dc01b294a2 resample: return the number of consumed samples 
We need to return the number of consumed samples, even when we don't
start from the first sample in the buffer.
Add some more logging.

d8e399dee9 audioconvert: pass state to functions 
Pass some state to convert and channelmix functions. This makes it
possible to select per channel optimized convert functions but
also makes it possible to implement noise shaping later.
Pass the channelmix matrix and volume in the state.
Handle specialized 2 channel s16 -> f32 conversion

9c8913437b audioconvert: add simple and faster resampler 
Add a sinc based resampler that, unlike speex, avoids memcpy and
works directly on the source data. It also allows for ssse3
optimizations and aligned loads. It will later switch to table
interpolation when doing variable rate.

f29d14fcc8 resample: Let the resampler object handle all channels 
Move the code to loop over all channels in the resampler itself.
This is better because the resampler can reuse its state for
each channel.

036ca89c0e audioconvert: mark ports and buffers as DYNAMIC 
Only passthrough buffer data when the buffer and ports are
marked as DYNAMIC.
Use extra buffer for nodes that keep a ref on buffers (resample).

df5c81e3be buffer: add DYNAMIC data flag

0505f2dc98 audioconvert: implement passthrough 
Add some const and SPA_RESTRICT to methods
When the input and output is the same, work in passthrough mode
where we simply copy place the input pointer onto the output buffer
without doing a memcpy.
Do memcpy when the resampler is not active.

70e62aacd7 protocol-native: pass a message around 
Pass a message around to make things more extensible later.
Keep fds per message if we ever want to write individual
messages.
Pass number of fds in the message header. We might need this to
close the fds when the proxy is gone.

a3e4726ea6 connection: add test and fix a bug 
Add a unit test for the connection

When we consumed all packets in a buffer, try to get more data instead
of failing right away.

ae7e60d790 interfaces: add subscribe params method 
Add a node subscribe params method that automatically emits the new
params when they change so that we can avoid an enum_params.
Use this in the stream object.

Remove the control messages to update controls in stream, use the
set_param. This is more overhead but allows for notifications to other
clients.

Make it possible to update many controls in one go.

9245c81227 client-node: add get_node method 
Make a get node method that binds to the server side node of the
client-node immediately. use this in the remote_export and always
return a node proxy.

Use the node proxy to get property updates and signal those in the
stream.
