Multi-Objects: Select similar armature: SIMEDBONE_LENGTH

Also added epsilon into the mix.

Multi-Objects: Select similar armature initial commit

This includes all the modes that don't need multi-object support:

* SIMEDBONE_CHILDREN
* SIMEDBONE_CHILDREN_IMMEDIATE
* SIMEDBONE_SIBLINGS
* SIMEDBONE_GROUP
* SIMEDBONE_SHAPE

Unlike the mesh select similar operator, in this case we take
only the active bone in consideration, not all the selected ones.

I decided not to change that, and keep this 2.79 behaviour.
We could though if we want to.

Multi-Objects: ARMATURE_OT_select_hierarchy

Multi-Objects: ARMATURE_OT_select_less and ARMATURE_OT_select_more

Fix for POSE_OT_select_mirror

It was not taking duplicated objects into consideration, so the operator would
only work if you had an off number of objects with the same armature.

Multi-Objects: ARMATURE_OT_select_mirror

Fix (unreported) memleak with legacy IKsolver.

Looks like new depsgraph may initialize some IK trees, without ever
executing them (which also frees them with legacy IKSolver code)...

Addons: reactivate BVH and PLY format addons

Reviewers: brecht

Differential Revision: https://developer.blender.org/D3758

RNA ID: add accessors to original ID, and a boolean stating whether it is evaluated or original data-block.

Since RNA depagraph API mostly returns evaluated data, it is mandatory
to have access to original datablocks now...

Depsgraph/RNA: add warning that all data from object instances iterator are COW data.

It is crucial that scripts do not write, and even more importantly, do
not store any references to those. Otherwise, that?s a rather straight
path to crash.

UI: Fix error in shading popover

Fix weight drawing in Edit Mode by using the Weight Paint shader.

After rB3da46a8d8df2 the vertex color shader can't draw the raw
weight data produced by DRW_cache_mesh_surface_weights_get.

Keymap: disable alt-comma for origin only transform

This is quite an obscure option only useful in rare cases,
when enabled by accident it's confusing since single objects
can't be transformed.

Also, w/ 2.8x you don't see the option change in the header.

GP: Redo blur z-depth fix

The problem with previous fix was that only the original pixels were blurred, but the surrounding pixels no.

Gizmo: scale xyz axis to 1.0

The normal and xyz no longer overlap so can be the same size.

Correct extrude shortcut and description

To get the toolbar Key binding, the same operator needs to be
referenced from the tool.

GP: Cleanup shader

GP: Fix blur FX z-depth error

The z-depth must not be blurred, but use the original value.

Gizmo: option to switch between normal/xyz widgets

Cleanup: split extrude gizmo into own file
