Cycles: support baking normals plugged into BSDFs, averaged with closure weight.

Manipulator: helper API for drawing custom shapes

This exposes 2 methods for manipulators:
- new_custom_shape
- draw_custom_shape

This can be used for script authors to create and re-use shapes
without dealing with lower level API's.

PyAPI: add gpu.select (initial module)

This only exposes load_id, it's needed for Python manipulator drawing.

Manipulator: add read-only matrix_world

Code cleanup: remove copy of shader graph for bump, no longer needed.

Merge branch 'master' into blender2.8

Replace BLI_INLINE w/ Py_LOCAL_INLINE for Python

Recent inclusion caused build error with the BGE.

PyAPI: gpu.matrix.push_pop context manager

Avoid un-balanced push/pop usage (which can interfere with Blender's
internal state) using a context manager.

Fix bpy library load: invalid function signature

PyAPI: Add exceptions to stack push/pop

Raise exception when stack limits are reached.

PyAPI: use PyC_Long_As... for gawain

Avoids inline overflow checks.

Merge branch 'master' into blender2.8

PyAPI: Make use of PyC_LongAs... API

Avoids setting exceptions inline,
also use Matrix_ParseAny for bmesh.ops.

Some inline exceptions are kept because they show useful details.

PyAPI: Integer conversion functions

Python's C-API doesn't provide functions to get
int's at specific integer sizes.

Leaving the caller to check for overflow,
which ended up being ignored in practice.

Add API functions that convert int/uint 8/16/32/64, also bool.
Raising overflow exception for unsupported ranges.

PyAPI: avoid redundant PyLong_AsLong call

Assigning to an RNA array converted from Python to C twice.

PyAPI: correct int range checking

[windows/make.bat] add option to automatically download libs.

The thing that most often still goes wrong for new users building blender on windows is checking out the libraries, some skip over the wiki, some check out to the wrong folder, in an effort to reduce the time i spend on this, I added detection of svn and misisng libs to make.bat .

When the user has svn installed, and the libdir is missing he'll be asked if he wants to download them

if svn is not installed, or the user chooses 'no' the current error message is shown.

Fix T52452: OSL trace broken after shadow catcher recent changes.

We should only early out with any hit in BVH traversal if the only visibility
bits used are opaque shadow. Not when opaque shadow is one of multiple bits.

Cycles tests: pass Blender custom arguments from CYCLESTEST_ARGS.

This is useful for testing with different devices, split kernel, OSL,
impact of integrator settings, etc.

Code cleanup: move rng into path state.

Also pass by value and don't write back now that it is just a hash for seeding
and no longer an LCG state. Together this makes CUDA a tiny bit faster in my
tests, but mainly simplifies code.
