We now support version 2 of the virgl_renderer_callbacks struct, so
update the test to check for an unsupported version. Use
VIRGL_RENDERER_CALLBACKS_VERSION + 1 as the test version to ensure we
don't fail this test again when we update the struct in the future.
Fixes: test_virgl_init.virgl_init_cbs_wrong_ver

- virgl maps VIRGL_FORMAT_B8G8R8X8_UNORM to GL_RGBA8
- _mesa_choose_tex_format() maps GL_RGBA8 to
MESA_FORMAT_R8G8B8A8_UNORM or MESA_FORMAT_A8B8G8R8_UNORM or
MESA_FORMAT_B8G8R8A8_UNORM.
- it ends up in (gl_texture_image *)img->TexFormat
- then in intel (_DRIImage *) image->format.
- on create image, image->dri_format = driGLFormatToImageFormat() (to
ex: MESA_FORMAT_R8G8B8A8_UNORM -> __DRI_IMAGE_FORMAT_ABGR8888)
- on query, intel_lookup_fourcc() -> __DRI_IMAGE_FOURCC_ABGR8888 == GBM_FORMAT_ABGR8888.
For some reason, driGLFormatToImageFormat() doesn't map
MESA_FORMAT_A8B8G8R8_UNORM, so I only check the two possible values I
could find.

the protocol failed to handle larger shaders, this allow
the renderer to reassemble large shaders and recombined
the chunks before passing them to the GLSL translation.
This also enhances the renderer protocol to allow
for some more info in the shader object, and removes
the separate vs/gs/fs variants in favour of a type field
in the shader.
This fixes a number of issues with how transform feedback works
it does requires ARB_transform_feedback3 to work at all, but
hopefully this extension is widespread enough, if not we can
revisit later.
It uses transform feedback objects to store the stream out
state.
