    Remove redundant constraints from libraries, discovered by -fwarn-redundant-constraints
    
    This patch affects libraries, and requires a submodule update.
    
    Some other libraries, maintained by others, have redundant constraints,
    namely:
               containers
               haskeline
               transformers
               binary
    
    I have suppressed the redundant-constraint warnings by settings in
               validate-settings.mk
    (in this commit)
