Replace the AsyncDone event with an explicit done callback in the node
to signal completion of an async operation.
Pass read and write fd together with the transport
Make a default logger and mapper in a .h file to be used by examples
Remove logger and mapper from libs
Make method to set the default mapper for the debug methods
Remove port properties and replace them with port params. Move the
params from the PortInfo to enum_params.
Use the Param ranges to specify possible sizes etc.
Improve event and command init so that it can be used more easily
as compound literals.
Improve volume
Make it possible to use graph scheduler in test-mixer
Use dynamic types for the data and meta types.
Move the meta into a separate header.
Remove port state, we can keep track of that ourselves.
Add size to MetaDataEnable params
Use absolute indexes that we let wrap around. We can then easily detect
how much we under of overflowed by using serial number arithmetic.
Remove the Areas, we can trivially compute this ourselves, move the
logic in read/write_data.
Remove the node state. The state of the node is based on the state
of the ports, which can be derived directly from calling the port
methods. Track this state in the Port instead.
Add a mixer module that puts a mixer in from of audio sinks. This allows
multiple clients to play on one sink (still has some bugs). do some
fixes in the mixer and the scheduler to make this work.
Unify input and output io areas.
Add support for ranges in the io area.
Automatically recycle buffers in the output areas in process_output
Improve the mixer, add use_buffer support, use a queue of input buffers,
fix mixing, add support for ranges.
Fix mixer and v4l2 tests
Make allocparams into pod objects. This makes it easy to serialize,
copy, create and intersect them.
Add convenience macros for properties
Add helper function to collect object properties.
