CMake: Add additional search path for OpenSubdiv

This patch will match where install_deps puts OpenSubdiv.

install_deps: Cleanup, delete trailing whitespace

Based on patch D1644 by Jeffrey Hoover

CMake: De-duplicate checks around unordered maps and shared pointer

Previously several areas were calling TEST_SHARED_PTR_SUPPORT and
TEST_UNORDERED_MAP_SUPPORT which isn't that bad on it's own but
was causing some quite verbose output with same information line
printed multiple times. additionally, what's more worse, define flags
for Ceres were duplicated in main CMakeLists and Ceres's CMakeLists.

Now we've got a single place where checks for those classes are
happening and other areas are simply checking for variables set by
those check macros, keeping CMake output clean and nice.

Cycles: Add option to directly link against CUDA libraries

The main purpose of such linking is to make Blender compatible with
NVidia's debuggers and profilers which are doing some LD_PRELOAD
magic to intercept some function calls. Such magic conflicts with
our CUDA wrangler magic and causes segmentation faults.

The option is disabled by default, so there's no affect on any of
artists.

In order to make Blender linked directly against CUDA library use
the WITH_CUDA_DYNLOAD CMake option (it's marked as advanced).

Weight Painting: Respect locks w/ auto-normalize

Fix weight paint normalizing w/ locked groups

Reported as part of T47123

Checks for locked groups assumed auto-normalize
and would distribute wight between groups even with auto-normalize disabled.

Fix incorrect weight normalize w/ locks

D1712 by @angavrilov

Correct NULL checks in recent weight-paint fix

Cleanup: use const qualifier in makesdna

Cleanup: use BM_mesh_* prefix for BMesh functions

UI: show error when pasting fails

Fix T47170: Sculpt w/ constructive modifier crash

Regression in 4d33c37c9

Only copy normal arrays from sculpt to the DerivedMesh when the mesh is deformed.

Constructive modifiers calculate their own normals.

Add object & pose-mode select more/less menus

Exposes object parent/child select, which wasn't in any menus.

Add object mode select more/less

Simple operator that selects using parent/child links.

BI "Real Sky" option works incorrectly for environment texture.

How to check?

1) Set Rendered mode for 3d View
2) Set "Blend Sky" and "Real Sky" flags for world.
Rotate view you will see right color blending from Horizon to Zenith color.
3) Add environment texture
Rotate view and you will see incorrect texture mapping that is not correspond to color blending that was observed in previous step.

So I conclude that this is a bug.

This issue must be solved before the patch D1414 because BI behavior is the viewport target.

Use const qualifier in do_sky_tex

Will be needed for D1729.

Remove outdated assert

Polyfill2d: improve sweep clipping logic

Now only reverse the fill direction when reaching a non-concave corner.
Gives ~4x speedup here in tests with complex ngon.

Final OMP -> BLI_task commit for sculpt code.

BMesh: select next can now step over existing selection
