-- Given a placetype, split the placetype into one or more potential "splits", each consisting of
-- a three-element list {PREV_QUALIFIERS, THIS_QUALIFIER, BARE_PLACETYPE}, i.e.
-- (a) the concatenation of zero or more previously-recognized qualifiers on the left, normally
--     canonicalized (if there are zero such qualifiers, the value will be nil);
-- (b) a single recognized qualifier, normally canonicalized (if there is no qualifier, the value will be nil);
-- (c) the "bare placetype" on the right.
-- Splitting between the qualifier in (b) and the bare placetype in (c) happens at each space character, proceeding from
-- left to right, and stops if a qualifier isn't recognized. All placetypes are canonicalized by checking for aliases
-- in placetype_aliases[], but no other checks are made as to whether the bare placetype is recognized. Canonicalization
-- of qualifiers does not happen if NO_CANON_QUALIFIERS is specified.
--
-- For example, given the placetype "small beachside unincorporated community", the return value will be
-- {
--   {nil, nil, "small beachside unincorporated community"},
--   {nil, "small", "beachside unincorporated community"},
--   {"small", "[[beachfront]]", "unincorporated community"},
--   {"small [[beachfront]]", "[[unincorporated]]", "community"},
-- }
-- Here, "beachside" is canonicalized to "[[beachfront]]" and "unincorporated" is canonicalized
-- to "[[unincorporated]]", in both cases according to the entry in placetype_qualifiers.
--
-- On the other hand, if given "small former haunted community", the return value will be
-- {
--   {nil, nil, "small former haunted community"},
--   {nil, "small", "former haunted community"},
--   {"small", "former", "haunted community"},
-- }
-- because "small" and "former" but not "haunted" are recognized as qualifiers.
--
-- Finally, if given "former adr", the return value will be
-- {
--   {nil, nil, "former adr"},
--   {nil, "former", "administrative region"},
-- }
-- because "adr" is a recognized placetype alias for "administrative region".
