net/art: make each strideTable track the IP prefix it represents
This is a prerequisite for path compression, so that insert/delete can determine when compression occurred. Updates #7781 Signed-off-by: David Anderson <danderson@tailscale.com> |

net/art: disable the IPv6 100k routes benchmark.
At the current unoptimized memory utilization of the various data structures, 100k IPv6 routes consumes in the ballpark of 3-4GiB, which risks OOMing our 386 test machine. Until we have the optimizations to (drastically) reduce that consumption, skip the test that bloats too much for 32-bit machines. Signed-off-by: David Anderson <danderson@tailscale.com> |

net/art: implement the stride table building block of ART
A stride table is an 8-bit routing table implemented as an array binary tree, with a special tree updating function (allot) that enables lightning fast address lookups and reasonably fast insertion and deletion. Insertion, deletion and lookup are all allocation-free.
