Add helper to complete GPU operations to allow synchronization prior to
CPU accesses like mapping buffers on platforms that require it (ie ARM
Mali).

Mesa emulates planar format sampling with per-plane samplers. With this
change, the guest can pass the plane index when creating a sampler view
from a virgl resource to create a per-plane sampler view. The index can
be passed in place of the texture layer, as that will always be 0 for
planar images.

Adds a VIRGL_RENDERER_USE_GLES flag for specifying the API to request
when creating the EGL context.
Users can enable this flag when using vtest with the VTEST_USE_GLES
environment variable.

To make it easier to run the test suite on environments without graphics
hardware, add an environment variable VIRGL_EGL_SURFACELESS that will
force the use of the surfaceless platform.
Combined with the following flags, we can run virglrenderer and its
tests without any graphics hardware or windowing system present:
LIBGL_ALWAYS_SOFTWARE=true GALLIUM_DRIVER=llvmpipe VIRGL_EGL_SURFACELESS=yes

virgl_renderer_resource_get_info() doesn't return the underlying image
stride. eglExportDMABUFImageMESA() does. This fixes imports failing
due to a stride mismatch under certain resolutions. (note that qemu
uses its own export methods, perhaps because Gerd noticed the problem
with virgl egl export functions)
