1733233060 gstaudiosrc/sink: Set audio ringbuffer thread priority 
On Windows, the ringbuffer thread function must have the "Pro Audio"
priority set, otherwise it sometimes doesn't get scheduled for
200-300ms, which will immediately cause an underrun unless you set
a very high latency-time and buffer-time.

This has no compile-time deps since it tries to load avrt.dll at
runtime to set the thread priority.

a9cab426d0 meson: Maintain macOS ABI through dylib versioning 
Requires Meson 0.48, but the feature will be ignored on older versions
so it's safe to add it without bumping the requirement.

320243050b audioaggregator: Fixate to some meaningful values if no sinkpad is configured yet 
The default caps fixation code would select a rate of 1 for example,
which is not really ideal.

1b6eed694c audioaggregator: Properly propagate caps negotiation failures 
Otherwise we'll end up doing a division by zero when clipping buffers,
and might even accept buffers for which we don't know the caps.

efa9bdccf9 meson: fix install dir for generated header files

to take account of the 'includedir' option instead of
just hard-coding 'include' here.

0ce20cef4f gstaudiodecoder: take into account GstAudioMeta::samples on the output buffers 
This is useful if the output buffers are planar and have extra padding
on each plane, in which case size/bpf does not represent the number of
valid samples.

2d38d2f1d3 gstaudiodecoder: do not aggregate output if buffers are planar 
Aggregation will break the layout, as it concatenates buffers,
and fixing it here would be much more inefficient than configuring
the actual decoder implementation to output larger buffers.

7d3c098a7c audiobasesink: Improve clock skew corrections. 
The external time should be moved only as much as needed
to get back to the ideal center point, so that the clock
is still allowed to drift both directions after the correction.
This reduces excessive back and forth corrections that were
caused by the assumption of a linear drift.

83939c81e7 audioaggregator: fix filtered getcaps 
In the situation described in
https://bugzilla.gnome.org/show_bug.cgi?id=795397,

downstream_caps consists of two structures, the first with
the preferred rate, if at all possible (44100), the second
containing the full range of allowed rates, as audioresample
correctly tries to negotiate passthrough caps.

As audioaggregator cannot perform rate conversion, it wants
to return a fixated rate in its getcaps implementation,
however it previously directly used the first structure in
the caps allowed downstream, without taking the filter into
consideration, to determine the rate to fixate to.

With this, we first intersect our downstream caps with the
filter, in order not to fixate to an unsupported rate.

e9be107e4a audioaggregator: fix channel-mask negotiation 
When outputting more than two channels, a channel-mask has to be
specified in the output caps.

We follow the same heuristic as other cases, when downstream
does not specify a channel-mask, we use that of the first
configured pad, and if there was none we generate a fallback
mask.
