Only non-import path is affected by this fallback:
- drop the export info since the fd type can only be dma_buf here
- allocate gbm bo and export a fd for import as external memory
- track the gbm bo in vkr_device_memory
- vkr_context_get_blob exports fd from the bo and we destroy bo here
- vkr_device_memory_release ensures the gbm bo gets destroyed

Currently we do the below:
1. Open one render node fd per renderer process
2. Track gbm_device pointer per vkr_physical_device
The main reason is that the fallback path requiring the gbm_device
does not use drm render node for physical device.
Later we might:
1. Figure out render nodes for different physical devices
2. Open render node and create gbm_device per vkr_physical_device

4. sanity check memory export before forcing export, which requires

Add a new command associated to glLinkProgram. With this we should be
able to compile and link shaders when requested by the user.
Together with the command we expect an array of shader handles attached
to the program, where each position of the array corresponds to a pipe

The swizzling didn't take into account that the destination might
actually only read a few components or just one, so that the
applied swizzling could even become invalid because code like
dest.z = vec4(dest.z.x, dest.z.y.dest.z.z. dest.z.w)
could be created. The check for when to apply the swizzling was also
not correct because the two values compared came from different
name-spaces.
To fix this, just check whether the TEXTURE_NEEDS_SWIZZLE is set,
and when loweing in the shader, take only the components into account
that are actually written.
This also needs a fix for the alpha-format override to add the
TEXTURE_NEEDS_SWIZZLE flag.
Finally take the shader type into account when checking the number
of sampler views.

Sometimes we receive FS shaders where some output was optimized away.
In this case we have to set the output locations explicitly, but it is
no problem if we always do this. On GL this can always be done by using
glBindFragDataLocationIndexed, it is supported since at least GL 3.3,
and the alternative, setting the layouts in the shader, requires the same
OpenGL. On GLES we have to emit explict locations if EXT_blend_func_extended
is not supported. This fises rendering of "The Long Dark".
v2: - Emit EXT_blend_func_extended in FS if extension is available
since this is required when not emitting the explicit locations
(Robert Wenzel)
- call glBindFragDataLocationIndexedEXT on GLES because that's what the
extension requires
v3: use sizoef(buf) instead of hard-coding size (John)
