IPv6 on, forgetest dual-stack, the release rootfs sheds 22 MB

Browse Source 
The distro keeps its ipv6 feature (busybox networking and ifupdown
inet6, openssh, ntp and rsyslog follow); forgetest binds "::" by
default, one dual-stack socket that still serves IPv4. The release
image drops nano (with it file and the libmagic database, 8.7 MB; the
dev image keeps nano), the udev hardware database (7.7 MB of USB and
PCI identities for buses the board lacks, via BAD_RECOMMENDATIONS) and
urllib3's pyOpenSSL/cryptography recommendation (6 MB; nothing imports
them, TLS goes through the standard library). BRINGUP item 21 records
the round and the bench checks it owes; item 16 gets its re-measure
plan on the UP kernel with the performance governor.

Coverage: image.* covers the rootfs composition and the distro conf
(platform); forgetest's own suite covers the server.
