This adds support for tracking images, and binding them
to the GL context.
includes:
vrend_renderer: create texture when TBO is used as image
vrend_renderer: specify correct access to glBindImageTexture
v2:
vrend_renderer: invert glBindImageTexture layered logic
v3: fix decode macros (Gert pointed out for ssbo)
v4: add max image samples to the caps.
add image arrays.
use mask var outside loop (Gert)
change img_locs type to GLint and printf on fail (Gert)

This converts the image related opcodes, and tracks the used
images.
Images need some extensions for extra features:
ES_3_1_compatability is needed for r32f image support
shader_image_size for image size support
v2: image: fix missing emit for atomic,
use a shader req for images extension
extend cas_str - we overflowed this
v2.1: drop extra breaks, use decl last for range check (Tomeu)
v3: add indirect support,
drop pointless debug print (Gert)
use 512 in load path.

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
the value to be pixels.

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)
arb_get_texture_multisample/sample_position
arb_texture_rectangle/fbo-blit rect
arb_get_texture__sub_image-cubemap

These VREND_BIND_*-flags here are basically a subset of the
VIRGL_BIND_*-flags, with one custom flag added. So let's just use
those, and use an unused big from the others for the swizzle-flag.

Instead of having the features in separate named bool, convert it
to an array of bools indexed by an enum.
This is a straight mechanical patch, no code flows should change
and it doesn't change any functionality, it just refactors the
code to use the enum list and a bool array.
Future work should be a lot easier on this, so I'd like to
land it first.
v2: use lowercase enum, move debug_cb in as well.
rename tf2, sort list.

Otherwise, it'd be possible to generate evil commands from a rouge
guest-driver that can crash the VM.
This is a bit trickier than the previous one, because we were already
mixing calls to the OpenGL 3.0 version and the GL_NV_conditional_render
version, which indicates that this was previously only safe if *both*
were supported, that is OpenGL 3.0 *with* GL_NV_conditional_render.
Now, this code should match the caps we generate, which shouldn't give
any percieved feature-regressions or gl-versions supported.
v2: do not set have_gl_conditional_render if on GLES 3.0 or above.
