parse-options: factor out register_abbrev() and struct parsed_option

Add a function, register_abbrev(), for storing the necessary details for
remembering an abbreviated and thus potentially ambiguous option.  Call
it instead of sharing the code using goto, to make the control flow more
explicit.

Conveniently collect these details in the new struct parsed_option to
reduce the number of necessary function arguments.
