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.
