Support fork-free readiness notifications.
Without this, a service supervisor that does not implement socket
activation has no way of knowing whether or not pipewire is ready to
accept connections on the socket.
s6 is the most popular service manager that supports this mechanism.

At the moment, cross compilation may not work in certain cases because
checks are carried out against the build machine instead of the host machine.
Replace uses of `build_machine` with `host_machine` to fix that.
In native compilation, all three "machine objects" available in meson
are the same, so this change should have no effect in that case.

Init the compat types map a little earlier so that it is initialized
when we try to clear it on error.
Add the client listener earlier so that we can use the events to clean
up the map, source and connection.
The loop invoke method will already call the function directly when the
thread has been stopped and will also make sure that pending items are
flushed first.
See #2631
We set the node port io when we negotiate buffers on the port but never
unset it.
With this patch, the port io is cleared again when no mixers are on the
port. This can make the node a bit more efficient.
Read the .conf.d/ override files in the same order as the .conf files.
If we already have a .conf override file with the same name, it was one
with a higher priority and we ignore it.
This makes it possible to place a 10-rates.conf file in ~/.config that
will override a 10-rates.conf file in /etc and /usr/share.
Fixes#2629
Allows placing override configuration files into a different directory. This is
Useful when pipewire clients such as wireplumber want their fully commented
configuration files under /etc/wireplumber, and fully uncommented configuration
files under /usr/share/wireplumber.
The point is solving the issue of users copying files from /usr/share/pipewire,
which contain various critical settings in addition to tweaking the config,
and then encountering problems at upgrade time when new critical settings are
added.
Always use the DSP rate on DSP ports for format conversion, not the
previous used rate.
This avoids some resampler reconfiguration as it negotiates a non-passthrough
rate conversion and then switches to passthrough when the rate correction is
done to match the graph rate.
See #2614
Some Flatpak apps want to manage sound fully (change default outputs,
move streams from other applications). Real Pulseaudio always grants
full permissions, but pipewire-pulse doesn't, which breaks some
applications, e.g. Zoom.
Work around this by granting the manager permission if the application
also has devices=all access.
To do things properly, this probably should use the Portal media roles,
but this would need further work elsewhere.
When the stream has more channels than the filter inputs or outputs,
don't try to connect an invalid filter port but ignore the input and
clear the output.
pthread_getschedparam() always returns non-negative values, so checking
if its return value is less than zero always evaluates to false.
Also, pthread functions don't set errno. While logging a warning
message, use the return value of pthread_getschedparam() instead of
errno.
First go over all the input and collect pointers and the size that we
need to copy. Then go over all destinations and copy the source or
clear the buffer memory.
This fixes the problem where extra planes in the destination would get
a 0 size, which would make the converter produce 0 output. It also
ensure that the output size is consistent.
