In case the property is a RNA pointer, `RNA_path_resolve()` will try to
resolve it and return that pointer, instead of returning expected
container... That is a bad inconsistency in the rNA path API, but no
proper way to solve it for now...
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.

That file was getting out of control, now comparison/override RNA code is
in `rna_access_compare_override.c`. 1K lines of code for now, but that
area is likely to grow more in the future...
Note that we can probably split more out of `rna_access.c`, but for now
that will do.
We cannot use local/reference here, that is very confusing, since at
that stage current local is kind of src of data for the future local ID,
that is currently a mere copy of the linked data... ;)
So we are much better with src/dst names here.
We were storing the 'item' part in the RNA path of the override op
itself, which will not work with IDs because overriding local one might
not have the same name as the linked one (when some local ID with same
name already exists).
Now we are properly handling this using the expected actual override
operation, which stores necessary data (names or indices) from both
local and linked data.
To fully support storing colors as a custom property, it is necessary
to allow switching the property UI to the standard color picker button.
That means in effect supporting custom property subtype values.
Change RNA_property_subtype to look for a 'subtype' string field
in _RNA_UI and parse it as an enum value. To minimize performance
impact, only do it if the property is an array; also, don't use
the custom subtype during RNA path parsing.
On the python side, allow setting some most useful seeming values
from the custom property settings editor.
Also, since some color picker code seems to run into a risk of
buffer overruns if the array size is wrong, check the size in
the UI layout code to be safe.

In some rare cases it is convenient to store a short array value
as a custom property, e.g. a vector or color. For example, it may
be helpful when importing/exporting certain formats that support
custom or nonstandard attributes on objects.
The custom property storage already can handle arrays in order to
support properties defined via python. The only thing missing is
UI support (and some bugs), and this patch fixes that:
- Allow editing short array properties via Custom Properties panel.
- Fix a UI layout sizing bug triggered by the previous item.
- Fix a dependency graph bug with drivers using such properties.
- Make RNA_*_get_default_array code robust in case of size mismatch.
- Support custom default values for array properties, allowing
both an array and a scalar value.

Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
The goal is to prevent assignment of temporary or evaluated meshes
to objects from the main database.
Majority of the change is actually related on passing reports around.
On a positive side there are more error prints which can become more
visible to scripters.
There are still possible further improvements in the related areas.
For example, disable user counting for evaluated ID datablocks when
assignment happens. But can also happen later on as a separate
improvement.

This also makes `IDP_CopyProperty` the "opposite"
of `IDP_FreeProperty`, which is what I'd expect.
Two refactoring steps:
* rename IDP_FreeProperty to IDP_FreePropertyContent
* new IDP_FreeProperty function that actually frees the property

NLA requires a usable default value for all properties that
are to be animated via it, without any exceptions. This is
the real cause of T36496: using the default of 0 for a scale
related custom property obviously doesn't work.
Thus, to really fix this it is necessary to support configurable
default values for custom properties, which are very frequently
used in rigs for auxiliary settings. For common use it is enough
to support this for scalar float and integer properties.
The default can be set via the custom property configuration
popup, or a right click menu option. In addition, to help in
updating old rigs, an operator that saves current values as
defaults for all object and bone properties is added.

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.
Fixes T58632: Particle don't update rotation settings
The python getters for the array already allowed that, but not the
actual C RNA access functions. This is inconsistent, so implement
the fallback in all cases. Now if by default the property should
contain the same value in all positions, it is not necessary to
actually use an array.

No need to tag object for time update, with new dependency graph
this forces animation to be re-evaluated, which is not something
we want in this instance.
Same patch/solution Philipp Oeser came to as well.
That feature will not be ready (or at least, not tested enough) to be
officially part of 2.80 beta. So we disable it by default, hidding it
behind a startup option (`--enable-static-override`), and a python
app var (`bpy.app.use_static_override`).
That way, people who really want to play with it can do it easily, while
not exposing/enabling non-production-ready feature by default.
Note that underlying override code remains active, i.e. files we do have
overridden data-blocks will be loaded correctly according to static override.
This was re-enabled because it made copy-on-write bugs hard to
track down.
Since copy-on-write implementation has been simplified
this isn't a problem anymore.
