svga: call u_default_redefine_user_buffer() to fix failed assertion
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.

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 3f0a966807f03a364edea0272ddf45f08ab7ce4f,
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.
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.

Gallium: remove unnecessary ifdef for MAX_CLIPPED_VERTICES.
draw_pipe_clip.c contained an ifdef to ensure that its local
definition of MAX_CLIPPED_VERTICES would not take effect if the global
MAX_CLIPPED_VERTICES (defined in src/mesa/main/config.h) was already
defined. This was unnecessary because draw_pipe_clip.c doesn't
directly or indirectly include src/mesa/main/config.h. Removed the
ifdef to reduce confusion.

gallium: move clear paths from rgba to a pointer to a color union (v2)
This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in
patch.

Pass an explicit surface format as we do with pipe_put_tile_rgba_format().
This fixes the piglit fbo-srgb-blit test. With GL_EXT_framebuffer_sRGB we
override the resource's format with an explicit format (linear vs. sRGB).
We need to do so both when getting and putting tiles.

r600g: take constantly interpolated values into a/c
We could constant interpolated values now and set have_perspective

TGSI CONSTANT interpolation is just flat, and we just read the values
direct from the LDS into the GPR without doing any interpolation on them.
This is needed to pass integer types into the fragment shader.

softpipe: fix blending for luminance/intensity surfaces
If we're drawing to a luminance, luminance/alpha or intensity surface
we have to adjust (rebase) the fragment/quad colors before writing them
to the tile cache. The tile cache always stores RGBA colors but if
we're caching a L/A surface (for example) we need to be sure that R=G=B
so that subsequent reads from the surface cache appear to return L/A
We previously had a special case for RGB (no alpha) surfaces. This
change generalizes that for the other base formats.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40408, but sRGB
formats are still failing. That'll be addressed in a later patch.
