8a6ce3b179 Make AllocParams into POD objects
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.

c951264fff spa: make events and commands as objects
So we can serialize and introspect them more easily

7fc73953cd Add POD helper objects
POD (plain old data) objects are similar to LV2 Atoms and allows storage
and construction of datastructures in memory or on the stack. They can
be copied with a simple memcpy.

The idea is to use this to construct the network messages and to replace
the structures used for describing formats and properties.

ee0aa6a2ac Implement access control
Move send and dispatch functions to the implementation. This makes it
possible to place an access check before sending and dispatching.
Add module-access that allows to bind and notify on globals owned by
the client.

3f4ccaaea2 More hacking
Add connection message for PORT_COMMAND
Add rtkit support to ask for realtime priority
work on stream states and improve negotiation
Rework of port linking works, keep separate state for realtime threads
and use message passing to update the state.
Don't try to link nodes that are removed.
Open the device in the ALSA monitor to detect source or sink
Implement send_command as async methods on the plugins, use async
replies to sync start and stop.
Work on alsa sink.
Implement async PAUSE/START on v4l2 src. move the STREAMON/OFF calls to
the mainloop because they have high latency, add the poll descriptors
from the data loop.

82414810e8 avoid deref
We can avoid a deref when we use container_of to get from the interface
to the handle.

b8f693ceea More work on memory
Add explicit DMABUF memory because we can't use it like an fd in v4l2.
mmap random fd memory and use userptr in v4l2 to use it.
Allocate buffer data memory in memfd when no node can allocate.
Improve debug some more

d828073bb8 Add port direction again
simplify port numbering again by using 0->max_ports for bot input ports
and output ports. This means we need to tall what direction the port is.
Add port_info serialize functions
Copy metadata and data when we are not sharing buffers.
Make pinossink work again.

c6861845a7 pass the client object around
Pass the client object around, it's easier to deal with than the sender
id.
Fix the ASYNC return check
Don't overwrite the fds of a pollitem, instead keep an index of their
position in the global fd array.

68148188fa Add support for async results
Add an async result code and an event to signal the completion.
Use async return values to signal completion of a method and potential
state change.
Add selected format to port update message.
Make it possible to parse into a custom copy of the command memory.
Remove state change events from the elements, we now just update the
state.
Implement async results in the proxy element
Add support for removing buffers in the client.
Fix up pinossink
Deal with async return in the links.

98993c680b Make buffer structure sharable
Use stucture offsets instead of pointers so that we can share the buffer
structure between client and server.
We can then pass an fd wrapping the memory of the buffer to the client.
Add beginnings of a memory pool

3ace7e9648 More work on implementing remote protocol
Rework things so that we negotiate buffer pools beforehand and only pass
buffer ids around We can then remove the refcount of buffers, events and
commands.
More work on buffer reuse
Use the node state changes to trigger the next step in the configuration
sequence.
Move most of the client-node to a plugin
Do buffer allocation in the port link.

05829f33e6 Work on memory allocation
We now only allow per port preallocated buffers. We exchange the index
into the array instead of passing the buffers around. We still use the
refcount to track when a buffer can be reused.
Improve API a little, allow passing the node as the first argument of
the interface call.
Implement alloc_buffer in v4l2 and improve the test.
