m_option: remove preset mechanism

Was very complicated to use, and its uses have been removed in the
previous commits.

(While this feature sounded kind of useful, it could be rewritten in
a much simpler way, like storing presets as strings, and then using
the option parser to apply a preset. The removed code did some major
pointer juggling to handle raw values, which made it hard to use.)
