This should allow the compositor to start working without needing to wait for a nudge/process roundtrip. The PipeWire thread should also now only get woken up when there is actual work to be done.
Also adds a similar mapping function for the colorspace
The corrupted flag doesn't even seem to trigger a renegotiation.
`SPA_PARAM_BUFFERS_size` and `SPA_PARAM_BUFFERS_stride` are params we shouldn't even be setting, mostly because we allocate our own memory for our buffers. PipeWire also recommends not setting them for DMA-BUF types.

I pushed a few new things I found while working on multi-planar+modifiers support. I am not done working on part 2, but this PR will definitely become a prerequisite for it. |

Just some changes I thought would make the pipewire support a little bit more usable. Some of it is simply cosmetic, but the buffer sharing rework is one change I should probably explain:
pw_stream_dequeue_bufferis not thread safe, and it was being called fromrequest_buffer()directly fromdequeue_pipewire_buffer()which is not on the pipewire thread. In addition, theout_bufferatomic was not really useful, as it was exchanged once inrequest_buffer()only to be immediately exchanged back again indequeue_pipewire_buffer()(all on the same thread!)With the new changes, only when
processis called (on the pipewire thread, constantly triggered by the nudges from the compositor) should the buffers be exchanged (more) correctly.
