A drawable size of 0x0 means that we don't have buffers for a drawable yet,
not that we have a zero-sized buffer. Core mesa shouldn't be optimizing out
drawing based on buffer size, since the draw call could be what triggers
the driver to go and get buffers. As discussed in the referenced bug report,
the optimization was added as part of a scatter-shot attempt to fix a
different problem. There's no other example in mesa core of using the
buffer size in this way.

WebGL Aquarium in Chrome 24 actually hits this.
v2: Move to core Mesa (wisely suggested by Ian); only consider
components which actually exist.
v3: Use _mesa_format_has_color_component to determine whether components
actually exist, fixing alpha format handling.
v4: Add a comment, as requested by Brian. No actual code changes.

_ColorDrawBufferIndexes is defined as GLint* and using a GLuint*
will result in the first part of the conditional to be evaluated to
true always.
Unintentionally introduced by the following commit, this will result
in a driver segfault if one is using an old version of the piglit test

The intention here is to protect all authors, not just Brian Paul. I
believe that was already the sensible interpretation, but spelling it
out is probably better.
More practically, it also prevents people from accidentally copy &
pasting the license into a new file which says Brian is not liable when
he isn't even one of the authors.

We now have a separate dispatch table for begin/end that prevent these
functions from being entered during that time. The
ASSERT_OUTSIDE_BEGIN_END_WITH_RETVALs are left because I don't want to
change any return values or introduce new error-only stubs at this
point.

Previously we were storing the RasterDiscard flag (for
GL_RASTERIZER_DISCARD) in gl_context::TransformFeedback. This was
confusing, because we use the _NEW_TRANSFORM flag (not
_NEW_TRANSFORM_FEEDBACK) to track state updates to it, and because
rasterizer discard has effects even when transform feedback is not in
use.
This patch makes RasterDiscard a toplevel element in gl_context rather
than a subfield of gl_context::TransformFeedback.
Note: We can't put RasterDiscard inside gl_context::Transform, since
all items inside gl_context::Transform need to be pieces of state that
are saved and restored using PushAttrib and PopAttrib.

The spec says "Only ClearBufferiv should be used to clear
stencil buffers." and "Only ClearBufferfv should be used to clear
depth buffers." However, on the following page it also says:
"The result of ClearBuffer is undefined if no conversion between
the type of the specified value and the type of the buffer being
cleared is defined (for example, if ClearBufferiv is called for a
fixed- or floating-point buffer, or if ClearBufferfv is called
for a signed or unsigned integer buffer). *This is not an error.*"
Emphasis mine.
Fixes problems with piglit's clearbuffer-invalid-drawbuffer test.

From the EXT_transform_feedback spec:
Primitives can be optionally discarded before rasterization by calling
Enable and Disable with RASTERIZER_DISCARD_EXT. When enabled, primitives
are discared right before the rasterization stage, but after the optional
transform feedback stage. When disabled, primitives are passed through to
the rasterization stage to be processed normally. RASTERIZER_DISCARD_EXT
applies to the DrawPixels, CopyPixels, Bitmap, Clear and Accum commands as
well.
And the GL 3.2 spec says it applies to ClearBuffer* as well.

This introduces a new gl_color_union union and moves the current
ClearColorUnclamped to use it, it removes current ClearColor completely and
renames CCU to CC, then all drivers are modified to expected unclamped floats instead.
also fixes st to use translated color in one place it wasn't.

These functions clear color/depth/stencil buffers with a value that's
passed to the function, rather than the context clear values.
For now these functions are implemented in terms of the existing
ctx->Driver.Clear() hook. In the future when we have non-normalized
integer and unsigned integer color buffer formats we'll need new
driver hook(s) to pass int and uint clear values to the driver.
Note: these functions are not hooked into the dispatch table at this time.
