_mesa_update_framebuffer now operates on arbitrary read and draw framebuffers.
This allows BlitNamedFramebuffer to update the state of its arbitrary read and
draw framebuffers.

This splits off the (still) rather large chunk that is
get_texture_for_framebuffer into lots of smaller functions specialized to
service the wide variety of unique needs of *FramebufferTexture* entry points.
The result is much cleaner because, rather than having a pile of branches and
confusing conditions (like the boolean layered), the uniqueness is baked into
the entry points. The entry points know whether or not they are layered or use
a textarget.
[Fredrik: - Mention the value of <textarget> in the error message.
- Rename check_zoffset to check_layer, and zoffset to layer.
The zoffset parameter was renamed to layer in
ARB_framebuffer_object.
- Make layered a GLboolean since the value is visible to the API.
- Remove EXT suffixes in refactored code.
- Whitespace fixes.]

This moves a few blocks around so that the control flow is more obvious. If
the texture is 0, just return true at the beginning of the function.
Likewise, if the texObj is NULL, return true at the beginning of the function
as well.
[Fredrik: Fix the texObj NULL check]

This way we can pass in a vertex shader and yet have the pipeline emit an
empty 3DSTATE_VS packet. We need this for meta because we need to trick
the compiler into not deleting our inputs but at the same time disable the
VS so that we can use a rectlist. This should go away once we actually get
SPIR-V.
This is rather crude but it at least makes sure that all the render targets
get flushed at the end of the pass. We probably actually want to do
somthing based on image layout traansitions, but this will work for now.
This is by no means a complete solution to the binding table problems.
However, it does make texturing actually work. Before, we were texturing
from the render target since they were both starting at 0.
Some bits were already there for texture views but some were missing.
In particular for cube map views things needed to change a bit.
For simplicity I ended up removing the separate face addr bit (just use
the z bit) - cube arrays didn't use it already, so just follow the same
logic there. (In theory using separate bits could allow for better hash
function but I don't think anyone ever did some measurements of that so
probably not worth the trouble, if we'd reintroduce it we'd certainly
wanted to use the same logic for cube arrays and cube maps.)
Also extend the seamless cube sampling to cube arrays - as there were no
piglit failures before this is apparently untested, but things now generally
work quite the same for cube textures and cube array textures so there
hopefully shouldn't be any trouble...
49 new piglits, 47 pass, 2 fail (both due to fake multisampling).
v2: incorporate Brian's feedback, add sampler view validation,
function rename, formatting fixes.

All the functionality was pretty much there, just not tested.
Trivially fix up the missing pieces (take target info from view not
resource), and add some missing bits for cubes.
Also add some minimal debug validation to detect uninitialized target values
in the view...
49 new piglits, 47 pass, 2 fail (both related to fake multisampling,
not texture_view itself). No other piglit changes.
v2: move sampler view validation to sampler view creation, update docs.
