This is an amendment to 4bfc2c0311.
Add an autolimits compiler option. When true, *limited will be inferred from the presence of the *range attributes.
When false, models where limited is not specified, and range is will fail to compile.

- Mesh inertias can now be computed exactly for well-formed (no holes) non-convex meshes.
- To activate this feature, set `<compiler exactmeshinertia="true">` (defaults to `false`). This default may change in the future.
- Added `<geom shellinertia="true/false">` (defaults to `false`). When true, geom inertia is computed assuming all the mass is concentrated on the surface, and `density` is interpreted as surface density (mass/area). Currently only mesh geoms are supported.

Inertias of moving bodies are enforced to be greater mjMINVAL at model compilation, there is no need to enforce inertias at mesh load time. Tiny meshes could be static or part of a larger geom assembly, in which case their tiny inertia is not a problem.
Also, make error message for small masses/inertias more precise.
