EGL: Implement the libglvnd interface for EGL (v3)

The new interface mostly just sits on top of the existing library.

The only change to the existing EGL code is to split the client
extension string into platform extensions and everything else. On
non-glvnd builds, eglQueryString will just concatenate the two strings.

The EGL dispatch stubs are all generated. The script is based on the one
used to generate entrypoints in libglvnd itself.

v2: [Kyle]
 - Rebased against master.
 - Reworked the EGL makefile to use separate libraries
 - Made the EGL code generation scripts work with Python 2 and 3.
 - Change gen_egl_dispatch.py to use argparse for the command line arguments.
 - Assorted formatting and style cleanup in the Python scripts.

v3: [Emil Velikov]
 - Rebase
 - Remove separate glvnd glx/egl configure toggles

+"""
+Contains a list of EGL functions to generate dispatch functions for.
+
+This is used from gen_egl_dispatch.py.
+
+EGL_FUNCTIONS is a sequence of (name, eglData) pairs, where name is the name
+of the function, and eglData is a dictionary containing data about that
+function.
+
+The values in the eglData dictionary are:
+- method (string):
+    How to select a vendor library. See "Method values" below.
+
+- prefix (string):
+    This string is prepended to the name of the dispatch function. If
+    unspecified, the default is "" (an empty string).
+
+- static (boolean)
+  If True, this function should be declared static.
+
+- "public" (boolean)
+    If True, the function should be exported from the library. Vendor libraries
+    generally should not use this.
+
+- extension (string):
+    If specified, this is the name of a macro to check for before defining a
+    function. Used for checking for extension macros and such.
+
+- retval (string):
+    If specified, this is a C expression with the default value to return if we
+    can't find a function to call. By default, it will try to guess from the
+    return type: EGL_NO_whatever for the various handle types, NULL for
+    pointers, and zero for everything else.
+
+method values:
+- "custom"
+    The dispatch stub will be hand-written instead of generated.
+
+- "none"
+    No dispatch function exists at all, but the function should still have an
+    entry in the index array. This is for other functions that a stub may need
+    to call that are implemented in libEGL itself.
+
+- "display"
+    Select a vendor from an EGLDisplay argument.
+
+- "device"
+    Select a vendor from an EGLDeviceEXT argument.
+
+- "current"
+    Select the vendor that owns the current context.
