Make special format types for planar and interleaved instead of
having a field.
Add enum for audio channel positions
Add some default audio channel layouts
Place the channel layout in the audio format when possible
alsa: place audio channel positions in format
Add sse optimized channel mixing for some common cases
Remove name from port info, it's not mandatory and in the properties
Add direction to port info
Do not use dynamic types anymore. The reason is that it's difficult:
- to maintain a shared type database over a network.
- the extra overhead when translating between processes and for
maintaining the translation tables.
- race conditions in translating in RT-threads, this is a problem
because we want to make event streams.
We now have simple enums with types and extension points for all
types. This is also nicer to use in general.
We don't need the mapper anymore or pass strings around as types.
There is a parallel type info system to get more info about ids and
enums and their hierarchy. It can also be used for debugging.
Make it possible to assign an arbitary node as the port mixer.
Also remove dynamically added ports.
Improve negotiation and allocation on the mixer ports
Add some more SSE optimisations
Move float mixer from the audio dsp to the port
Remove pw_node_get_free_port() and do things more explicitly.
Handle mixer ports in client-node
Implement audioconvert as a complex element of fmtconver,
channelmix and resample.
Make copying resample just to test.
Plug the converter into pw_stream.
Separate buffer sizes in the info. Make it possible to not set
data pointers for when we use memfd for the memory.
Improve format conversion.
Work on in-place conversion in test-convert2
