Considering fbdev as an in-kernel window system,
- opening a device opens a connection
- there is only one window: the framebuffer
- fb_var_screeninfo decides window position, size, and even color format
- there is no pixmap
Now EGL is built on top of this window system. So we should have
- the fd as the handle of the native display
- reject all but one native window: NULL
- no pixmap support
modeset support is still around, but it should be removed soon.
The system routine requires m0 be reserved for saving off architectural
state. Moved the allocation to start at 2 instead of 0.

Previously, if max_depth were 1, the following code would see the
first if-statement (correctly) not get flattened, but the second
if-statement would (incorrectly) get flattened:
void main()
{
if (a)
gl_Position = vec4(0);
if (b)
gl_Position = vec4(1);
}
This is because the visit_leave(ir_if*) method would not decrement the
depth before returning on the first if-statement.
NOTE: This is a candidate for the 7.10 and 7.11 branches.

Typically this was done by having a surface creation function fail if
the format was not supported.
However, in some situations when changing hardware surface formats,
it's desirable to do this check before attempting costly readback operations.
Also updated the surface_redefine interface.
Bump minor.

Blending and maybe even alpha-test don't work with those formats.
Only supporting RGBA, BGRA, RGBX, BGRX.
NOTE: This is a candidate for the 7.10 and 7.11 branches.
Remove set_event_handler() and pass the event handler with
native_get_XXX_platform(). Add init_screen() so that the pipe screen is
created later. This way we don't need to pass user_data to
create_display().
If we happened to allocate a texture result (or other vector) to the
highest hardware register slot, and we were in 16-wide, we would
under-count the registers used and potentially wrap around to g0 if
that allocation crossed a 16-register block boundary. Bad rendering
and hangs ensued.

When the fill mode is PIPE_POLYGON_MODE_LINE we were basically
converting the polygon into triangles, then drawing the outline of all
the triangles. But we really only want to draw the lines around the
perimeter of the polygon, not the interior lines.
NOTE: This is a candidate for the 7.10 branch.
In gen6 and above, clip distances 0-3 are written to message register
3's xyzw components, and 4-7 to message register 4's xyzw components.
Therefore when when writing the clip distances we need to examine the
lower 2 bits of the clip distance index to see which component to
write to.
emit_vertex_write() was examining the lower 3 bits, causing clip
distances 4-7 not to be written correctly.
Fixes piglit test vs-clip-vertex-01.shader_test
Evergreen+ don't support multi-writes so we need to emulate
it in the shader. Fixes the following piglit tests:

In intel_draw_buffer, there exists a workaround to prevent
_mesa_update_framebuffer from creating a swrast depth wrapper when
using separate stencil. This commit fixes the workaround, which was
incomplete for s8z24 texture renderbuffers.
Fixes fbo-blit-d24s8 on gen5 with separate stencil manually enabled.

Since all infrastructure is now in place to support packed
depth/stencil renderbuffers when using separate stencil, there is no
need for special cases when separate stencil is enabled.

Also, in order to coerce intel_update_tex_wrapper_regions() to
allocate the hiz region, alter intel_update_tex_wrapper_regions() to

This prevents code duplication in the next commit.
