[[FIX]] Do not fail on valid configurations

When interpreting configuration values for strict-mode-related options,
do not modify user-specified values. Instead, preserve the values as
specified and encapsulate interpretation logic into stateless helper
methods on the `state` object.

This pattern allows JSHint to consistently issue warnings about invalid
configurations by ensuring that at any given time, all option values in
the `state` object reflect values explicitly specified by the user.

As noted in the in-line documentation, this approach required making
explicit certain sub-optimal behaviors which were previously implicit.
These concerns would best be addressed in a later patch, distinct from
the regression that prompted this changeset.
