  khash: implement map-specific foreach macros
  
  The current foreach map macros simply redirect to the type-indifferent
  `kh_foreach` macro. As this type-indifferent macro directly accesses the
  structures, the current implementation makes it impossible to make the
  stuctures private to the implementation only. And making them private is
  required to move out the khash include into the implementations to
  decrease the namespace leak.
