Cycles: Fix KernelIntegrator padding to 16-byte boundary

Updated install_deps.sh to OSD 3.0.5 (and switch from git repo to download archive of sources).

Cycles Standalone: Add option to set the tile size from the command line

Since the optimal values depend on the device used, this option doesn't make much sense in the XML.
Therefore, it's now specified via the command line, just like the device itself.

Cycles: Correct maximum number of textures on pre-Kepler CUDA cards

Commit c96ae81160ad added three data textures and therefore removed three image texture slots, but the value in util_textures.h wasn't updated.

GPencil: Avoid segment fault if new stroke function is called without colorname

Merge branch 'master' into blender2.8

Conflicts:
source/blender/blenkernel/intern/library.c
source/blender/blenkernel/intern/particle.c

GPencil: Rename color name property to keep consistency in naming

Gawain: map vertex format to shader inputs

glBindAttribLocation does not take effect until the program is
re-linked. In other words I was doing it wrong!

New code gets attrib locations from program, then remembers the attrib
-> location mapping for subsequent draw calls.

The program and VertexFormat are not modified (makes threading and reuse
easier).

Gawain: fix compiler warnings

properly typed function parameters
pointer casting & arithmetic
ptrdiff_t formatting

OpenGL: invalidate buffers the modern way

There are older ways to give OpenGL hints about buffer invalidation, but
glInvalidateBufferData does exactly what we want. Use this function when
OpenGL 4.3 is available (Windows and proprietary Linux drivers).

Part of Gawain immediate mode.

Fix crash in id remapping of Graph editor.

dopsheet data pointer is not guaranteed to be set it seems...

Cycles: Use proper property getter

Attempt to fix previous commit for non-c++11 builds

Fix for isfinite breaking builds when WITH_CXX11 is enabled.

This happens when cmath.h is included after math.h in cpp code.
Kudos to Sergey for pointing this out.

Fix T48916: Proxy Custom File is broken

Fix T49027: Sequence uses too much memory when rendering scene with lots of movie strips

Now we free sequencer cache and close all unneeded FFmpeg handles when rendering.
This is the same logic as image sequence memory freeding.

CMake: Once again, don't use find_package to get hardcoded libraries

CMake: Remove hardcoded DIR_ROOT for alembic and MinGW

Do it for until precompiled libraries are there so we can allow
MinGW users to compile their own library and pass it via ROOT_DIR.

CMake: Use proper way to define debug/release libraries for alembic

Please do not spread platform+library specific code all over the CMake file,
we already have sections dedicated to that.

CMake: Do not force set root folder for Alembic

it is incorrect to set ROOT_DIR and then call find_package.

If something is expected to be in a given location use hardcoded
locations (for the precompiled libraries). Otherwise just use
find_package() and let users to set ROOT_DIT when it is required.
