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.

RB_ROTATE_LEFT (and it symmetric twin) modify the rb-tree, adjusting
pointers so that what started as a proper tree ends up a proper
tree. When two consecutive rotations move the same node up the tree,
some of the pointers changed in the first rotation are immediately
changed again in the second - namely, the pointer from the rising node
to its new parent, and the pointer from that parent back to the rising
node. This change removes from RB_ROTATE macros the responsibility for
managing those two pointers, and leaves it to the code that calls for
rotations to fix up those pointers afterward. That drops a comparison
and a pair of assignments from every INSERT_COLOR or REMOVE_COLOR call
that ends in a double rotation.
A side-effect of this change is that the SWAP_CHILD macro must take as
a parameter a pointer to the node that is changing children, where it
is now computed from the old child. Since this macro is called in a
couple of places besides the RB_ROTATE macros, those calls are also
affected.

o Make struct domain hold a variable sized array of protosw pointers.
For most protocols these pointers are initialized statically.
Those domains that may have loadable protocols have spacers. IPv4
