Flesh out sysctl types further (follow-up of r290475)
Use the right intmax_t type instead of intptr_t in a few remaining places. Add support for CTLFLAG_TUN for the new fixed with types. Bruce will be upset that the new handlers silently truncate tuned quad-sized inputs, but so do all of the existing handlers. Add the new types to debug_dump_node, for whatever use that is. Bump FreeBSD_version again, for good measure. We are changing SYSCTL_HANDLER_ARGS and a member of struct sysctl_oid to intmax_t. Correct the sysctl typed NULL values for the fixed-width types.
