Fix: Several pose select operators were not in fact working with COW

The following operators are fixed in this commit
* POSE_OT_select_linked
* POSE_OT_select_grouped
* POSE_OT_select_mirror

Cleanup: Some minor tweaks to code

Fix missing ID pointers expansion for ID itself in readfile code.

Was breaking static override chaining (static override of a linked
datablock that is already a static override in it original lib file).

Dummy mistake, thanks to @dfelinto for finding the bug.

Fix T55175: outliner "Show Active" not working.

added ghost stop triggers

stopped shards also will get their constraints disabled and still attached partners will be stopped too

Fix T55178: Cursor fails to restore on cancel

574c0fe38f332bd97c588029c0075ecba1fe19cd caused complications
restoring the cursor.

Use WM_cursor_modal_set/restore which is intended for operator use,
calling ED_region_cursor_set after an operator runs isn't reliable.

Replace per-vertex sampling weights with per-loop for more control (e.g. face maps).

Cleanup: unused variable

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'hair_guides' into hair_guides_grooming

Fix indexing for hair guide curve drawing.

Depsgraph: tag depsgraph for copy-on-write flush when RNA changes

Fixes bug with changes to properties not being flushed to the COW data.
It fixes T55144.

This is the part of rBb4b745b72064 that is required although slow.
Which was partially addressed but the rest of the commit, which in
turn broke things. So for now let's get RNA to flush slow cow, and
deal with the consequences.

Fix T55171: crash with undo and linked collections.

Collections created in library file versioning need to be set as coming
from the library, otherwise they get freed on undo.

Fix Lamps, Empties, Cameras and Speakers not using theme colors

Merge branch 'hair_guides' into hair_guides_grooming

Fix hair cache update flag combination, have to include dependencies regardless of cache state.

Merge branch 'hair_guides' into hair_guides_grooming

Only pass export cache to lower level draw functions, do export on higher levels.

Draw mode for hair guide curves.

Handle hair cache dependencies internally during invalidation to make partial updates more flexible.
