Cycles: Improve logging about motion blur a bit

Hair edit: Add operator to uniform length of selected hairs

Request by Andy, should help him a lot doing weird and wonderful hair styles.

A bit experimental yet, details of behavior might be changed after some real
usage feedback.

Correct error in recent snap-context commit

Edges currently don't use a BVH-tree,
but would still create and attempt to free the tree.

Fix T48176: Shrinkwrap crashes when multiple objects uses same target

Annoying bug caused by temp nature of looptri layer for CCGDM.

Fixed in a similar to CCG loops by using lock when allocating and
filling looptri arrays.

Real fix would be to make sure this array is allocated on object
evaluation using DAG's eval_flag, but that's more involved change
which we'll work on later.

Fix (unreported) possible freed memory usage when reloading a .blend file.

Operator would call `WM_file_read()` directly whith G.main->name as filepath, which
gets freed whith main during new reading of file... Now use a local copy instead.

Fix missing pose bone hash table in stub poses of action constraints.

This is a follow-up fix for rBa10b2fe. The Action constraint uses a hackish
stub object and pose, which doesn't have a hash table for fast lookups.
This doesn't seem to be a big issue with the old depsgraph, but in the new
depsgraph it creates a large number of cache misses and significant slowdown,
possibly because of additional threading and less simple bone loops.

Support multiple tangents for BI render & viewport

Normal Map node support for GLSL mode and the internal render (multiple tangents support).

The Normal Map node is a useful node which is present in the Cycles render.
It makes it possible to use normal mapping without additional material node in a node tree.
This patch implements Normal Map node for GLSL mode and the internal render.

Previously only the active UV layer was used to calculate tangents.

Fix T48211: Modifying an F-Curve modifier property is not updating the 3D window

Fix T48259: Vertex painting doesn't trigger refresh of cycles rendered viewport

Fix UI message typo.

Minor cleanup in object select code

- break when object in hit-buffer.
- don't measure distance to object centers that can't be projected.
- take pixelsize into account for distance pixel distance limit.

Fix T48203: Pose-Mode overrides Alt-RMB menu select

Now always use menu-select when using Alt-RMB

Cleanup: use const for outliner args

Also c99 edits for outliner_find_id

Outliner: "Show Active" support for active bone

Resolves T48229

UI messages fixes - no final point ;)

Cycles: Proper pack of leaves which are bigger than single float4

Fix for missing pose bone hash in the new dependency graph.

The hash table is used to look up bone poses, particularly during constraint
evaluation. Without this the default BLI_findstring method on a plain ListBase
is used, which is really slow for extensive rigs.

Fix T48202: Project paint hangs on UV's w/ sharp corners

Using 'shell-thickness' to offset UV's meant very sharp corners would offset far outside the image
causing project-paint to hang while collecting all pixels for each UV face.

Clamp the maximum offset to prevent this.

Cycles: Fix issues with stack allocator in MSVC

Couple of issues here:

- Was a bug in heap memory allocation when run out
of allowed stack memory.

- Debug MSVC was failing because it uses separate
allocator for some sort of internal proxy thing,
which seems to be unable to be using stack memory
because allocator is being created in non-persistent
stack location.

Cycles: Move vector re-allocation out of loops
