b67c216a04 Make new USE_BUFFERS command
Make a new USE_BUFFERS command to atomically send a buffer array to the
remote client. We can use this to then clean up an old array and go to
the PAUSED state if possible.
Work on formats. Make one structure that can hold all video formats.
Work on pipeline suspend and resume.
Add jpeg support to v4l2.
Work on enum_formats with a filter in v4l2.

fbd6304663 Cleanups
Remove old code
Only depend on GStreamer for the plugins
Rename STOP to PAUSE because that's what it really does
Start working on format_fixate.
Remove default property value from props
Fix framerate

ca7d08c406 Work on sink
Remove _remove from properties, we can do the same with set of a NULL
value.
Add signals to the stream API to manage the buffers. Wrap those buffers
in a GstBuffer in the pinossrc and pinossink elements and pool them in a
bufferpool.
Remove SPA_EVENT_TYPE_PULL_INPUT, we can do the same with NEED_INPUT and
by using a ringbuffer.
Do more complete allocation of buffers in the link. Use the buffer
allocator if none of the nodes can allocate.
Follow the node state to trigger negotiation and allocation.
Remove offset and size when refering to buffers, we want to always deal
with the complete buffer and use a ringbuffer for ranges or change the
offset/size in the buffer data when needed.
Serialize port_info structures as part of the port_update
Print both the enum number and the name when debuging properties or
formats.

0d2f5a1386 work on port-update control message
Serialize format and properties.
Simplify the properties by moving the unset-mask inside the property
structure. We can then also just use the index of the property as the
bit in the mask.
Work on stopping on disconnect

dd1fbef28f work on memory references
Add a memory reference helper struct that we can use to track the memory
in buffers and formats.
Remove custom property get and set, the default ones will work fine.
Custom ones are problematic when we want to serialize properties in
formats etc.
Deserialized Formats are now tracked in the memory pool and can be freed
if needed.

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.

4cb90f3b86 Rework transport protocol
Remove the old PinosBuffer object and replace it with SpaControl, this
communication protocol is designed to make it possible to implement
remote nodes and so it is moved to Spa.
Move SpaBuffer into to API
Work on easier API to make formats, implement enumeration and support
for all formats in v4l2.
Improve format output in -inspect

b9320c67c2 inspect: improve output
Keep state variable to enumerate things. This allows us to remove the
expectation that the same index will give the same item.
Use a new rectangle type for video size. When enumerating sizes, this
allows us to specify relations between width and height more easily.
Remove the struct and bytes type, they are like pointer.
Add filter to enum_formats to speed up enumerations.

61caf0e19c buffer: add ptr_type to the data
We can give more info about the memory or fd that way and we can also
pass other structures as data later if we need to.

4c7cee6b28 improve buffer import
Add generic pointer metadata type that is copied on import

Make sure we use the same data and metadata as the imported buffer.
