[ES] Fixed loading of OpenGL ES core API

Browse source 
eglGetProcAddress cannot be used to retrieve
entry points of core functions. Instead, we
use [DllImport] for core functions and function
pointers for extension functions.

    [Rewrite] Remove calli prototypes

    When a function is called indirectly via a function pointer, its
    prototype is not required (the prototype is added as a callsite at the
    calli invocation.) Removing these prototypes reduces binary size by
    roughly 400KB.

    [Rewrite] Call DllImports directly

    When a function does not have an allocated slot (i.e. slot = -1), then
    we will call its DllImport signature directly.

commit 9a5313e4b7afb10b698d255e4b5637887bf71cf3

    [Bind] Do not allocate slots for DllImports

commit 6ac5342409363cac0e59f9dc669948b319bd20a9
Author: thefiddler <stapostol@gmail.com>
Date:   Fri Mar 14 22:29:07 2014 +0100

    [Bind] Added option to use DllImports

    This is necessary for the core functionality of OpenGL ES, where
    eglGetProcAddress returns null or garbage (the latter on Android.)
