Fix restrict error in BLI_str_format_byte_unit

Don't use sprintf to append a string to it's self.

Also correct BLI_str_rstrip_float_zero's return value.

make.bat: Add support for building with ninja.

ninja is an alternative to msbuild designed for fast rebuilds. However there is no IDE support, builds only from the command line.

Comparison between msbuild and ninja for a full build, build time in seconds.

3D View: minor change to NDOF view orbit

This change is needed for 2.8, where the NULL check isn't a reliable way
of testing if dynamic offset is needed.

WM: check modal handlers for keymap lookups

Keep in sync with 2.8x

Cycles Denoising: Don't use atomics in the accumulation kernel on CPUs

The GPU kernel needs to use atomics for accumulation since all offsets are processed in
parallel, but on CPUs that's not the case, so we can disable them there for a considerable speedup.

Cycles: Cleanup: Remove duplicated atan2f definition for OpenCL

Turns out that atan2f was already defined for OpenCL.

make.bat/cleanup: removed stray echo in make.bat

make.bat: refactor make.bat

make.bat was starting to become hard to maintain, this refactors it into separate batch files for each stage of the process.

-Improved detection of msvc2013/2015
-Improved failure handling.
-Added check for working msbuild and C++ compiler
-Added verbose switch to ease trouble shooting.
-Added Check if svn/cmake/git are in the path before using them
-Display the build configuration before asking to download the libraries
-Offer an option to recover an interrupted checkout of the libraries.
-Automatically check out sub-modules in-case they are missing.

Fix T55034: Setting duplication group for multiple selected items only
affects one item

UI editing multiple selected items missed the case of PROP_POINTER

Add number and memory size formatting throughout the UI

This commit adds number formatting (thousands separator) to the baking panel. It also adds a new function to format memory sizes (KB/GB/etc) and applies it to the baking panel and scene stats. The new function is unit tested.

3D View: add pixelsize function w/o UI scale

[windows/make.bat] use a more reliable way of locating visual studio 2017.

The registry hack we were using wasn't very reliable, the recommended way to locating visual studio is using vswhere (15.2 and up), using it also allows to switch between the regular and pre-release versions.

UI: fix assert

Replace hard-coded button size check with UI_UNIT_X.

Caused icon-only buttons to have strings assigned based on UI-scale.

3D View: remove poll 3D view for copy/paste

These operators only need selected objects.

Cycles/Compositor: Add arctan2 operation to the Math node

The Math node currently has the normal atan() function, but for
actual angles this is fairly useless without additional nodes to handle the signs.

Since the node has two inputs anyways, it only makes sense to add an arctan2 option.

Cleanup: strip trailing space from interface files

Fix T55137: Compilation failing on non-x86-64 architectures

Some conversion helper functions were (most likely by accident) contained
inside an ifdef for SSE2 support, so on e.g. ARM they would be undefined
and therefore cause compilation to fail.
