egl/wayland: Use roundtrips when awaiting buffer release

In get_back_bo, we use wl_display_dispatch_queue() to block and wait for
a buffer release event. However, not all Wayland compositors flush the
client socket on posting a buffer-release event, so by only blocking
client-side, we may block indefinitely, or at least need to wait for an
input event / frame completion to arrive for the compositor to flush.

We now use dispatch_queue as a first pass, but if our entire buffer pool
is exhausted, use a roundtrip (an immediately-triggered wl_callback) to
ensure that the compositor flushes out our release event immediately.

vbo: fix glVertexAttrib(index=0)

Depending on which extension or GL spec you read the behavior of
glVertexAttrib(index=0) either sets the current value for generic
attribute 0, or it emits a vertex just like glVertex().  I believe
it should do either, depending on context (see below).

The piglit gl-2.0-vertex-const-attr test declares two vertex attributes:
  attribute vec2 vertex;
  attribute vec4 attr;
and the GLSL linker assigns "vertex" to location 0 and "attr" to location 1.
The test passes.

But if the declarations were reversed such that "attr" was location 0 and
"vertex" was location 1, the test would fail to draw properly.

The problem is the call to glVertexAttrib(index=0) to set attr's value
was interpreted as glVertex() and did not set generic attribute[0]'s value.
Interesting, calling glVertex() outside glBegin/End (which is effectively
what the piglit test does) does not generate a GL error.

I believe the behavior of glVertexAttrib(index=0) should depend on
whether it's called inside or outside of glBegin/glEnd().  If inside
glBegin/End(), it should act like glVertex().  Else, it should behave
like glVertexAttrib(index > 0).  This seems to be what NVIDIA does.

This patch makes two changes:

1. Check if we're inside glBegin/End for glVertexAttrib()
2. Fix the vertex array binding for recalculate_input_bindings().  As it was,
   we were using &vbo->currval[VBO_ATTRIB_POS], but that's interpreted
   as a zero-stride attribute and doesn't make sense for array drawing.

No Piglit regressions.  Fixes updated gl-2.0-vertex-const-attr test and
passes new gl-2.0-vertex-attrib-0 test.

All of the coordinates and LOD args are integers for TXF. This mostly
doesn't matter, except for converting into a levelZero=true operation by
removing an explicit zero LOD. For the comparison against zero to work
properly, the sType of the instruction has to be set correctly.

i965: Stop using wm_prog_data->binding_table.render_target_start.

Render target surfaces always start at binding table index 0.
This is required for us to use headerless FB writes, which we
really want to do.  So, we'll never change that.

Given that, it's not necessary to look up a wm_prog_data field
which we already know contains 0.  We can drop the dependency in
brw_renderbuffer_surfaces (Gen4-5)...which was already confusingly
missing from gen6_renderbuffer_surfaces.

We don't need yet another set of flags.  The function already has access

i965: Make a BRW_NEW_FAST_CLEAR_COLOR dirty bit.

When changing fast clear colors, we need to emit new SURFACE_STATE
with the updated color at the next draw call.

Most things work today because the atoms that handle SURFACE_STATE
for images (mutable images, textures, render targets) also listen to
BRW_NEW_BLORP, causing us to re-emit these on every BLORP operation.
However, this is overkill - most BLORP operations don't require us
to re-emit SURFACE_STATE.

One case where this is broken today is a fast clear to a different
color followed by a non-coherent framebuffer fetch.  The renderbuffer
read atom doesn't listen to BRW_NEW_BLORP, and would not get the new
fast clear color.
