  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.
