`EGLDisplay` variables (the opaque Khronos type) have mostly been
consistently called `dpy`, as this is the name used in the Khronos
specs.
However, `_EGLDisplay` variables (our internal struct) have been
randomly called `dpy` when there was no local variable clash with
`EGLDisplay`s, and `disp` otherwise.
Let's be consistent and use `dpy` for the Khronos type, and `disp`
for our struct.

dri2_fallback_swap_interval() currently used to stub out swap interval
support in Android backend does nothing besides returning EGL_FALSE.
This causes at least one known application (Android Snapchat) to fail
due to an unexpected error and my loose interpretation of the EGL 1.5
specification justifies it. Relevant quote below:
The function
EGLBoolean eglSwapInterval(EGLDisplay dpy, EGLint interval);
specifies the minimum number of video frame periods per buffer swap
for the draw surface of the current context, for the current rendering
API. [...]
The parameter interval specifies the minimum number of video frames
that are displayed before a buffer swap will occur. The interval
specified by the function applies to the draw surface bound to the
context that is current on the calling thread. [...] interval is
silently clamped to minimum and maximum implementation dependent
values before being stored; these values are defined by EGLConfig
attributes EGL_MIN_SWAP_INTERVAL and EGL_MAX_SWAP_INTERVAL
respectively.
The default swap interval is 1.
Even though it does not specify the exact behavior if the platform does
not support changing the swap interval, the default assumed state is the
swap interval of 1, which I interpret as a value that eglSwapInterval()
should succeed if called with, even if there is no ability to change the
interval (but there is no change requested). Moreover, since the
behavior is defined to clamp the requested value to minimum and maximum
and at least the default value of 1 must be present in the range, the
implementation might be expected to have a valid range, which in case of
the feature being unsupported, would correspond to {1} and any request
might be expected to be clamped to this value.
Fix this by defaulting dri2_dpy's min_swap_interval, max_swap_interval
and default_swap_interval to 1 in dri2_setup_screen() and let platforms,
which support this functionality set their own values after this
function returns. Thanks to patches merged earlier, we can also remove
the dri2_fallback_swap_interval() completely, as with a singular range
it would not be called anyway.
v2: Remove dri2_fallback_swap_interval() completely thanks to higher
layer already clamping the requested interval and not calling the
driver layer if the clamped value is the same as current.

Since commit 0a606a400f ("egl: add eglSwapBuffersWithDamageKHR"),
Android has been broken because the function eglSwapBuffersWithDamageKHR
is provided regardless of the extension being present. Also, the Android
meta-EGL always advertises the extension regardless of the underlying
EGL implementation. As there doesn't seem to be a simple way
conditionally make the EGL function ptr NULL, just implement a brain
dead version of eglSwapBuffersWithDamage{KHR,EXT}.

Chromium defined a new GL extension (that isn't registered with Khronos).
We need to add an EGL extension for it, so we can migrate ChromeOS on
Intel systems to use EGL instead of GLX.
http://git.chromium.org/gitweb/?p=chromium/src/third_party/khronos.git;a=commitdiff;h=27cbfdab35c601f70aa150581ad1448d0401f447
The EGL_CHROMIUM_sync_control extension is similar to the GLX extension
OML_sync_control, but only defines one function,
eglGetSyncValuesCHROMIUM, which is equivalent to glXGetSyncValuesOML.

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.
