intel: Fix rendering from textures after RenderTexture().
There's a serious trap for drivers: RenderTexture() does not indicate
that the texture is currently bound to the draw buffer, despite
FinishRenderTexture() signaling that the texture is just now being
unbound from the draw buffer.
We were acting as if RenderTexture() *was* the start of rendering and
that we could make texturing incoherent with the current contents of
the renderbuffer. This caused intel oglconform sRGB
Mipmap.1D_textures to fail, because we got a call to TexImage() and
thus RenderTexture() on a texture bound to a framebuffer that wasn't
the draw buffer, so we skipped validating the new image into the
texture object used for rendering.
We can't (easily) make RenderTexture() indicate the start of drawing,
because both our driver and gallium are using it as the moment to set
up the renderbuffer wrapper used for things like MapRenderbuffer().
Instead, postpone the setup of the workaround render target miptree
until update_renderbuffer time, so that we no longer need to skip
validation of miptrees used as render targets. As a bonus, this
should make GL_NV_texture_barrier possible.
(This also fixes a regression in the gen4 small-mipmap rendering since
3b38b33c1648b07e75dc4d8340758171e109c598, which switched
set_draw_offset from image->mt to irb->mt but didn't move the irb->mt
replacement up before set_draw_offset).
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44961
NOTE: This is a candidate for the 8.0 branch.

intel: Replace intel_texture_image::stencil_irb with intel_mipmap_tree::stencil_mt [v3]
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).
5. Read and test stencil data at (level=x2, layer=y2).
Test B:
1. Create a depthstencil texture.
2. Upload data into (level=x1,layer=y1).
3. Upload data into (level=x2,layer=y2).
4. Read and test stencil data at (level=x1, layer=y1).
5. Read and test stencil data at (level=x2, layer=y2).
v2:
Only allocate stencil miptree if intel->must_use_separate_stencil,
because we don't make the conversion from must_use_separate_stencil to
has_separate_stencil until commit
intel: Use separate stencil whenever possible
v3:
Don't call ChooseNewTexture in intel_renderbuffer_wrap_miptree() in
order to determine the renderbuffer format. Instead, pass the format as
a param to that function.

intel: Convert from GLboolean to 'bool' from stdbool.h.
I initially produced the patch using this bash command:
for file in {intel,i915,i965}/*.{c,cpp,h}; do [ ! -h $file ] && sed -i
's/GLboolean/bool/g' $file && sed -i 's/GL_TRUE/true/g' $file && sed -i
's/GL_FALSE/false/g' $file; done
Then I manually added #include <stdbool.h> to fix compilation errors,
and converted a few functions back to GLboolean that were used in core
Mesa's function pointer table to avoid "incompatible pointer" warnings.
Finally, I cleaned up some whitespace issues introduced by the change.

intel: make intel_texture_image a subclass of swrast_texture_image
We need to subclass swrast_texture_image because if we use swrast for
fallback rendering, we'll need to have swrast_texture_image objects.

intel: Clarify first_level/last_level vs baselevel/maxlevel by deletion.
This has always been ugly about our texture code -- object base/max
level vs intel object first/last level vs image level vs miptree
first/last level. We now get rid of intelObj->first_level which is
just tObj->BaseLevel, and make intelObj->_MaxLevel clearly based off
of tObj->_MaxLevel instead of duplicating its code (incorrectly, as
image->MaxLog2 only considers width/height and not depth!)
