George Kiagiadakis 30576fcff8 audioconvert/fmtconvert: assume F32 on the other port when listing formats
This allows picking F32LE as the default format on links that have
no restriction and it avoids failing negotiation when the restricted
end cannot handle S16/F32/F32P

For instance this pipeline would previously fail:

  audio-dsp mode=merge ! audio-dsp mode=convert ! alsa-sink
old negotiation:     S16LE                   S24_32LE
new negotiation:     F32LE                   S24_32LE

The link between the audio-dsp nodes has no restriction, so previously
it would negotiate S16LE, which would then fail to negotiate with alsa-sink
because fmtconvert does not know how to convert S16LE to S24_32LE directly.

With this change, the middle link negotiates to F32LE, which can be
converted to anything.

PipeWire
--------

PipeWire is a server and user space API to deal with multimedia
pipelines. This includes:

  - Making available sources of video (such as from a capture devices or
       application provided streams) and multiplexing this with
       clients.
  - Accessing sources of video for consumption.
  - Generating graphs for audio and video processing.

Nodes in the graph can be implemented as separate processes,
communicating with sockets and exchanging multimedia content using fd
passing.

Building
--------

Pipewire uses the Meson and Ninja build system to compile. If you're not
familiar with these tools, the included "autogen.sh" script will
automatically run the correct meson/ninja commands, and output a Makefile.
It follows that there are two methods to build Pipewire, however both rely
on Meson and Ninja to actually perform the compilation:

$ ./autogen.sh
$ make

or the Meson/Ninja native method:

$ meson build
$ cd build
$ ninja

You can see the available meson options in meson_options.txt file.
