Tweak API to support adding evaluated meshes to main database
One of the usecases is to create mesh from an object is a manner similar to
how Apply Modifiers does it, and have it in the bmain so it can be referenced
by other objects.
This usecase is something what went unnoticed in the previous API changes, so
here is a followup.
Summary of changes:
* bpy.meshes.new_from_object() behaves almost the same as before this change.
The difference now is that it now ensures all referenced data-blocks are
original (for example, materials referenced by the mesh).
* object.to_mesh() now creates free-standing Mesh data-block which is outside
of any bmain. The object owns it, which guarantees the memory never leaks.
It is possible to force free memory by calling object.to_mesh_clear().
