Pauli Virtanen 8159797f89 doc: reorganize Doxygen groups/modules to make more sense
The Doxygen "Modules" page is not very illuminative, as different parts
of the API are mixed together and not all parts are included.

Try to address this:

Put all parts of the public API to some Doxygen group, usually one group
per header file. Use short, systematic names.

Make these groups sub-groups of a few top-level groups, roughly
corresponding to the different logical parts of the API (core, impl,
stream, filter, spa, utilities).

/** \page page_api PipeWire API
The PipeWire API consists of several parts:
- The \ref pw_stream for a convenient way to send and receive data streams from/to PipeWire.
- The \ref pw_filter for a convenient way to implement processing filters.
- The \ref api_pw_core to access a PipeWire instance. This API is used
by all clients that need to communicate with the \ref page_daemon and provides
the necessary structs to interface with the daemon.
- The \ref api_pw_impl is primarily used by the \ref page_daemon itself but also by the
\ref page_session_manager and modules/extensions that need to build objects in
the graph.
- The \ref api_pw_util containing various utility functions and structures.
- The \ref api_pw_ext for interfacing with certain extension modules.
The APIs work through proxy objects, so that calling a method on an object
invokes that same method on the remote side. Marshalling and de-marshalling is
handled transparently by the \ref page_module_protocol_native.
The below graph illustrates this approach:
\dot
digraph API {
compound=true;
node [shape="box"];
rankdir="RL";
subgraph cluster_daemon {
rankdir="TB";
label="PipeWire daemon";
style="dashed";
impl_core [label="Core Impl. Object"];
impl_device [label="Device Impl. Object"];
impl_node [label="Node Impl. Object"];
}
subgraph cluster_client {
rankdir="TB";
label="PipeWire client";
style="dashed";
obj_core [label="Core Object"];
obj_device [label="Device Object"];
obj_node [label="Node Object"];
}
obj_core -> impl_core;
obj_device -> impl_device;
obj_node -> impl_node;
}
\enddot
It is common for clients to use both the \ref api_pw_core and the \ref api_pw_impl
and both APIs are provided by the same library.
\addtogroup api_pw_core Core API
The Core API to access a PipeWire instance. This API is used by all
clients to communicate with the \ref page_daemon.
If you are familiar with Wayland implementation, the Core API is
roughly equivalent to libwayland-client.
See: \ref page_api
\addtogroup api_pw_impl Implementation API
The implementation API provides the tools to build new objects and
modules.
If you are familiar with Wayland implementation, the Implementation API is
roughly equivalent to libwayland-server.
See: \ref page_api
