For depthstencil textures using separate stencil, we embedded a stencil
buffer in intel_texture_image. The intention was that the embedded stencil
buffer would be the golden copy of the texture's stencil bits. When
necessary, we scattered/gathered the stencil bits between the texture
miptree and the embedded stencil buffer.
This approach had a serious deficiency for mipmapped or multi-layer
textures. Any given moment the embedded stencil buffer was consistent with
exactly one miptree slice, the most recent one to be scattered. This
permitted tests of type A to pass, but broke tests of type B.
Test A:
1. Create a depthstencil texture.
2. Upload data into (level=x1,layer=y1).
3. Read and test stencil data at (level=x1, layer=y1).
4. Upload data into (level=x2,layer=y2).

intel: Kill intel_mipmap_level::nr_images [v4]
For all texture targets except GL_TEXTURE_CUBE_MAP, the 'nr_images' and
'depth' fields of intel_mipmap_level were identical. In the exceptional
case, nr_images == 6 and depth == 1.
It is simple to determine if a texture is a cube or not, so the presence
of two fields here was not helpful. Worse, it was confusing. When we
eventually implement GL_ARB_texture_cube_map_array, this mess would have
become even more confusing.
This patch removes 'nr_images' and assigns to 'depth' a consistent
meaning: depth is the number of 2D slices at each miplevel. The exact
semantics of depth varies according to the texture target:
- For GL_TEXTURE_CUBE_MAP, depth is 6.
- For GL_TEXTURE_2D_ARRAY, depth is the number of array slices. It is
identical for all miplevels in the texture.
- For GL_TEXTURE_3D, it is the texture's depth at each miplevel. Its
value, like width and height, varies with miplevel.
- For other texture types, depth is 1.
As a consequence, parameters were removed from the following function
signatures:
intel_miptree_set_level_info
Remove 'nr_images'.
i945_miptree_layout
brw_miptree_layout_texture
brw_miptree_layout_texture_array

intel: Temporarily disable HiZ for textures
A great refactor thrashing begins after this commit for HiZ and separate
stencil. Removing code for texture HiZ will make that refactoring easier,
because then we don't have to maintain that code during the refactor.
To disable HiZ for textures, I've removed the hook in
intel_update_wrapper() that allocates a HiZ buffer when attaching a depth
texture to a framebuffer.
HiZ was broken for textures anyway, so there's no regression here.

intel: Fix swrast_render_start() for depthstencil buffers with separate stencil
1. Don't map the depthstencil buffer twice
Place a guard in intel_renderbuffer_map() to prevent a renderbuffer
from being mapped twice. This happened if a single buffer was attached to
the framebuffer's depth and stencil attachment points. (Interestingly,
because intel_map_renderbuffer_gtt() is idempotent, the double mapping did
not cause bugs for depthstencil buffers *without* separate stencil).
2. Stop overriding gl_framebuffer::_DepthBuffer,_StencilBuffer
Normally, if a depthstencil buffer is attached to the framebuffer's
depth attachment point, then _mesa_update_framebuffer() installs
a wrapper depth renderbuffer at gl_framebuffer::_DepthBuffer. Ditto for
the stencil attachment point and gl_framebuffer::_StencilBuffer
A depthstencil intel_renderbuffer with separate stencil contains hidden
depth and stencil renderbuffers, which are the *real* renderbuffers. In
order to force swrast to work, we were installing, in
brw_update_draw_buffer(), the hidden renderbuffers at
gl_framebuffer::_DepthBuffer and _StencilBuffer, thus overriding the
behavior of _mesa_update_framebuffer(). However, now that
intel_renderbuffer_map() is implemented with MapRenderbuffer(),
overriding _mesa_update_framebuffer's introduces bugs. This patch
removes the override code.
Fixes several Piglit tests on gen7.

mesa: Only update sampler uniforms that are used by the shader stage
Previously a vertex shader that used no samplers would get updated (by
calling the driver's ProgramStringNotify) when a sampler in the
fragment shader was updated. This was discovered while investigating
some spurious code generation for shaders in Cogs. The behavior in
Cogs is especially pessimal because it ping-pongs sampler uniform
settings:
glUniform1i(sampler1, 0);
glUniform1i(sampler2, 1);
draw();
glUniform1i(sampler1, 1);
glUniform1i(sampler2, 0);
draw();
glUniform1i(sampler1, 0);
glUniform1i(sampler2, 1);
draw();
// etc.
ProgramStringNotify is still too big of a hammer. Applications like
Cogs will still defeat the shader cache. A lighter-weight mechanism
that can work with the shader cache is needed. However, this patch at
least restores the previous behavior.
