We then use this new struct type to fix problematic middle-flex-array declarations in multiple composite structs, as well as to update the type of some variables in various functions. Changes in v2: - Update changelog text in patch 2/2 to better reflect the changes made. (Jakub) - Adjust variable declarations to follow the reverse xmas tree convention.
