Consolidated list processing to a single loop in mdoc_validate.c. This

relieves having to repeat running over the argument list in
mdoc_action.c and mdoc_validate.c.

Default to LIST_item for type-less lists (groff technically doesn't do
this: it just ignores the `It' lines altogether).

Make MANDOC_LISTTYPE be a recoverable error.
