loopback: improve checksum offloading
* Allow disabling IFCAP_RXCSUM_IPV6 or IFCAP_TXCSUM_IPV6.
* Do not pretend the checksum is correct by setting the LO_CSUM_SET
flags if IFCAP_RXCSUM_IPV6 or IFCAP_RXCSUM is enabled. Instead,
remove the LO_CSUM_SET flags (in case they have been set somehow)
if IFCAP_RXCSUM_IPV6 or IFCAP_RXCSUM is disabled.
* Do not unset the transmit checksum offload flags LO_CSUM_FEATURES or
LO_CSUM_FEATURES6 since they now have a meaning for the receive path.

virtio_pci_modern: Remove endianness conversion for config space
The bus_* functions already handle converting from PCI endianness
(i.e. little-endian) to native endianness when accessing the config
space (see ofw_pcib_bus_get_bus_tag), so converting again with
virtio_htogX/virtio_gtohX undoes any byte-swapping and breaks
big-endian systems. They should only be used for operating on shared
memory.
Note part of this reverts commit fb53b42e36a9 ("virtio-modern: fix PCI
common read/write functions on big endian targets").

adduser: Normalize supplemental groups
Rather than insist on a space-separated list, normalize the input so

rc: Improve load_kld
* Centralize the usage message.
* Document and enforce that -e and -m are mutually exclusive; previously,
speficying both would result in only -e being applied.
* If -e was not specified, and -m was not specified or did not match,
fall back to `kldstat -n file` which will always work for modules that
aren't built into the kernel.
This means the kld and ntpd scripts can now rely on load_kld to dtrt.

rc: Fix improper use of load_kld
Fix scripts that needlessly used -e when the simpler -m would work, or
that used -m when the module and file name are the same, or, in one
particularly egregious case, used -m with the wrong name when using
nothing at all would have worked just fine.

rc: Make devmatch use load_kld
The default behavior of load_kld is now robust enough for devmatch.
Switching means settings from /etc/sysctl.kld.d are now properly applied
when the corresponding modules are loaded by devmatch.
While here, reduce the amount of output produced by devmatch from one
line per module to a single line.
