Don't try to multiple the max_buffer_size with the frame scale or else
we might try to set a min_buffer_size larger than the max_buffer_size.
Instead, use the frame_scale only to scale the quantum_limit and then
clamp against the max_buffer size.
See #3000
We place the currently configured runtime settings in the properties but
clear the values when not negotiated. Don't do that but place the
defaults (when set) instead.
When we don't have the thread id yet, don't add the pollfds yet
but wait until we do our first wait operation.
Use flags for eventfd. We can use this to communicate between all kinds
of threads with read/write.
Use evl_init() in the init function, don't attach the main loop, just
the thread that dos the first poll.
Some devices appear to set Supported_Max_Codec_Frames_Per_SDU == 1 while
claiming they support two channels per stream, which is then not
possible.
In this case, limit the number of channels by the number of frames per
SDU when selecting.
Also adjust PAC sorting.
It doesn't make sense to hang these on the data loop, so let's have
these on the main loop instead. Also avoids a potential crash while
removing them (since removal happens on the main loop and the data loop
might be polling while we're doing the remove).
Don't use the current time as the nsec field in the graph clock because
it can jitter a lot. Instead, use the smoothed next_time, like we do
for timer based scheduling.
Since we track the current time against the rate converted ideal time,
lock on to the first timestamp when we reset the dll.
See #3657
Don't return the value of the last snd_pcm_resume() call because that
might be -ENOSYS when resume is not implemented for the card and then
the non-error (because we used drop/prepare later) propagates and
logs an error.
Backport from Pulseaudio. Reimplement get_data_path. We'll look for the
override files similarly as we do for other config files
(XDG_CONFIG_HOME then /etc then install location), instead of looking at
the Pulseaudio locations ~/.local/share/pulseaudio etc.

alsa-mixer: Respect XDG base directory spec when loading profile sets
Try $XDG_DATA_HOME, then $XDG_DATA_DIRS, and finally fall back to old behaviour.

These are invalid per the spec.
This adds an api.alsa.bind-ctls property to alsa-pcm sink and source
nodes, to bind a property to an ALSA PCM ctl. The property is an array
of ctl names that should be bound.
This can be handy, for example, to bind the Playback/Capture Rate
controls on a USB gadget, in order to track the PCM's state via a node
param.
This is currently wired to be read-only, but it should be easy enough to
make it writable.
Because we now always _drop/_prepare_/_start, the snd_pcm_recover()
before that is no longer useful.
Retry snd_pcm_resume() after suspend when -EAGAIN and fall back to
_drop/_prepare/_start when that fails.
We need to disable the resampler when there is a pitch element. This was
correctly done in setup_matching but not in check_position_config().

GCC 14 introduces a new -Walloc-size included in -Wextra which gives:
```
./pipewire-0.3.84/spa/plugins/bluez5/codec-loader.c:176:14: warning: allocation of insufficient size ‘1’ for type ‘struct impl’ with size ‘1032’ [-Walloc-size]
```
The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```
So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(struct impl)`. GCC then sees we're not
doing anything wrong.

When the device has not configured a format, remove the properties that
depend on the format so that they don't limit what we can configure the
device with next.
See #3613
In pw_context_recalc_graph, PipeWire takes the currently configured
clock target duration from the position as target rate. The position is
not set for the videotestsrc since the set_io function is not
implemented. This leads to a segfault when the videotestsrc is
configured and loaded.
Add the same dummy implementation of set_io as in the v4l2-source and
the libcamera-source to prevent the segfault.
BlueZ now requires endpoints to set Locations/Context, so set them to
some sensible default values. These could in principle be made
configurable later.
We calculate the available frames in read_sync but add another
check in read_frames so that we don't attempt to read more frames
than we have available to avoid xruns.
Make a function to recalculate the headroom and call it whenever the
resample state of the node can change.
When we are IRQ based scheduling but need to resample, we are actually
not driving the graph whit IRQ and need to adjust our period size and
headroom as if we are using timers.
Don't blindly clear the format when EnumFormat changes. This will
just stop the node without renegotiating.
We should probably find a new best format, check if it changed and
then Stop/configure/Resume the follower with the new format.
This fixes a stall when a node is running and you change the allowed
codecs.
vulkan_headers was a workaround for distributions providing pkg-config information
without the headers. Replacing it with a more conventional have_vulkan
and assert header availability if the option vulkan is enabled.
