st/mesa: fix pipe_get_transfer() call in fallback_copy_texsubimage()
Commit 1a339b6c71 caused us to take
a different path through the glCopyTexSubImage() code. The
pipe_get_transfer() call neglected to pass the texture's level, face
and slice info. So we were always transferring from the 0th mipmap
level even when the source renderbuffer was a non-zero mipmap level
in a texture.

NOTE: This is a candidate for the 7.10 branch.
i965: Make the brw_format_for_mesa_format table static const.
Once again, assuming the compiler is clever works out so poorly. The
generated code initialized the structure on the stack, then did a
lookup into it. This was a performance regression from
70c6cd39bd.

i965: Reuse existing program data when a new compiled program matches.
It's common in applications just before the advent of
EXT_separate_shader_objects to have multiple linked shaders with the
same VS or FS. While we aren't detecting those at the Mesa level, we
can detect when our compiled output happens to match an existing
compiled program.
This patch was created after noting the incredible amount of compiled
program data generated by Heroes of Newerth. It reduces the program
data in use at the start menu (replayed by apitrace) from 828kb to
632kb, and reduces CACHE_NEW_WM_PROG state flagging by 3/4. It
doesn't impact our rate of hardware state changes yet, because things
depending on CACHE_NEW_WM_PROG also depend on BRW_NEW_FRAGMENT_PROGRAM
which is still being flagged.

Use a typed struct to describe the native buffer and let the backends
map the native buffer to winsys_handle for
resource_from_handle/resource_to_handle.
targets/egl-static: allow st/mesa to be dynamically loaded
When shared glapi is not enabled, there are two glapi providers and we
cannot decide which one to link to at build time. It results in
unresolved symbols in st/mesa. This commit makes st/mesa a loadable
module when shared glapi is not enabled, and hopes that the apps will
link to one of the glapi providers (GL or GLES).
Build pipe drivers here instead of using those built by the
soon-to-be-removed targets/egl.

nv50,nvc0: prevent pushbuf flush during ctx reloc emission
Should unify this too, but will delay that until the planned
libdrm_nouveau/winsys changes which are likely to cause major
changes to this bo validation code too.
vbo: Don't discount stride == 0 for testing all varyings in VBOs.
In fixed function, stride == 0 (e.g. glColor4f() outside of the draw
call) would get turned into uniform inputs, which is why it was
ignored originally in this test. For shaders, drivers end up seeing a
need to upload stride == 0 data, and get confused by needing to upload
when vbo_all_varyings_in_vbos() returned true. In the 965 driver
case, it wouldn't bother to compute the min/max index, and uploaded
nothing if the min/max wasn't known.
We've talked about removing the ff stride=0-into-uniforms code, so
this check shouldn't be missed once that's gone.

vbo: Don't bother checking for stride == 0 for "any varying in a VBO".
We would still want to consider that data as being in a VBO even if we
managed to produce this case, which as far as I know we can't.

i965/gen6: Add a couple more packets to the nonpipelined workaround list.
All the packets chosen before came from grepping the pdf for
nonpipelined, and these two came from grepping for non.pipelined. We
could stand a review by looking at all packets emitted and identifying
what kind they are.
glsl: Flagged extension EXT_texture3D as "supported" in the builtin compiler.
Previously, the builtins in OES_texture_3D.{frag,vert} were only
compiling properly as a consequence of bug 38015, which allows
unsupported extensions to be enabled. This fix eliminates the builtin
compiler's reliance on bug 38015, so that bug 38015 can be fixed.
r600g: Add R8G8B8A8_UNORM to evergreen colorswap table
Fixes broken glTexImage2D with format=GL_RGBA since
1a339b6c71
The origin for this behaviour is that r600_is_format_supported
checks only against r600_state_inline.h tables not evergreens.
st/mesa: prefer native texture formats when possible.
If possible, we want to match the hardware format to what the app uses. By
doing so, we avoid the need for pixel conversions and therefore greatly speed
up texture uploads.
