Side-reported in T70505.
Code did not ensure deleted object was removed from the RBW constraints
collection, leading to some invalid status (object in constraints
collection but without relevant contraints data).
Also fixed another issue - code deleting RBW objects would try to remove
any constraint one using it as target, in a very bad and broken way,
since you cannot iterate over objects of a collection while removing
some... Now instead just NULLify relevant pointers... I hope it works,
otherwise we'll have to take a different approach.
Needless to stress again how weak the whole RBW code is in general, and
regarding same object being used by RBW in more than one scene in particular,
that is known broken situation anyway.

Seems to be an issue of not correctly freeing the PTCacheEdit (see
T68645 for details), after discussion with sergey we went with the quick
and dirty fix to free the path cache early for now. Other solution of
freeing it in 'psys_cache_paths' for the non-evaluated psys [which would
also fix the particle delete, then undo crash from T69000] needs more
deep investigation and, possibly, reconsideration.

Caused by rB914427afd512.
Since above commit 'pe_get_current' checks for an active depsgraph. This
caused the skipping of handling
`PT_CACHE_EDIT_UPDATE_PARTICLE_FROM_EVAL`for everything calling
`PE_get_current` (this passes a NULL depsgraph as opposed to
`PE_create_current`). So we now pass a depsgraph here as well...
Note there are two RNA cases where we pass NULL, namely
- rna_ParticleEdit_editable_get
- rna_ParticleEdit_hair_get
I guess these should be fine though (no functional change to current
master)

If fade_time is used, particles would be flagged PEK_HIDE (depending on
time settings), but since this is not respected in drawing in 2.8 yet
the user would have no indication of them keys being hidden.
Also doing this for hair doesnt make much sense anyways...

Even though hidden/faded keys are not supported in drawing in 2.8 yet,
the selection tools should not be able to select non-visible keys.

Particularly noticeable when vertex painting with a subsurf modifier.
In some cases every sculpt or paint stroke step would evaluate the dependency
graph. This should only happen for redraws. Now more selectively choose if the
dependency graph should be evaluated to initialize the view context. Doing it
in the view context evaluation is somewhat hidden, now it's more explicit.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.

Mesh can not be requested from original object, and it can not be
copied into evaluated modifier because there is no such a thing yet.
It can not be done this way now, because getting evaluated object
will force it to re-calculate, which kind of defeats idea of this
code to preserve un-baked particles.
Make sure particle system edit never points to a modifier or particle system
which becomes inactive.
This is needed because copy-on-write will change pointers of them and those
pointers are supposed to be restored from particle system evaluation. But
since the particle system is disabled it never updates pointers.

Previously settings were removed, now add to the rigid body world automatically
even if it's a bit ill defined, since this is confusing for users.
Fundamentally the concept of a rigid body world collection could be revised, and
left only as an optional thing.
This reverts commit 36faf739a7.
Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.
Since this change was not sufficient to get original report fixed
is easier to simply revert for now.

Allows it to be preserved during copy-on-write update when on-geometry
related update is needed.

When the modifier uses vertex groups, the set of the bones it actually
needs is precisely defined by the set of the group names. If envelopes
are enabled, this refinement is not available, because any bone can
potentially be used.
This can be used in the dependency graph construction to allow objects
deformed by a part of the armature to be used in constraints on other
bones, e.g. for placing cartoon-style face elements on top of the body
mesh via Shrinkwrap constraints.
Since the list of vertex group names is now used as an input by
the dependency graph, adding/removing/renaming groups should now
be triggering a graph rebuild.

Modifier previews should be implemented by a more generic system.
The current system is already a hack and needed a lot of work
to get it working again in 2.80 and even so that would be replaced by
another system in the near future.
For Vertex Colors we have a work around in place by using Workbench
Vertex Colors. For Vertex Weights we loose the previewing. Not sure
targetting weight is working (even for 279).
