  khash: move khash include into implementation files
  
  The current map implementations directly include the "khash.h" headers
  into their own headers to make available a set of static functions,
  defines et cetera. Besides leaking the complete khash namespace into
  files wherever khashes are used, this also triggers Clang's
  -Wunused-function warnings when some of the static functions are not
  being used at all.
  
  Fix the issue by moving the includes into the respective map
  implementation files. Add forward declares for all the map types to make
  them known.
