Having this in blenkernel caused bad level calls to bf_editors_anim,
causing tests that use 'blenkernel' to require almost all libraries.
(complicating gtest linking & causing large binaries).
The select option in the operator was never working because we were
trying to select an object considered unselectable (since it was hidden).

The poll function accepts hidden objects, so they are not stuck in pose
mode, but the operator itself expects a valid base, which we don't have.
When called from OBJECT_OT_mode_set() it will fallback to object mode.
It is the same that happens when in Edit Mesh mode with a hidden active
object and trying to change to Vertex Painting mode.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
This allows to update base flags to a proper state then object's restriction
flags are changed, without requiring to re-evaluate an entire tree of flags.
Some old unused flags are were removed by this change, and also disabling
menu items might not work the same as before. This is something we can bring
back if it's really needed (the way how flags are handled did change since
that interface code was done anyway, so code was looking weird anyway).

Now collection and objects can be either:
* Disabled for all the view layers.
* Hidden for a view layer but not necessarily for all others.
* Visible for a view layer but not necessarily for all others.
Regarding icons: Whatever we decide to use for the "Hidden for all view
layers" needs to be a toggle-like icon. Because when viewing "Scenes"
instead of "View Layer" in the outliner we should be able to edit the
collection "Hidden for all the view layers" as an on/off option.
The operators are accessible via a Visibility context menu or shortcuts:
* Ctrl + Click: Isolate collection (use shift to extend).
* Alt + Click: Disable collection.
* Shift + Click: Hide/Show collection and its children (objects and collections)
Things yet to be tackled:
* Object outliner context menu can also get a Visibility sub-menu.
* Get better icons for viewport enable/disable.
Note:
* When using emulate 3 button mouse alt+click is used for 2d panning.
In this case users have to use the operator from the menu.

Thanks to the reviewers and William Reynish and Julien Kasper in
particular for the feedback.
[re-committing]
We still control this in the viewport collections visibility menu. But
now we are actually changing the visibility of the collections, not of
the objects.
If a collection is indirectly invisible (because one of its parents are
invisible) we gray it out.
Also if you click directly in the collection names, it "isolates" the
collection by hiding all collections, and showing the direct parents and
all the children of the selected collection.
Development Note:
Right now I'm excluding the hidden collections from the depsgraph.
Thus the need for tagging relations to update.
If this proves to be too slow, we can change.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
The issue was caused by dependency graph resetting particles
when evaluating copy-on-write version of object. Solved by
only doing reset from dependency graph on user edits.
Other issue was caused by modifier itself trying to compare
topology and reset particles when number of vertices or faces
changed. This isn't reliable, since topology might change even
with same number of elements. But also, since copy-on-written
object initially always have those fields zero-ed the reset
was happening on every F12.
The latter issue is solved by moving reset from modifier stack
to places where we exit edit/paint modes which might be changing
topology.
There is still weird issue of particles generated at some
weird location after tapping tab twice, but this is not a new
issue in 2.8 branch and is to be looked separately.
There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
Right now we have a different behaviour whether users click on the name or on
the visibility eye.
When clicking on the eye, it is a toggle. When clicking in the name, you
are isolating this collection (unless you use shift).
As for the UI I tried using separator_spacer, but it was more work than
worth. A lot of sub panels, and LEFT/RIGHT alignment work just fine.
Note: I didn't change the shortcuts, I think this is a separate decision
to be made. I just want at the moment to have the H operator to mimic
the upcoming popover.
Personally if we are to keep the 1-10 shortcuts (and they do work) I
think we should skip the excluded collections altogether.
In fact we could have an option to hide them from the outliner too.
After clearing motion paths from objects, those objects needed to be
tagged for copy on write so that the copied data (i.e. viewport)
recieve the changes (i.e. removed paths)

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.
You can get more info here:
https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/https://code.blender.org/2018/07/grease-pencil-status-update/
This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
This prevents having to wrap each call to sbFree() in an if(ob->soft)
condition and assign ob->soft = NULL after calling.
Furthermore, passing `Object *` allows us to change freeing behaviour
depending on whether the object is an evaluated copy or an original (not
done in this commit yet).
This unifies two almost-identical functions at the expense of having to
add one single 'flag' value at one call.
This makes copy_softbody() aware of the source/dest objects, allowing it
to make a distinction between doing depsgraph evaluation copies and real
object copies. This will be used in an upcoming commit to ensure that
the pointcache is shared between CoW copies, similar to the current
approach for rigidbody simulation.
