Add Support for GL 4.3 (Bug 716) and ES 3.0 (Bug 717)

ES3 / GL4.3:

- Update all EGL, GLX, WGL and GL (desktop and mobile) khronos headers to latest version.
  - GL3/gl3* -> GL/glcorearb*

  - Explicitly preserve ES2_compatibility and ES3_compatibility in header,
    most extension grouping was removed in new headers.

  - Always load all GLHeader to ensure proper extension association across all profiles.

  - Unified method signatures

  - Added GL_EXT_map_buffer_range to core

  - Using common 'glMapBufferImpl(..)' for all glMapBuffer(..) and glMapBufferRange(..) impl.

  - Init necessary fields of GL instances via 'finalizeInit()' called by reflection, if exist.
    This allows removing initialization checks, i.e. for all buffer validations.

- BuildStaticGLInfo: Can handle new GL header structure, i.e. one CPP extenstion block incl. define + funcs.

- GLJavaMethodBindingEmitter: Simply print the

- No GL duplication due to new intermediate interfaces, see below

- OO lineare inheritance (Added GL2ES3, GL3ES3 and GL4ES3 intemediates):
  GLBase - GL - GL2ES2 - GLES2
  GLBase - GL - GL2ES2 - GL2GL3 - [ GL2, GL3 ]
  GLBase - GL - GL2ES2 - GL2ES3 - GL3ES3 - [ GL3 ]
  GLBase - GL - GL2ES2 - GL2ES3 - GL3ES3 - GL4ES3 - [ GLES3, GL4, .. ]

- Expose 'usable' intermediate interfaces GL3ES3 and GL4ES3 in GLBase/GLProfile/GLContext
  via is*() and get*().

- GLContext*:
  - isGL3core() is true if [ GL4, GL3, GLES3 ] (added GLES3)

  - Added ctxProfile argument to allow handling ES versions:
    - getMaxMajor(..), getMaxMinor(..), isValidGLVersion(..) and decrementGLVersion(..)
    - mapGLVersions(..) prepared for ES ARB/KHR validation

  - EGLContext checks ES3 (via old ctx's GL_VERSION)

- ExtensionAvailabilityCache adds GL_ES_Version_X_Y for ES.

- Prelim tests w/ Mesa 9.1.3
  GL Version     3.0 (ES profile, ES2 compat, ES3 compat, FBO, hardware) - OpenGL ES 3.0 Mesa 9.1.3 [GL 3.0.0, vendor 9.1.3 (Mesa 9.1.3)]

- TODO:
  - Use KHR_create_context in EGLContext.createContextARBImpl(..)
  - More tests (Mobile, ..)

+++

Misc:

- GLContext*:
  - Complete glAllocateMemoryNV w/ glFreeMemoryNV.
