In core profile, we support up to 16 viewports. However, in the
majority of cases, only 1 of them is actually used - we only need
the others if the last shader stage prior to the rasterizer writes
gl_ViewportIndex.
Processing all 16 viewports adds additional CPU overhead, which hurts
CPU-intensive workloads such as Glamor. This meant that switching to
core profile actually penalized Glamor to an extent, which is
unfortunate.
This patch tracks the number of relevant viewports, switching between
1 and ctx->Const.MaxViewports if gl_ViewportIndex is written. A new
BRW_NEW_VIEWPORT_COUNT flag tracks this. This could mean re-emitting
viewport state when switching, but hopefully this is offset by doing
1/16th of the work in the common case. The new flag is also lighter
weight than BRW_NEW_VUE_MAP_GEOM_OUT, which we were using in one case.
According to Eric Anholt, x11perf -copypixwin10 performance improves by
11.5094% +/- 3.10841% (n=10) on his Skylake.

We'll need to use scissoring to restrict fragments to the viewport
soon. It seems harmless to include it generally, so let's do that.

Change references to gl_framebuffer::Width, Height, MaxNumLayers
and Visual::samples to use the _mesa_geometry_ convenience functions
for those places where the geometry of the gl_framebuffer is needed
(in contrast to the geometry of the intersection of the attachments
of the gl_framebuffer).
This patch is to pave the way to enable GL_ARB_framebuffer_no_attachments
on Gen7 and higher in i965.

It's been merged into brw_state_flags::brw for simplicity and
efficiency.

Most of the dirty flags were listed in some arbitrary order. Some used
bonus parenthesis. Some put multiple flags on one line, others put one
per line. Some used tabs instead of spaces...but only on some lines.
This patch settles on one flag per line, in alphabetical order, using
spaces instead of tabs, and sheds the unnecessary parentheses.
Sorting was mostly done with vim's visual block feature and !sort,
although I alphabetized short lists by hand; it was pretty manual.

Currently MaxViewports is still 1, so this won't affect any change.

This makes brw_context inherit directly from gl_context; that was the
only thing left in intel_context.

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.

I want to make brw_state_dump.c handle more than just the last
statechange, so I want to keep track of what's in the batch state. By
using AUB file numbering for most of these packets, this may be
reusable for aub dumping.

The scissor state was incorrectly in a .prepare function instead of
.emit, so the packet would end up in the batch before the
STATE_BASE_ADDRESS. It appears that this doesn't actually hurt, as
the scissor address gets dereferenced according to the current SBA at
draw time.

Now that all the dynamic state is streamed through the top of the
batchbuffer, we can cut out many of our relocations to that state by
using the base address.

This should make it easier to cross-reference the code and hardware
documentation, as well as clear up any confusion on whether constants
like CMD_3D_WM_STATE mean WM_STATE (pre-gen6) or 3DSTATE_WM (gen6+).
This does not rename any pre-gen6 defines.
