* [C] Deprecate *_create() to avoid *_free() confusion
The behaviour of *_free() doesn't match *_create(), so the user should
avoid using them together. But they still need *_free() to clean up
library-allocated objects, so add a _library_owned flag to each struct
as an attempt to tell them apart. This isn't perfect though, because the
user may neglect to zero the field, but they would still see a warning
once in a while so it serves its purpose.
To prevent the new deprecation warnings (intended for the user) from
showing up during the library build itself, define a new family of
*_create_internal() functions, and turn *_create() into simple wrappers.
