This fixes a regression from a8cf4b6acf
The problem occured when two successive glDrawArrays calls accessed
subsequent elements in user-space arrays. The user-space array
from the first call wasn't being grown to accomodate the second
draw call's elements.

While the program won't successfully link in the end, this avoids
possible assertion failure in the driver during linking if
this->result isn't initialized with something already.

We now raise an GL_INVALID_ENUM in glBegin() if mode is illegal, as was
done in Yuanhan Liu's original patch.
Take geometry shaders support into account too.

Checking if the paints are opaque in renderer_validate_blend() does not
work. We could be drawing images. Remove the check from
renderer_validate_blend() and take image drawing into consideration in
blend_use_shader().
The bug was introduced by 3f0a966807,
which affects the lookup demo.
vg_context_is_object_valid() checks if a handle is valid by checking if
the handle is a valid key of the object hash table. However, the keys
of the object hash table were object pointers.
Fix vg_context_add_object() to use the handles as the keys so that
vg_context_is_object_valid() works. This bug was introduced by
99c67f27d3.
Use _mesa_set_enable() to avoid a redudant context lookup.
Need to disable the texture target in decompress_texture_image() so the
unit isn't still enabled after glGetTexImage() returns. Arguably, the
meta restore code should do this, but it doesn't.

If we're generating a mipmap for an sRGB texture we need to bypass
sRGB->linear conversion. Otherwise the destination mipmap level
(drawn with a textured quad) will have the wrong colors.
If we can't turn of sRGB->linear conversion (GL_EXT_texture_sRGB_decode)
we need to use the software fallback for mipmap generation.
Note: This is a candidate for the 7.11 branch.
The 1-bit alpha channel was incorrectly encoded. Previously, any non-zero
alpha value for the ubyte alpha value would set A=1. Instead, use the
most significant bit of the ubyte alpha to determine the A bit. This is
consistent with the other channels and other OpenGL implementations.
Note: This is a candidate for the 7.11 branch.

builtin_stubs.cpp is only supposed to be used for builtin_compiler. It
contains a stub version of _mesa_glsl_initialize_functions() that does
nothing.
libglsl.a already contains builtin_function.cpp, the generated file that
contains a version of _mesa_glsl_initialize_functions() that actually
initializes all the built-in functions.
By mistakenly linking to builtin_stubs, glsl_compiler and glsl_test are
unable to compile any shaders that use built-in functions.

Since Mesa is now capable of supporting up to 8 clipping planes
instead of 6, this patch updates Gallium internals to support 8
clipping planes as well.
