"Driver" isn't a great word for what this layer is, it's effectively a
build-time choice about what OS you're targeting. Despite that both of
the extant backends totally ignore the display argument, the old code
would only set up the backend relative to a display.
That causes problems! One problem is it means eglGetProcAddress can
generate X or Wayland protocol when it tries to connect to a default
display so it can call into the backend, which is, you know, completely
bonkers. Any other EGL API that doesn't reference a display, like
EGL_EXT_device_query, would have the same issue.
Fortunately this is a problem that can be solved with the delete key.

The dmabuf interface requires a valid modifier to be sent. If we don't
explicitly get a modifier from the driver, we can't know what to send;
it must be inferred from legacy side-channels (or assumed to linear, if
none exists).
If we have no modifier, then we can only have a single-plane format
anyway, so fall back to the old wl_drm buffer import path.

dri2_fallback_swap_interval() currently used to stub out swap interval
support in Android backend does nothing besides returning EGL_FALSE.
This causes at least one known application (Android Snapchat) to fail
due to an unexpected error and my loose interpretation of the EGL 1.5
specification justifies it. Relevant quote below:
The function
EGLBoolean eglSwapInterval(EGLDisplay dpy, EGLint interval);
specifies the minimum number of video frame periods per buffer swap
for the draw surface of the current context, for the current rendering
API. [...]
The parameter interval specifies the minimum number of video frames
that are displayed before a buffer swap will occur. The interval
specified by the function applies to the draw surface bound to the
context that is current on the calling thread. [...] interval is
silently clamped to minimum and maximum implementation dependent
values before being stored; these values are defined by EGLConfig
attributes EGL_MIN_SWAP_INTERVAL and EGL_MAX_SWAP_INTERVAL
respectively.
The default swap interval is 1.
Even though it does not specify the exact behavior if the platform does
not support changing the swap interval, the default assumed state is the
swap interval of 1, which I interpret as a value that eglSwapInterval()
should succeed if called with, even if there is no ability to change the
interval (but there is no change requested). Moreover, since the
behavior is defined to clamp the requested value to minimum and maximum
and at least the default value of 1 must be present in the range, the
implementation might be expected to have a valid range, which in case of
the feature being unsupported, would correspond to {1} and any request
might be expected to be clamped to this value.
Fix this by defaulting dri2_dpy's min_swap_interval, max_swap_interval
and default_swap_interval to 1 in dri2_setup_screen() and let platforms,
which support this functionality set their own values after this
function returns. Thanks to patches merged earlier, we can also remove
the dri2_fallback_swap_interval() completely, as with a singular range
it would not be called anyway.
v2: Remove dri2_fallback_swap_interval() completely thanks to higher
layer already clamping the requested interval and not calling the
driver layer if the clamped value is the same as current.

they get unexpected results/behaviour.
