This is always passed as zero, so let's make the code a bit easier to
grok by removing this unused argument. We still need to pass zero to the
externally passed callback, though.

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

Allow resources created externally (eg gbm created buffers as
dma bufs) to be used. As an example, crosvm
(https://chromium.googlesource.com/chromiumos/platform/crosvm/)
will intercept resource creation to use minigbm to allocate
buffers that its compositor is able to properly handle since it
only supports compositing with buffers allocated via minigbm.
This patch allows direct rendering to those buffers without
requiring an extra copy.
v2: Handle missing extension better.
v3: Update commit message with more details on usage.

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)

Instead of polling the fences regularly, have a thread
that blocks for a single fence using a separate shared
context, then uses eventfd to wake up the main thread
when something happens.
Inside the guest, glmark2 typicially runs twice as fast with the thread
sync. Although in general, the performances seems to be about +30%. The
benefits is mostly for CPU-bounds tasks (when main the thread hits 100%)
A naive perf stat of the vtest renderer with glmark2 "build" test with a
fixed number of frames (500) results in the following stats data:
(do not value timing related informations, since the renderer is ran and
stopped manually)

This code ended up in the other file and really wasn't necessary
there.
Remove the transfer code from virglrenderer.c, move into main
renderer file, and match it with the corresponding transfer
reader.
This should at least fix the crash in compressed textures
with ARB_get_texture_sub_image
This merges the error/bounds checking on the transfer
code, but keeps the same API, it also uses a struct
to pass through the transfer info.
this also passes a return value out to make testing easier.
