27acab7532 Improve memory handling
Reserve 0,0 for stack allocated mem that we never free
Improve allocation in the link
Parse format and properties in-line, there is no need to allocate
memory.
Improve buffer cleanup in alsa
Add timestamps and offset to alsa

b75d9786d4 pinossrc: handle latency and liveness
Use NULL filter when the port format enumeration returns nothing.
Send clock update even when there is no clock.
Don't send data to a port when the node is not streaming
Add latency support to the clock update
Copy the unset_mask when copying the formats

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.

ac5d22ec79 Work on negotiation
Add helpers to convert between pinos and gstreamer formats.
Use pinos formats in the API.
Work on removing some hardcoded stuff and instead use the real format
from the pinos server.
Use memfd and sealing.

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.

1169c2419b Make buffer data point to memory blocks
Make buffer data point to a registered memory block by its mem_id.
Add some more helpers to allocate memfd backed memory.
Allocate buffers in memfd so that we easily share them between client
and server.
Update pts and seq in v4l2 now that this change will actually be visible
at the client.

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
