Merge branch 'master' into soc-2014-viewport_fx

I have resolved some differences, for instance selection code which was more or less a stub, to be
the same as master. This will have to be fixed later.

Fix compilation on linux (Ubuntu 14.04 used here).

need to call releaseNativeHandles in GHOST_WindowX11's destructor, as well as some additional checks in GHOST_ContextGLX's destructor

fix initial window size being too large for OSX/X11 on multiple monitors (check for X11 being used instead of not APPLE and not WIN32)

oops, some typos made it into the GLX context commit

removed some accidentally added backup files

Merge branch 'soc-2014-viewport_fx' of git.blender.org:blender into soc-2014-viewport_fx

[Revision] GHOST Context Refactor for X11 (Also can compile GHOST X11 on OSX)
This is much like the CGL context in that it is fairly preliminary and does not have all the features of EGL or WGL contexts yet.
In order to work on this on OSX, some minor changes were made to CMake to link with X11 on OSX

some readability edits for ghost context classes
also added code to clear screen immediately after context creation, similar to how it is done for glX

removed apparent overly verbose conversion of int to bool in GHOST_C-api.cpp

fix: xdnd module did not compile on OSX without setting the location of X11 include files

Moved and deleted some code from GHOST Cocoa
moved locale query to the intern/locale module
deleted some odd code that did not appear to be actually used relating to command line arguments

[OpenGL Policy] BlendFuncSeparate defaults to GL_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_ZERO

Only set the blend func if the coefficients are different. Return them to the defaults when done.

Note: Fairly confident that Blender and the standalone Cycles renderer are correct, but that both the embedded and standalone game engine will need more testing.

Note: Do we actually want the default to be: GL_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_ONE_MINUS_SRC_ALPHA?

OpenGL Extension Shims

A few things are going on with these "shims":
* OpenGL 2.0 and GLEW_ARB_shader_objects are subtly different.
* Some extensions come in ARB and OES flavors.
* GenerateMipmaps needs a workaround on ATI.
* gpu_buffer_start_update and gpu_buffer_finish_update make usage of buffer objects a bit more abstract

Any use of a shimmed function directly without the shim is caught by GPU_deprecated.h

There are also some other changes that are not related to shims that came along for the ride.

Made a mistake when rewriting GPU_material_construct_end to return bool.

#if 0'd out all of GPU_deprecated.h and turned on GPU_MANGLE_DEPRECATED by default.

Will add functions and symbols back as work progresses.

Since bgl.c uses OpenGL directly like source/blender/gpu, it disables GPU_MANGLE_DEPRECATED.

Added getNumOfAASamples to GHOST_IWindow interface.

I was going to use it for something, but decided to use glGetIntegerv(GL_SAMPLES, &i) instead.
It may be the case that neither this nor stereoVisual should be cached.

Fixed documentation of GHOST_GetSwapInterval to match new interface
