Sequencer: Fix box select using incorrect rectangles for sequences

Reviewer: ISS

Differential Revision: https://developer.blender.org/D4968

Fix T58251: Cycles ignores linked meshes when rendering

The idea is to share a mesh data-block as a result across all objects
which are sharing same original mesh and have no effective modifiers.
This mesh is owned by an original copy-on-written version of object data.

Tricky part is to make sure it is only initialized once, and currently a
silly mutex lock is used. In practice it only locks if the mesh is not
already there.

As an extra bonus, even viewport memory is also lower after this change.

Keymap: Add back support for Set/Add/Subtract for box selecting in the Sequencer.

Merge remote-tracking branch 'origin/master' into soc-2019-npr

# Conflicts:

Clean up of lanpr_util stuff.

UI: use matching distance checks & define for dragging

Merge branch 'master' into greasepencil-object

Correct error in last commit

Keymap: add drag-only generic gizmo keymap

Allows gizmos clicks to fall through for gizmos which only drag,
currently unused.

Fix T65027: Snap 3D cursor on hidden faces doesn't work in Edit Mode.

I'm not very fond of adding new types of bvhtrees.
But this is probably the most efficient solution.

Merge branch 'master' into soc-2019-bevel-profiles

Progress on sampling the 2D coords along the curve's length. Sampling dysfunctional at the moment, debugging next. (Day 2)

Fix T65005: Missing "LINES_ADJ" and "TRIS_ADJ" in the GPU Python API.

Possible fix for T63685: macOS edit mode selection not working on second display

The idea is to force `glReadPixel` to run in the offscreen context.
And don't rely on any rendering context.

Cleanup: move gizmo keymap access into funcitons

Existing functions were written to match the setup_keymap callback.
Add versions that can be called with the window manager for convenience.

Merge branch 'master' into soc-2019-outliner

Outliner: Active element

Initial implementation for active elements. Currently works for select and extend selection

Cleanup: remove redundant sequencer under cursor check

Cleanup: correct private function naming

Use term 'glyph' instead of 'icon' since we already have event icons.
