move_uniform_array_access_to_pull_constants() and setup_pull_constants()
both have two parts:
1. Decide which UNIFORM registers to demote to pull constants, and
assign locations.
2. Mechanically rewrite the instruction stream to pull the uniform
value into a temporary VGRF and use that, eliminating the UNIFORM
file access.
In order to support pull constants in SIMD16 mode, we will need to make
decisions exactly once, but rewrite both instruction streams.
Separating these two tasks will make this easier.
This patch introduces a new helper, demote_pull_constants(), which
takes care of rewriting the instruction stream, in both cases.
For the moment, a single invocation of demote_pull_constants can't
safely handle both reladdr and non-reladdr tasks, since the two callers
still use different names for uniforms due to remove_dead_constants()
remapping of things. So, we get an ugly boolean parameter saying
which to do. This will go away.

When demoting a variably indexed uniform array to pull constants, we
only recorded the location for the base of the array (element 0).
Recording locations for all array elements is a trivial amount of code
and will make subsequent refactoring easier.

Previously, both move_uniform_array_access_to_pull_constants() and
setup_pull_constants() maintained stack-local arrays with this
information. Storing this information will allow it to be used from
multiple functions, allowing us to split and move code around.
We'll also eventually want to pass pull constant location information
to the SIMD16 compile. Saving this information will help us do that.
Unfortunately, the two functions *cannot* share the contents of the
array just yet. remove_dead_constants() renumbers all the UNIFORM
registers to be contiguous starting at zero, so the two functions
talk about uniforms using different names. We can't even remap them,
since move_uniform_array_access_to_pull_constants() deletes UNIFORM
registers that are only accessed with reladdr, so remove_dead_constants
can't even see them.
This situation will improve in the next few patches.

The SIMD8 compile will determine whether pull parameters are necessary.
If so, it will set prog_data->nr_pull_params to a value greater than 0.
brw_wm_fs_emit checks if nr_pull_params > 0 and skips the SIMD16 compile
altogether. So, this code should never occur.

Internally, much of the EGL code uses EGLNativeDisplayType,
EGLNativeWindowType, and EGLPixmapType. However, the EGLNative type
often does not match the variable's actual type.
The concept of EGLNative types are a bad match for Linux, as explained
below. And the EGL platform extensions don't use EGLNative types at all.
Those extensions attempt to solve cross-platform issues by moving the
EGL API away from the EGLNative types.
The core of the problem is that eglplatform.h can define each EGLNative
type once only, but Linux supports multiple EGL platforms.
To work around the problem, Mesa's eglplatform.h contains multiple
definitions of each EGLNative type, selected by feature macros. Mesa
expects EGL clients to set the feature macro approrpiately. But the
feature macros don't work when a single codebase must be built with
support for multiple EGL platforms, *such as Mesa itself*.
When building libEGL, autotools chooses the EGLNative typedefs based on
the first element of '--with-egl-platforms'. For example,
'--with-egl-platforms=x11,drm,wayland' defines the following:
typedef Display* EGLNativeDisplayType;
typedef Window EGLNativeWindowType;
typedef Pixmap EGLNativePixmapType;
Clearly, this doesn't work well for Wayland and GBM. Mesa works around
the problem by casting the EGLNative types to different things in
different files.
For sanity's sake, and to prepare for the EGL platform extensions, this
patch removes from egl/main and egl/dri2 all internal use of the
EGLNative types. It replaces them with 'void*' and checks each explicit
cast with a static assertion. Also, the patch touches egl_gallium the
minimal amount to keep it compatible with eglapi.h.

dri2_initialize_x11_swrast() does a strange thing. For some extensions
it doesn't support, it sets the corresponding functions in

egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays.
The Wayland platform implemented its own dri2_wl_terminate(), which was
nearly a copy of the common one.
To implement the EGL platform extensions, we either need to dispatch
eglTerminate per display or define a common implementation for all
platforms. This patch chooses consolidation. It removes
dri2_wl_terminate() by folding it into the common dri2_terminate().
It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and
the switch statement because, unlike DRM and X11, Wayland's terminator
performed action even when EGL didn't own the native display. In the
inversion, I replaced `disp->PlatformDisplay == NULL` with
`dri2_dpy->own_device` because the two expressions are synonymous, but
the latter's meaning is clearer.

Each of the egl_dri2 platforms (except Android) prefix their function
names with "dri2", not "dri2_${platform}". This means many function
names have three separate definitions in the egl_dri2 directory: one in
each of platform_drm.c, platform_wayland.c, and platform_x11.c. For
example, each of the three files defines dri2_create_window_surface().
The name collisions make it difficult to review patches for correctness
("Is this patch hunk calling a platform_x11 function or a global
egl_dri2 function?"), complicate debugging, and confuse code navigation
tools.
For each function in platform_x11.c prefixed with 'dri2', this patch
changes its prefix to 'dri2_x11'. Likewise for platform_drm.c and
'dri2_drm'; and platform_wayland.c and 'dri2_wl'.
