Fix some C function documentation in the test framework
The primary goal of this commit is to fix various comments where
`clang -Wdocumentation` identified a discrepancy between the actual
function parameters and the documented parameters. The discrepancies
were due to copypasta, formatting issues or documentation that had
diverged from the implementation.
