Both object level and camera datablock properties animation did not work with
copy on write enabled.
The root of the issue is going to the fact, that all interface elements are
referencing original datablock. For example, View3D has pointer to camera it's
using, and all areas which does access v3d->camera should in fact query for
the evaluated version of that camera, within the current context.
Annoying part of this change is that we now need to pass depsgraph in lots
of places. Which is rather annoying.
Alternative would be to cache evaluated camera in viewport itself, but then
it makes it annoying to keep things in sync.
Not sure if there is nicer solution here.

When using a tablet, detecting absolute motion only worked
when activating a tool with the tablet.
Pressing Enter to run a tool for e.g. would use relative motion.
Now store is_motion_absolute in the event,
set for new events based on the most recent motion events.
Makes the 3D view navigation widget easier to use: dragging anywhere
in the rotation region now rotates without having to avoid the XYZ axis
hotspots which only activate on a single click.
Logic for drag detection is complicated by manipulators reliance
on keeping the modal operator running.
Currently this is wrapped in an ifdef,
we may want to implement it differently later.
One or two are OK, but more make it rather unreadable, and future work
is likely to require more toggle specific behavior here. So switched to
bitflags, switching from short to int and using 16 upper bits for
'internal' ones defined in BLO_readfile.h, combined with 'public' ones
from user interaction, defined in DNA_space_types.h
Use dynamically generated message publish/subscribe
so buttons and manipulators update properly.
This resolves common glitches where manipulators weren't updating
as well as the UI when add-ons exposed properties which
hard coded listeners weren't checking for.
Python can also publish/scribe changes via `bpy.msgbus`.

This commit effectively reverts fix T45702 done in 067fe2719a.
Reasoning:
- Blender Internal is being replaced with Eevee, and will be removed entirely
rather soon.
- All render engines are planned to have own depsgraph, so such threading
conflicts should no longer be an issue.
- We don't want to spend time on porting workarounds for EOL things to a new
design. Less code -- faster the work :)
- If such notifications will end up needed for some other cases, we would
need to re-implement this a more proper depsgraph tagging/flushing and make
it to work with all copy-on-write datablocks and everything.
This is fully unreadable to have lots of boolean arguments scattered across the
whole argument list. What does `false, true, true` mean in terms of behavior?
Replace those with bitfield which has advantage of having more human readable
meaning.
This will later be used to show advanced operator properties separate from
basic (as in non-advanced) ones in the UI.
Tagging a single operator property in C should be done via
`WM_operatortype_prop_tag()`. It does additional checks for type safety
that `RNA_def_property_tags()` doesn't do.
To avoid having to tag each advanced property individually, multiple
ones can be tagged by wrapping them into
`WM_operatortype_props_advanced_bein()` and
`WM_operatortype_props_advanced_end()` calls. It's also possible to only
call `_begin()`, all properties added after this will get tagged then.
In most cases this last approach should be sufficient.
Example of Python usage:
`my_float = bpy.props.FloatProperty(name="Some Float", tags={'ADVANCED'})`
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

Checked in really old revisions, seems like this was never used. So
doesn't matter for compatibility either (tested opening files saved with
this in 2.49).
This is a final step of having proper ownership. Now selecting different
layers in the "top bar" will actually do what this is expected to do.
Surely, there are still things to be done under the hood, that will happen
in a less intrusive way.
