Eliminate some dead code that has persisted
Eliminate some dead code that has persisted

The code became dead with commit:
58ebe70c956b0e936006751153c8117dffcb6f7d.

The change to using Rust's unit test framework made some functions entirely
unnecessary and they got marked as dead. These two functions are still
unnecessary after approximately 18 months, might as well get rid of them.
