The ARB_direct_state_access specification says (as of 2015.02.05):
"Interactions with OpenGL 4.3 or ARB_framebuffer_no_attachments
If neither OpenGL 4.3 nor ARB_framebuffer_no_attachments are supported,
ignore the support for NamedFramebufferParameteri and
GetNamedFramebufferParameteriv."
This commit adds stubs for these entry points.

Mesa's ClearBuffer framework is very complicated and thoroughly married to the
object binding model. Moreover, the OpenGL spec for ClearBuffer is also very
complicated. At some point, we should implement buffer clearing for arbitrary
framebuffer objects, but for now, we will just wrap ClearBuffer.

Previously, we used _mesa_update_state to update the currently bound
framebuffers prior to performing a blit. Now that _mesa_blit_framebuffer
uses arbitrary framebuffers, _mesa_update_state is not specific enough.

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

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.

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.
