Now that both the expected input and output of the resampler is placed
in the rate_match, rename the 'requested' field in pw_time to 'size'
and update the docs.
See #3750
Now that the resampler input size is set in the io_rate field when we
start we can add it to the pw_time struct as well.
This way we can know the required resampler input without having
to dequeue a buffer. This can be handy when the stream is a driver
and needs to know how much data to accumulate before starting the graph.
See #3750
Don't just forward the tag and latency events to the follower but let
the audioconvert aggregate and emit the updated tag/latency event
that is then configured on the follower.
When using the DSP mode of the audioconvert, this results in an
accumulated latency/tag from all the DSP ports instead of just
the last DSP port param update.
Put properties with media. prefix in tags in pw-cat.
The data stride for encoded formats should be 1 and also placed in the
stride in the buffer (not 0). So there is really no difference with the
regular codepath.
FFmpeg integration in pw-cat does not strictly require Compress-Offload;
for example, there could be other nodes in the graph that can handle
compressed audio.

When the stream requests a 0 size buffer, don't start the drain but
simply queue a 0 size buffer.
Sometimes, switching quantums and drivers might request a 0 buffer
async and this should not cause a drain operation.
Deprecate pw_stream_get_time() in favour of _get_time_n() that contains
the size of the pw_time structure. Make the old one fill in the fields
up to the buffered field. Make the new one use the size to decide how
much info to fill in.
Add a new buffered field in pw_time that contains the buffered data
inside the converter/resampler. This leaves the queued field with
purely the user provided size in the buffers.
Use get_time_n() in places.
Library code generally shouldn't modify global state, so pw_init()
should not result to changing the C locale.
Instead, set the C locale in main() for tools and daemons.
We'll still setlocale for LC_MESSAGES, to get translated UI elements in
wireplumber. This workaround should be removed eventually...
Make all tools output to stdout (pw-mon mostly) so that we can pipe the
output around.
Send errors to stderr.
fprintf(stdout, ...) -> printf(...)
setlinebuf for stdout so that pipe works better.
