Remove axis transform defines and use existing enums

Clean up: comments, minor refactor.

Use `const char *set_name` instead of `void get_name` which was meant
to copy the buffer originally but then was neglected.

Don't expose `_export_mesh_eval` just for ensuring normals, moved it to
another function.

Use conventional destructor function names.

Upper case enums.

Merge branch 'master' into greasepencil-object

Support multiple materials in the same object.

Design has slightly changed:
The line with `usemtl` has moved just before a face element is
being written. So whenever a face with a new material is encountered,
it can be labelled.

Appending to the MTL file is still at the same place, writing once every
object.
