Make console message more clear for --scene argument

install_deps: make c++11 building mandatory on blender2.8 branch.

Merge branch 'master' into blender2.8

Fix T49623: Immediately crash trying to render attached file in Cycles

Original fix in this area was not really complete (but was the safest at
the release time). Now all the crazy configurations of slots going out
of sync should be handled here.

install_deps.sh: remove libglewmx from deb for now, the package is broken in deb testing...

install_deps.sh: first attempt to support cxx11.

For now, we merely add an option that sets CXXFLAGS envvar with
'--std=c++11' option.

There is no check done to ensure compatibility with the system
libraries, mainly because:
- It is all but trivial to get this information in a generic and
reliable way.
- Currently even cutting edge distributions may still distribute some c++98
libraries.
- With recent stdlibc++, both ABIs are supported together, which means
that incompatibilities are rather unlikely.

To summarize: if your system is recent and built with gcc-5.1 or more,
you should not experience too much troubles with c++11.

Gawain: add immRect utility functions (replaces legacy glRect)

Caller is responsible for setting up vertex format, binding a shader program, and setting the color *before* calling immRect.

OpenGL animation: Fix stupid mistake form previous commit

Flagging of pool to cancel was done in the wrong place, making last
frames missing in the final video.

Fix viewport camera gets out of sync in certain cases

It was possible to have two viewports opened and start using Ctrl-0
to make different objects an active camera for the viewport. This
worked fine for viewports which had decoupled camera from the scene,
but if viewport was locked to scene camera it was possible to run into
situation when two different viewports are locked to scene camera but
had different v3d->camera pointers.

OpenGL render: Fix missing file output after pressing Esc

Apparently, the whole G.is_break is not used by OpenGL render, meaning
this flag will not be clear before running the operator. This was
causing missing file output after pressing Esc once for the rest of
Blender session.

OpenGL: remove GLSL support query (it's always supported)

remove call to GLSL support query (it's always supported)

Reworked logic in the one place that still called this. Deleted the "GLSL not supported" fallback.

(equivalent to rB78abbdf26451 on blender2.8 branch)

BGE: remove calls to GLSL support query (it's always supported)

Reworked logic in the few places that still called this. Deleted the "GLSL not supported" fallbacks.

Also removed some nearby checks for ARB_multitexture and OpenGL 1.1. Blender 2.77 removed checks like this, but game engine still has some.

OpenGL: plug new matrix system into shaders (WIP)

Built-in shaders now use uniforms instead of legacy built-in matrices. So far I only hooked this up for new immediate mode.

We use the same matrix naming convention as OpenGL, but without the gl_ prefix, e.g. gl_ModelView becomes ModelView.

Right now it can skip the new matrix stack and use the legacy built-in matrices app-side. This will help us transition gradually from glMatrix functions to gpuMatrix functions.

Still some work to do in gpuBindMatrices. See TODO comments in gpu_matrix.c for specifics.

OpenGL: Draw dividers in space_file with the new immediate mode
