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

Add a callback to allow custom node editors to draw their own

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.
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This is often invalid, outdated or misleading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.
This is needed because some RNA functions differentiate a NULL 'char *'
argument from an empty string.
Previously a NULL argument could be passed when the C definition
defined the default as NULL and the argument wasn't passed
which is a fairly hidden way of handling things.
Now strings use `PROP_NEVER_NULL` by default
which can be cleared for function arguments that allow None -> NULL.
- Logical use of fields since they define type information.
- Avoids using ordered-dict metaclass.
Properties using regular assignments will print a warning and load,
however the order is undefined.
