Alan Somers d3f96f6610 Fix O(n^2) behavior in sysctl ... Sysctl OIDs were internally stored in linked lists, triggering O(n^2) behavior when userland iterates over many of them. The slowdown is noticeable for MIBs that have > 100 children (for example, vm.uma). But it's unignorable for kstat.zfs when a pool has > 1000 datasets. Convert the linked lists into RB trees. This produces a ~25x speedup for listing kstat.zfs with 4100 datasets, and no measurable penalty for small dataset counts. Bump __FreeBSD_version for the KPI change.
