This is needed for example for Clang compiler which uses different
annotations than GCC. It will make WebRTC to happily use PipeWire
since the spa library is header-only and WebRTC defaults to use
Clang with -Wimplicit-fallthrough.
Add a asprintf helper function that handles errors correctly.
Use this in places where we use asprintf to avoid warnings when we
don't check the return value.
Make the thread_loop alloc its own loop by default to simplify
some core. Add extra new_full method to pass a custom pw_loop.
Make other loop implementations ready to support custom loops
if we want that later.
The proxy API is the one that we would like to expose for applications
and the other API is used internally when implementing modules or
factories.
The current pw_core object is really a context for all objects so
name it that way. It also makes it possible to rename pw_core_proxy
to pw_proxy later.
The pw_remote object is really a wrapper around the pw_core_proxy.
The events it emits are also available in the core proxy and are
generally awkward to use.
With some clever new pw_core_proxy_* methods and a pw_core_connect
to create the core_proxy, we can convert all code away from pw_remote.
This is a first step in this conversion, using the pw_remote behind
the scenes. It leaks into some places because it really needs to become
its own struct in a next step.
Remove some of the unused states in pw_stream. The app can know the
state by following the format and buffer events.
Make it possible to be notified of io are updates. This should make it
possible to follow the transport etc.
Make it possible to be notified of any param changes.
Rename finish_format to update_params because that is what it does.
Make this work in the same was as the filter: updating the params
removes all old params of the types and installs the new ones.
Don't get the Props and PropInfo from the node proxy, instead get them
directly from the adapter that we have locally. Update the controls
directly on the adapter instead of going to the server first.
