Avoid creating new Python instances
every time a scene, object, mesh .. etc are accessed.
Also resolves crashes T28724, T53530
although it's only valid for ID types, not modifiers vertices etc.
Back-ported from blender2.8 branch.
Adds support for defining a number of tags as part of the rna-struct
definition, which its properties can set similar to property-flags.
BPY supports setting these tags when defining custom properties too.
* To define tags for a struct (which its properties can use then), define the tags in an `EnumPropertyItem` array, and assign them to the struct using `RNA_def_struct_property_tags(...)`.
* To set tags for an RNA-property in C, use the new `RNA_def_property_tags(...)`.
* To set tags for an RNA-property in Python, use the newly added tags parameter. E.g. `bpy.props.FloatProperty(name="Some Float", tags={'SOME_TAG', 'ANOTHER_TAG'})`.
It seems that `typestr` does not always define the final size of the element. And it varies by operating system.
Then use the `typestr` only to know the itemtype is `float` type or not.
It has been deprecated since at least macOS 10.9 and fully removed in 10.12.
I am unsure if we should remove it only in 2.8. But you cannot build blender with it supported when using a modern xcode version anyway so I would tend towards just removing it also for 2.79 if that ever happens.

- Use indices instead of character args.
- Use numbered macros instead of variadic args.
Parsing using rtags used over 11gb of memory. While this should be
resolved upstream (report as #1053), the extra complexity didn't give
any real advantage.
Operators and their properties are two different types
Previously both operators and their properties are added
causing C operators to access the properties, Python the classes.
Favor consistency in this case so only Python classes are added.
