Transform: Use new DEG query API to see what's being affected by a changing object

This avoids us from directly calling object update, and doing other type of
update flushing.

Prepares us to get rid of Object->recalc flags.

Depsgraph: Add query API to traverse all dependent IDs of the given ID

Depsgraph: Move iterator to own implementation file

Depsgraph: Cleanup, use enum value rather than a define

Depsgraph: Cleanup, naming

It makes more sense to stick to DEG_iterator_object order in name, since we can
have functions to iterate over different entities and we want all of them to
have common prefix.

UI: Minor changes to enable/disable multiframe options

Merge branch 'blender2.8' into greasepencil-object

UI: Show falloff only in sculpt mode

Changed the icon and other minor changes.

Redo Hero initialization curve hack code

There was a problem aving files. The curve was reset for each reload.

_gawain python module: Add methods "program_use_begin" and "program_use_end"

Required to updade uniforms

GP Modifiers: Split into multiple columns

The modifiers list was starting to get a bit long to just have all of
them in the same column.

Also fixed various typos and tweaked some tool tips.

UI Tweak: Move the multiedit toggle to the panel header (instead of being a separate button inside)

Added comment noting why the GreasePencilStrokeSculptPanel has an empty label

cleanup in smoke script

Cleanup: Fix comment

Temp Hack: Fix initialization code for Hero open movie files

The initialization code must be moved to next version to manage Hero files.

This section of code must be merged to the previous version as described in the comments.

Adjust UI to use new properties for falloff

WIP: Calculate falloff factor

RNA: Fix unreported: Some callbacks called when updating properties were incorrect

Removing OMP: legacy ccgsubsurf.

Performances gain is rather low this time, about 5% on average (in whole
affected functions).
