* We have a symbol conflict as rtasm in
Mesa collides with rtasm in gallium.
* As us linking gallium and mesa together
is an edge case, lets just omit the rtasm
code from Mesa as we should be going

This is not as optimized as r600g - the MSAA compression is missing,
so r300g needs a lot of bandwidth (more than r600g to do the same thing).
However, if the bandwidth is not an issue for you, you can enjoy this
unoptimized MSAA support.
The only other missing optimization for MSAA is the fast color clear.
MSAA is enabled on r500 only, because that's the only GPU family I tested.
That said, MSAA should work on r300 and r400 as well (but you must set
RADEON_MSAA=1 to allow it, then turn MSAA on in your app or set GALLIUM_MSAA=n,
n >= 2, n <= 6)
I will enable the support by default on r300-r400 once someone (other than me)
tests those chipsets with piglit.
The supported modes are 2x, 4x, 6x.
The supported MSAA formats are RGBA8, BGRA8, and RGBA16F (r500 only).
Those 3 formats are used for all GL internal formats.
Tested with piglit. (I have ported all MSAA tests to GL2.1)
Fixes this build error on platforms not using GNU indent.

The OpenGL 3.2 core profile spec says:
"The following base internal formats from table 3.11 are
color-renderable: RED, RG, RGB, and RGBA. The sized internal formats
from table 3.12 that have a color-renderable base internal format
are also color-renderable. No other formats, including compressed
internal formats, are color-renderable."
The OpenGL 3.2 compatibility profile spec says (only ALPHA is added):
"The following base internal formats from table 3.16 are
color-renderable: ALPHA, RED, RG, RGB, and RGBA. The sized internal formats
from table 3.17 that have a color-renderable base internal format
are also color-renderable. No other formats, including compressed
internal formats, are color-renderable."
Table 3.12 in the core profile spec and table 3.17 in the compatibility
profile spec list SNORM formats as having a base internal format of RED,
RG, RGB, or RGBA. From this we infer that they should also be color
renderable.
The OpenGL ES 3.0 spec says:
"An internal format is color-renderable if it is one of the formats
from table 3.12 noted as color-renderable or if it is unsized format
RGBA or RGB. No other formats, including compressed internal
formats, are color-renderable."
In the OpenGL ES 3.0 spec, none of the SNORM formats have "color-
renderable" marked in table 3.12. The RGB I and UI formats also are not
color-renderable in ES3, but we'll save that change for another patch.
Both NVIDIA's closed-source driver (version 304.64) and AMD's
closed-source driver (Catalyst 12.6 on HD 3650) reject *all* SNORM
formats for renderbuffers in OpenGL 3.3 compatibility profiles.

This code now lives in an external tree.
For the next Mesa release fetch the code from the master branch
of this LLVM repo:

- skip the vertex buffer reallocation in flush and just use
the unsynchronized flag to get new memory.
- remove the cruft needed to get around the issues with the vertex buffer
reallocation in flush
- use pb_buffer instead of pipe_resource
This patch fixes intel_miptree_unmap_etc() (which decompresses ETC
textures to linear) to pay attention to map->x and map->y when writing
to the destination image. Previously these values were ignored,
causing the xoffset and yoffset parameters passed to
glCompressedTexSubImage2D() to be ignored.

- We should use a 3D transfer of size Width x 1 x NumLayers.
- We should use layer_stride instead of stride.
(even though they are likely to be equal with 1D array textures)

There was the fast path based on _mesa_format_matches_format_and_type
for GetTexImage, but it never worked, because the Mesa format we were testing
there was always compressed. Further testing showed that the fast path
had been completely broken.
In this commit, the somewhat limited helper util_create_rgba_texture is
no longer used and instead, custom code for the texture creation is added,
which tries to find the best matching RGBA8 format, so that we can hit
the fast path *always* if the read format is a variant of RGBA8 and supported
by the driver.
