Multimedia processing graphs

Move some things around. Move the duration of the current cycle to the clock. Also add the estimated next timeout to the clock. Add a generic media specific counter to the clock. Clean up the position_bar info. We can do with only a double beat value and make the signature in floats. Flesh out the io_position info. This has now the information needed to convert a raw clock time into a stream time. It basically has the same kind of features as GStreamer segments such as looping, variable rate playback etc.. It also contains the state of the timeline (paused/playing) and it can be used to update the position and state from clients. There is also extended information in the position field that clients can update when they can. Plugins basically only update the clock info they get (and use the position info to check if they are slaved or not). Before each cycle, check if there is a pending position update and apply it. |

PipeWire
--------
PipeWire is a server and user space API to deal with multimedia
pipelines. This includes:
- Making available sources of video (such as from a capture devices or
application provided streams) and multiplexing this with
clients.
- Accessing sources of video for consumption.
- Generating graphs for audio and video processing.
Nodes in the graph can be implemented as separate processes,
communicating with sockets and exchanging multimedia content using fd
passing.
Building
--------
Pipewire uses the Meson and Ninja build system to compile. If you're not
familiar with these tools, the included "autogen.sh" script will
automatically run the correct meson/ninja commands, and output a Makefile.
It follows that there are two methods to build Pipewire, however both rely
on Meson and Ninja to actually perform the compilation:
$ ./autogen.sh
$ make
or the Meson/Ninja native method:
$ meson build
$ cd build
$ ninja
You can see the available meson options in meson_options.txt file.
