DNA: support DNA type & name aliases

This allows us to rename struct & struct members in the source code
without changing the file format.

This is useful because the code becomes increasingly confusing when
names such as oops, ipo & dupli aren't used anywhere except DNA headers.

dna_rename_defs.h is used to define renaming operations.

The renaming it's self will be done separately.

DNA: warn about old versioning being incomplete

Also sync variable names w/ D4342

Fix T61512: Crash switching workspace with fullscreen area

In this case we simply create a new screen area that copies the currently
fullscreened area.

Note: At the moment there is no indicative in the non-main window that we are in
fullscreen. That happens because this information is part of the bar and we have
no topbar in this window.

Fix T61210: Crash/inconsistency when clicking on obdata in outliner

The problem
===========
For armature, if the active object was in pose mode and the newly
selected armature data (not the pose, but the edit armature) we would
get a crash.

For mesh objects, the issue would happen with the active object in object mode.
Then the new selected object would switch to edit mode, however the overall
mode would still be object mode, leading to unsynced mode across the objects.

The solution
============
Using shift to extend selection makes current selected (compatible)
objects to go to edit mode as well. Otherwise only the newly selected
object will switch to edit mode.

This also works if you are in edit mode for a curve, and click in a mesh icon.

This also changes the rules for multi-object editing (or rather, how we
put objects in and out of it). Now shirt is also taking into
consideration there. So if you simply click in another mesh object's
data, it will have only the newly selected object in edit mode.

To reproduce the old behaviour you need to use shift to include the
newly selected object in the multi-edit party.

Fix T61575: missing Cycles viewport updates when changing settings.

GP: Cleanup old ToDo

Fix T61572: Crash when copy/pasting nodes

was caused by rBc6e3a20ab60b, copied node was actually added to the
nodetree, resulting in an endless loop.

Add global control over disabling high-resolution smoke draw

Can be found in the viewport's simplify panel, allows to easily
disable high-res display for all the smokes in the scene.

Cleanup: More obvious name for the flag

Not sure what BIG is, it is HIGH RESOLUTION.

Cleanup: Naming, BKE prefix

Done for smoke functions.

Smoke modifier functions seems an oddballs here,
but probably also to be renamed.

Fix T61567: Object loose its rigid body data when moving to collection

At some I unified the "move to collection" with the remove from all collections
functionality. That meant that even when we were still to keep the object in one
of the collections we would clear its rigid body data.

Now why to even remove the rigidbody data when removing an object from all
collections? That mimics the 2.79 behaviour when we were to unlink an
object from a scene. I suspect it has to do with the rigid body data
being tied to the scene rigid body. Which is a strange design anyways
(add to the list?) since an object can be in more than one scene.

Cleanup: Line wrapping

Depsgraph: Speedup constraint source lookup

Is mainly used by drivers variables. The slow part was about
iterating over all pose channels to find the one which has a
given constraint.

Now we build a look up table, so this operation is way cheaper,

Brings down relations update time from 0.7sec to 0.4 with Spring
production file.

Depsgraph: Move RNA lookup to an own query class

Currently should have no functional changes, but allows to
implement runction optimizations more localized and easily.

Depsgraph: Correct logging of build time

Cleanup: Indentation

Bevel: remove workspace text message when exiting bevel.

The message with shortcuts was hanging around after bevel
exited.

Bevel: fix twist on bevel of cylinder with >= 200 sides.

This triggered an "almost parallel" case in setting the
offset meet points, which is OK but code needed improvement
put the meet point in a more accurate place.
This ia fix for part of the report T61214.

Depsgraph: Show build time on --debug-depsgraph-time

Previously was only shown on --debug-depsgraph-build which
had other unwanted noise.

Fix T61570: Monkey primitive fill color wrong

This was introduced by error in a previous commit.
