Move the card->ignored check to only apply to ACTION_CHANGE, not ACTION_REMOVE. This ensures that ignored cards can still be properly removed when they are unplugged.

Remove the hard skip for IPv4 link-local addresses and add an interface
binding (matching the existing IPv6 link-local behavior).
The host needs a link-local address on the interface (ip addr add
169.254.x.x/16 dev wlan0 or via NetworkManager +ipv4.addresses).
Fixes#4830
The filter graph has, after parsing, a default number of input and
output ports. This is based on the description or the first/last element
input and output ports. Pass this information in the properties when
we emit the info.
Don't use the number of configured input/output ports as the default
number of channels in filter-chain because this is only determined after
activating the graph. Instead, use the default input/output channels.
The result is that when you load filter-chain without any channel
layout, it will default to the number of input/outputs of the graph
instead of 0. This allows for the node to be visible in the pulseaudio
API.
Fixes#5084
Without this change the playback with different number of channels
fails with `input port %s[%d]:%s already used as input %d, use mixer`
on the first port.

Fixes#4866
We sync the filter graph in two places, make a function so that both
places do the same thing.
Make node_reset clear the setup flag so that we don't have to do that
twice.
If the the audioconvert.filter-chain.N property is set early, they will
be added to the active_graphs list but with setup = false. When the node
starts, setup_convert is called, but the graphs aren't added to
filter_graphs. Run the do_sync_filter_graph at the end of setup_convert
to add them.
If we have in and out rates with a very small GCD, we might end up with
a lot of phases. Limit the number of phases to 1024 and switch to
interpolating mode. 1024 phases is enough to accurately interpolate
from.
Together with the MAX_TAPS limit we will never create a filter
size that overflows 32 bits.
Fixes#5073
Our AVX optimizations are really AVX2 so rename the files and functions
and use the right HAVE_AVX2 and cpu flags to compile and select the
right functions.
Fixes#5072
Make the parametric-equalizer module destroy the underlying filter-chain
module on destruction. This makes the EQ nodes get destroyed on unload.
Fixes#5045
WirePlumber recently added a mechanism to force mono mixdown on audio
outputs, which is a useful feature for accessibility. Let's also expose
that setting via libpulse for existing audio settings UIs to be able to
use.
Force filter graph reconfiguration in setup_convert.
When adding/removing filter-graphs, only perform setup when we were
already setup, otherwise we will do this in setup_convert later.
Don't do channelmix_init when we were not setup.
Deactivate the filter-graphs when we suspend.
Fixes#4866
First do the essential properties to set up the node, then set up the
node and then parse the params. The params might do some setup that
relies on a completely configured node, such as emit events.
Use per port allocated memory so that we can easily increase the size
and add more buffers. This is necessary when we add filter-graphs that
require more ports.
Do some of the counting of the nodes and controls when we add a node
to make things easier later.
Do the setup of the graph controls after loading the graph because we
know exactly how many controls we will have.
Fixes controls being unavailable until the filter-graph is activated.
Pipewire uses a rate of 256/7680 with the integrated camera of Apple
silicon Macbooks. To calculate pw_time.delay correctly in this case it
has to be divided by time->rate.num. Without this division the delay
contribution of the `((latency->min_ns + latency->max_ns) / 2)` term
ends up as 255 which are 8.5 seconds.
pipewiresrc reports the delay as latency in the gstreamer pipeline which
results in rendering a frame every 8.5 seconds.
I suspect the non-normalized rate of 256/7680 is another bug in
pipewire. The rate for an UVC webcam is reported as 1/30. Both
Video4Linux2 devices report a discrete frame interval of 0.033s (30fps).

Use a simple free/active linked list for the filter-graphs and insert
the new filters in the right position in the list. Then simply copy the
list to an array for the processing thread.
when reconfiguring, set up all the filters again because the number of
channels might have changed.
When parsing the graph, parse the input and output port names into
a separate string array. This was we can keep them around when
setting up the graph.
Instead of setting up the graph right after loading it, do the graph
setup when we activate the graph. This makes it possible to pass the
input channels to the filter-graph and let it create the right amount of
plugins and ouput channels.
When setting up the graphs in the audioconverter, pass the current
number of channels as the input to the graph and keep track of the
channels that each filter produces.
This way we can also load a custom upmix or downmix graph, for example.
GST_SECOND * t.rate.num can turn into a negative gint, resulting in
assertions like:
_gst_util_uint64_scale_int: assertion 'num >= 0' failed
Just use the 64bit version instead.
(cherry picked from commit 77a5100280)
When we fire the timer event, mark the next timeout as NULL because
nothing else is going to timeout anymore until we rearm the timer.
This has the effect that if we cancel and add the same timer from the
callback that we will reprogram the timer with the new timeout instead
of thinking the item as already programmed.
Use the timer queue for scheduling stream and object data timeouts.
This avoids allocating timerfds for these timeouts and the timer queue
can handle many timeouts more efficiently.
If we don't get a link on a stream, we might never send a create stream
reply. The client handles this fine by timing out after 30s and dropping
the stream, but the server holds on to the pw_stream forever (or until
the client quits).
Let's add a timer to clean up such streams on the server.

The interface of string typed controls has recently been changed in
libcamera[0], which affects `properties::Model`, so adapt to that change
in such a way that is compatible with both the new and old versions.
