Fix building on Windows and blenderplayer linking after weightpaint engine

Those problems were introduced on 20f95de6ba2d32dcff553251ff4de2efd5b76955.

Fix potential crash introduced by weightpaint engine when no active object

Cleanup: line length

Correct struct type (harmless)

Merge branch 'master' into 28

Fix error in node flag check

Weight painting with draw manager

This implements weight rendering with the draw manager, with all drawing
options (Shading, wire, face masking, vertex masking).

This is part of T51208

Merge branch 'master' into blender2.8

Correct over-alloc struct declaration

Draw Manager: Bring pose bones to the pose engine

Note: We should test if the armature is the "armature modifier" parent of the
object.

If any good samaritan feels like tackling this, the function to change
is: DRW_pose_mode_armature

Move pose-bone colors into draw_data

Also only allocate necessary number of bone segments.

"Fix" root cause of T51260 Forward compatibility crash fter adding new IDProp type.

We unfortunately cannot fix this for previous versions of Blender, but
at least the issue (Blender crashing on unknown IDProp types) should now
be addressed for future.

Simply reset unknown IDProp types to integer one, and reset its value to zero.

Render API/Cycles: Identify Render Passes by their name instead of a type flag

Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago.
However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images.
Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification.
Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes.

To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available.

To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers.
To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.

From a user perspective, nothing should change with this commit.

Error in last commit

Rename bPoseChannel's temp/cache pointer for DrawManager to draw_data.

More generic name, this remains a temp solution anyway, until we have
proper handling of temp data from 'magic DEG'! ;)

Fix bad scaling of BBone single-segment bones in new Armature drawing code.

Reported by @campbellbarton over irc, thanks.

Draw Manager: Use color-sets for solid pose-bones

Draw Manager: use pose bone theme and constraint colors

Cycles: Split kernel - sort shaders

Reduce thread divergence in kernel_shader_eval.

Rays are sorted in blocks of 2048 according to shader->id.

On R9 290 Classroom is ~30% faster, and Pabellon Barcelone is ~8% faster.

No sorting for CUDA split kernel.
