Tweak for previous commit: Just group all bone properties under the bone name

After more testing, I realised that bendy bone properties should also be grouped,
but probably all other per-bone settings too. Now, just group all of them, since
it's easier for everyone this way.

Modifiers: Bring back custom data referencing logic

Brings dependency graph evaluation time to similar time than 2.79
for file reported in T55228.

Modifiers: Make input of modifier stack referencing copied CD layers

The idea is to allow modifier stack to reference custom data layers
from copied version of mesh datablock.

Modifiers: Restore duplication of referenced layers

Was no reason to remove those calls, it was always a plan to bring
referenced layers back eventually.

Merge branch 'blender2.8' into greasepencil-object

Rework in modifers apply parameters

Instead to pass the Context variable that it was used to get bmain pointer,now bmain is passed as parameter to reduce data and avoid any use of Context.

Insert Keyframe: Change default behaviour for how F-Curves get grouped

For many years, animators have been complaining about how keyframing a (transform)
property directly would leave them ungrouped, while keyframing them using a Keying Set
would put them into a group based on the name of the keyingset.

This commit attempts to improve (unify + make consistent) the default behaviour:
* All object transforms now get added to an "Object Transforms" group,
regardless of whether they were added individually via buttons or keyingset
* All bone transforms now get added to a group corresponding to the name of the bone
instead of only the ones added via keyingset

Cleanup: Reuse existing scene pointer

Merge branch 'greasepencil-object' of git.blender.org:blender into greasepencil-object

Remove context parameter

This parameter is removed because Context must be avoided.

Fix missing movieclip ID type in allowed ones for Outliner...

Cleanup: shadowed var

Modify mode set routine to enable grease pencil modes

Now, when you press the numeric key to change mode, if the object is grease pencil, the grease pencil mode is enabled.

Object Modes: don't de-select others when activating

Remove keymap for changing brush using numbers

This brush selection wil be replaced with spacebar and a menu.

Fix render info not working with overlap regions

Object Modes: stay in object mode when setting active

When activating an object from the 3D view or outliner,
keep the newly selected object in object mode.
