  khash: implement begin/end via functions instead of macros
  
  Right now, the `git_*map_begin()` and `git_*map_end()` helpers are
  implemented via macros which simply redirect to `kh_begin` and `kh_end`.
  As these macros refer to members of the map structures, they make it
  impossible to move the khash include into the implementation files.
  
  Implement these helpers as real functions instead to further decouple
  the headers from implementations.
