The function already returns `ssize_t`, so do not use `errno`
to communicate the reason for failure, instead, return the
negative errno.
`pw_getrandom()` was inconsistent in this regard because
sometimes it simply returned a negative errno without
setting `errno`. This change fixes that as well.
Document the pulse.fix properties.
Add an option to disable handling of the FIX flags when the pulse.fix.
property is set to an invalid value/0.

dlopen lv2 and sofa plugin modules instead of hardcoding them into the+
filter-chain. This also makes it possible to add more plugin module
types externally.
If we can't find data ports to link, try to find notify/control ports
when making a link.
When applying the link, place the output of the notify as the control
data.
Don't instantiate the graph when negotiated but when starting. This
allows us to get to the target graph rate in case the format rate is
supposed to follow the graph rate.
See #2969
The old way fails, if a distro has the header but not the library,
which can happen on at least Gentoo with multilib deployments,
where the shared header is present but non-native libraries might not.
This could still fail, if a distro had some but not all libraries for
some architectures but hopefully no one did that. In that case, a compile
test would likely be required via cc.check_header() instead but let's try
the faster fix first.

Use the port_set_mix_info to add and remove mix info information to the
client.
Previously it was impossible to clean up mix_info.
With this change we can also simplify the jack peer port detection.
Because the mix info is always sent before the link appears we can
simply look up the info when the link appears.
When we don't set a rate, assume both input and output streams are
following the graph rate and so disable the resampler.
This mostly works around an issue where the input and output could
negotiate to different rates in some cases. With the resampler disabled
this would still result in the same amount of samples going in as
comming out instead of a stuttering mismatch.
See #2969
When one side of the loopback suspends, do a EnumFormat params to force
renegotiation on the other side as well.
Suppose this:
1. sink/filter/pw-play plays at 48000Hz
2. pw-play goes away, sink and filter-sink suspend, filter-playback
idles
3. pw-play starts with 44100Hz
4. sink/filter-sink renegotiate to 44100Hz, filter-playback is still
at 48000Hz and pitch shifted.
We might want to manually suspend the IDLE nodes instead but for now
this is a good workaround.
Fixes#2969
There is already an id in the port_mix structure that can be used to
index the mix structures in map if needed, the mix_id is the port_id of
the mixer and should not be confused.
Our sink and source callbacks are called twice, once when the graph
starts and once when it completes, make sure we don't signal the jack
graph twice or we get corrupted output.
Fixes#3255
Add an option to export the node from the factory.
That way you can locally create a node from a factory and then export it
to the server. This is handy to make object in the server from a config
file using the node-factory.
