 {{{#!CommitTicketReference repository="git"
 revision="ae7249900558365d48a7c5fe5ed34463becd8382"
 Fix ST_Length and ST_Perimeter for geography collections, closes #6076

 ST_Length(geography) on collections now only sums linear components,
 and ST_Perimeter(geography) now only sums areal components. Added
 lwgeom_perimeter_spheroid to support the separation of logic.
 Preserve legacy behaviour in ST_LengthSpheroid.
