For compute shaders we put the req local memory into the streamout
places in the protocol, and we create compute shaders in a separate
lookup function
Reviewed-by: Gurchetan Singh <gurchetansingh@chromium.org>
This mostly consists of adding local memory support, and
support for the compute system values.
The req_local_mem need to be gotten from the guest side
and passed into the shader compile so we can size the
shared memory correctly.

Adds a VIRGL_RENDERER_USE_GLES flag for specifying the API to request

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

If the client sends vrend_transfer_send_readpixels a stride (and vtest does),
then it is in bytes, but glPixelStorei(GL_PACK_ROW_LENGTH, stride) expects

When guest mesa does a glReadPixel call, it expects the data to be placed
with correct row strides into the readback buffer. While for calls that
invert or require more then one IOV this is done in write_transfer_data,
for a read that only uses a small area and offset making it fit into the
first IOV this was not done. Consequently, in this case configure the
PACK_ROW_LENGTH accordingly.
v2: fix whitespace issues
This fixes a number of piglits:
arb_copy_image-targets (for texture_2d source or dest, non-compressed)

This copy of the bind-flags should not be used, as they are a duplicate
