FreeBSD: Organize sysctls
FreeBSD had a few platform-specific ARC tunables in the wrong place: - Move FreeBSD-specifc ARC tunables into the same vfs.zfs.arc node as the rest of the ARC tunables. - Move the handlers from arc_os.c to sysctl_os.c and add compat sysctls for the legacy names. While here, some additional clean up: - Most handlers are specific to a particular variable and don't need a pointer passed through the args. - Group blocks of related variables, handlers, and sysctl declarations into logical sections. - Match variable types for temporaries in handlers with the type of the global variable. - Remove leftover comments. Reviewed-by: Alexander Motin <mav@FreeBSD.org> Signed-off-by: Ryan Moeller <ryan@iXsystems.com> Closes #13756
