net/art: move child table pointers out of strideEntry
...
In preparation for a different refactor, but incidentally also saves
10-25% memory on overall table size in benchmarks.

net/art: fix slowPrefixTable bugs found by fuzzing
...
One is a straight "I forgot how to Go" bug, the others are semantic
mismatches with the main implementation around masking the prefixes
passed to insert/delete.

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.
