Zach BrownandZach Brown	495358996c	scoutfs: fix older kc readdir emit ... When we added the kernelcompat layer around the old and new readdir interfaces there was some confusion in the old readdir interface filldir arguments. We were passing in our scoutfs dent item struct pointer instead of the filldir callback buf pointer. This prevented readdir from working in older kernels because filldir would immediately see a corrupt buf and return an error. This renames the emit compat macro arguments to make them consistent with the other calls and readdir now provides the correct pointer to the emit wrapper.

Zach BrownandZach Brown	ddd1a4ef5a	scoutfs: support newer ->iterate readdir ... The modern upstream kernel has a ->iterate() readdir file_operattions method which takes a context and calls dir_emit(). We add some kernelcompat helpers to juggle the various function definitions, types, and arguments to support both the old ->readdir(filldir) and the new ->iterate(ctx) interfaces.
