As written, this test correctly raises an error for #elif being used
with an undefined macro (and not as an argument to "defined"). If the
preceding #if were '#if 1' then this diagnositc would correctly be
hidden. That allows code such as the following to not raise an error:

	#ifndef MAYBE_UNDEFINED
	#elif MAYBE_UNDEFINED < 5
	...
	#endif

So this test case is working as expected already. We add it here just
to improve test coverage.

The specification reserves any macro name containing two consecutive

this error for macro names that started with two underscores.

Fix the implementation to check for two underscores anywhere, and also

The GL spec says that luminance values are returned as (l, 0, 0, 1),
L/A values as (l, 0, 0, a) and intensity values as (i, 0, 0, 1).
Use the pixel transfer scale controls to implement that.
This fixes a few failures in the new piglit getteximage-formats
test when getting a compressed L or L/A image.

If color material mode is enabled, constant buffer entries related
to the material coefficients will depend on glColor.  So add
_NEW_CURRENT_ATTRIB to the bitset returned for material-related
constants in _mesa_program_state_flags().

This fixes a bug exercised by the new piglit draw-arrays-colormaterial
test.

Note: This is a candidate for the 7.11 branch.

This hasn't been needed so far since none of the core Mesa code paths
that call ctx->Driver.AllocTextureImageBuffer() are used with the
state tracker.  That will change in upcoming patches.
Note that this function duplicates some code seen in the st_TexImage()
function.  That can be cleaned up later.

The target, level and texObj can be obtained through the texImage
parameter.  We could make similar changes for the TexImage() hooks too.

It's part of pb_buffer already.

It may happen when two drivers share one winsys.

The formula we were previously using for asinh:

    asinh x = ln(x + sqrt(x * x + 1))

is numerically unstable: when x is a large negative value, the quantity

    x + sqrt(x * x + 1)

is a small positive value (on the order of 1/(2|x|)).  Since the
logarithm function is very sensitive in this range, any error in the
computation of the square root manifests as a large error in the
result.

This patch changes to the equivalent formula:

    asinh x = sign(x) * ln(abs(x) + sqrt(x * x + 1))

which is only slightly more expensive to compute, and is numerically
stable for all x.
