Convert api functions to autoload-style

Rename the speeddating API functions to use autoload style in
preparation for porting to autoload. Other functions are kept as
script-level functions since they aren't accessed outside of speeddating
(and don't need to be loaded on-demand -- only after the API is loaded).
