Treat extent oracles and integrands as const arguments.

* include/extent-sampling.h (volume, volume_cone, volume_importance,
integral): Pass extent oracle and integrand as const arguments.
* src/extent-sampling.sc (volume, volume_cone, volume_importance,
integral, integral-per-direction): Likewise.
