This change pulls the SEC options into a struct, which simplifies their handling across various modules (e.g. PA needs to forward on SEC options from the malloc_conf string, but it doesn't really need to know their names). While we're here, make some of the fixed constants configurable, and unify naming from the configuration options to the internals.
