When clearing a GL_LUMINANCE_ALPHA buffer, for example, we need to convert
the clear color (R,G,B,A) to (R,R,R,A). We were doing this for texture border
colors but not renderbuffers. Move the translation function to st_format.c
and share it.
This fixes the piglit fbo-clear-formats test.

Before we were looping to nr_samplers, which is the number of fragment
samplers, not vertex samplers.

The extra length is the size of the request *minus* the size of the

xGLXChangeDrawableAttributesSGIXReq follows the GLXVendorPrivate header
with a drawable, number of attributes, and list of (type, value)
attribute pairs. Don't forget to put the number of attributes in there.
I don't think this can ever have worked.

emit_adjusted_wpos() needs separate x,y translation values. If we
invert Y, we don't want to effect X.

This fixes a problem when glDrawBuffers(GL_NONE). The fragment program
was writing to color output[0] but OutputsWritten was 0. That led to a
failed assertion in the Mesa->TGSI translation code.

(cherry picked from commit 9351ef7a44)
In general, we have to negate in immediate values we pass in because
the src1 negate field in the register description is in the bits3 slot
that the 32-bit value is loaded into, so it's ignored by the hardware.
However, the src0 negate field is in bits1, so after we'd negated the
immediate value loaded in, it would also get negated through the
register description. This broke this VP instruction in the position
calculation in civ4:
MAD TEMP[1], TEMP[1], CONST[256].zzzz, CONST[256].-y-y-y-y;

The rvalue of the returned value can be NULL if the shader says
'return foo();' and foo() is a function that returns void.
Existing GLSL specs do *NOT* say that this is an error. The type of
the return value is void. If the return type of the function is also
void, then this should compile without error. I expect that future
versions of the GLSL spec will fix this (wink, wink, nudge, nudge).
