80ddd5ba13 Fix software upload for DRM renderer with non-720p resolutions
The buffer allocated for the 720p test frame was left around
and we would attempt to reuse it even if the stream had frames
of a different size.

1c6ed8f390 Remove atomic test-only commit
This is currently race-prone because nothing is synchronizing
between other Qt and SDL uses of DRM master, so it can cause
false negatives if we can't retake master ourselves.

e6f41f5574 Improve DRM renderer plane compatibility testing
For atomic drivers, use a test-only commit to fully exercise the
path that we will be using when rendering.

For legacy drivers, mask the variable portion of Broadcom modifiers
before matching with IN_FORMATS.

bd32370b6d Fix libdrm return value vs errno confusion
libdrm is inconsistent between returning -1 with an errno set
and just returning -errno as the return value. Figuring out which
behavior a given libdrm function has require reading the source :/

8726c1c7d0 Bring back atomic async page flip support
Now that we're referencing the AVFrame to keep the buffers from
being reused during scanout, this should hopefully work better.

34881599f5 Reference the AVFrame while the backing DMA-BUFs are used for scanout
This prevents tearing and other artifacts caused by the decoder
writing to a DMA-BUF that is currently being displayed.

d3fb52c5a0 Check modifiers support in IN_FORMATS property
As it turns out, there *are* in fact hardware vendors dumb enough
to ship V4L2 decoders that output buffers which are unsupported by
any plane on their display hardware. By checking modifiers, we can
still fall back to GLES on GL_IS_SLOW=1 builds in this case.

2972022ced Remove async and non-blocking page flip support
It doesn't work well in practice for a few major reasons:
- It can result in the decoder writing on DMA-BUFs being used by the display
- It can generate page flip events that collide with Qt/SDL
- It can stall the decoder if the DMA-BUF has a fence on it from the display driver

3e5aa9b127 Simplify EGLImageFactory and remove caching logic for now
The platforms that would most benefit (embedded V4L2 decoders)
either don't use frame pooling or don't synchronize with
modified DMA-BUFs unless eglCreateImage() is called each time.

d501a627f0 Test all renderers before use
Every renderer except SDL had opted-in for testing due to various
quirks discovered over the years, so just do away with this option
and test all renderers.

6b11f43302 Don't set the output rect until after modesetting
It's possible that modesetting will also change the resolution
not just the refresh rate. This can happen in cases where the
CRTC is currently set to 4K 30 Hz and we choose 1080p 60 Hz as
a better mode match for displaying a 1080p 60 FPS stream.

1bb16be183 Allow DrmRenderer to act as a non-DRM hwaccel backend
This case basically works like a degenerate case of a DRM hwaccel
without DRM master where we just provide EGL export functionality
except that we don't even need a DRM FD in this case.

There are patches floating around the FFmpeg list for this:
