GPencil: Avoid tautology assignment

This is considered a warning which is usually promoted to
error in developers' environment.

Probably worth adding an assert or so, if possible?

CMake: Default to C11 for Clang and GCC

The option WITH_C11 is gone, and C++ is defaulting to C++11 now,
so guess it's fine to assume we need C11 now.

This is technically what we use anyway, with all the re-definitions
of structs (like when we typedef anonymous struct in a header file
first, and them define it to a proper structure in implementation
file).

GPencil: Use proper enumerator type

Was using GpencilModifierType in type definition,
but rest of usage was using values from GpencilModifierTypeType.

Merge branch 'master' into blender2.8

Fix compilation errors and warnings with Clang-6

Cycles: Implmemented texture filtering for box mapping.

Python IO: Initial nodal shader support for import AND export.

That new bpy_extras' node_shader_utils module is remotely based on
existing addons' cycles_shader_compat module. It has some key
differences though:
- It is based on Principled shader, instead of the noodle combination
of half a dozen simpler shaders.
- It does not do any value conversion (like e.g. clamping, which was
only suited for FBX). Any conversion/adaptation is to be done
by each IO add-on.
- It extensively uses accessors to offer:
- Easy read/write of values, hiding all the hairy noodly nodes
(principled shader helps a lot here).
- lazy creation of most nodes on accessing (when generating a
material), which avoids getting unused nodes in final shader.
- We only use Principled BSDF so far though, which means some features
supported by previous system are not yet implemented in new one.

Note that, even though we support 'exporting' side of things, this will
only work for a very specific (and basic) kind of shader. This will have
to be clearly explained in end-user documentation.

Also, that code has had some basic testing, but most certainly needs a
lot more refinement.

As proof-of-concept, OBJ IO script will be updated to use that new
system after that commit.

GP: Expand properties material list

GP: Expand properties layer list

GP: Remove separator line in materials submenu

GP: Remove material submenu icons

The icons made too heavy for the UI

GP: Expand topbar layers list

GP: Make materials topbar list longer

GP: Reorganize topbar material selector

Cleanup: remove unused DerivedMesh code.

UI: use new 3D viewport navigation icons and image icon in add menu.

I had to make the viewport navigation icons a bit smaller in the SVG since
the edges were being clipped off, we only support 16x16 icons currently.
They are a bit blurry because of this.

UI: add first batch of monochrome icons designed by Andrzej Ambroz.

Currently only for simple commands like play, add, zoom, expand, etc.

UI: draw mono icons with button type text color, instead of area text color.

Fix blender_icons_update.py not working after mono icon changes.
