Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
C++20 introduced designated initializers similar to the ones found
in C99, however, in C++ designated initializers cannot be mixed
with non-designated initializers. GCC rejects mixed initializers
with an error.
Version 1 does not seem to be packaged in many distros and so they would
need to revert the patch or disable AEC. Enabling both allows for things
to move forwards gracefully.
The WebRTC echo canceler can support different rates and channels for
the record, out and playback streams.
Add a new method to pass this config to the echo-canceler.
Older gcc versions seem to require the members to appear in the
designated initializer in the order they are in the definition of
the struct when compiling C++.
otherwise compilation fails with:
../spa/plugins/aec/aec-webrtc.cpp:167:1: sorry, unimplemented:
non-trivial designated initializers not supported
};

Place the methods on the interface so that we can call them.
Rename create to init because that is what it does.
Add support for listener and events so that we can signal property
changes later.
Move all backends to dynamic libaries loaded with spa_plugin_loader so
new backends not needs changes in pipewire or pipewire dependency to
external code
