consistent with
what alsasink and pulseaudiosink do.

This is less noticable on Linux because pulseaudiosink has a
higher and alsasink which has the same rank comes before jack
in the alphabet.

689dbd1fbe jack: Dynamically load libjack at runtime instead of linking
In order to provide build and provide the jack plugin with the prebuilt
binaries of gstreamer we distribute with releases, we can not depend
on an external dependency nor can we ship plugins linking to libraries
we don't provide.

We can also not provide jack ourselves, as it would likely cause a
mismatch with the jack daemon on the host.

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.

Fix an off-by-one in gst_hls_media_playlist_sync_to_playlist() that would ignore
the first fragment in the reference playlist.  The error was harmless, since we
expect the reference playlist to be older than the playlist we're
synchronising (so the first/oldest segment in the reference playlist will likely
not exist in the new playlist), so this is just for correctness.

Also fix a segment leak in gst_hls_media_playlist_advance_fragment() when
ignoring the partial_only segment.
