ipfilter: Avoid negative array indicies
Array indices must always be posive. We avoid this by making each index
unsigned. This mitigates out-of-bounds reads and writes.

capsicum-tests: remove Linux support
Now that this project is part of freebsd-src, it no longer needs to be
portable. Remove Linux-only tests, cross-os compatibility code, and
compatibility with older FreeBSD versions. Leave in place some
originally Linux-only tests that could now be ported to FreeBSD, like the
pipe2 tests.

syslogd: Improve handling of configuration errors
Make parse_selector() print a warning to stderr and continue parsing the
config if it encounters an invalid facility or priority. Note that
because the parsing is done from a casper service, there isn't a good
mechanism to log errors; the warnings are visible only when syslogd is
started in debug mode.

pdrfork(2): do require RFPROCDESC | RFPROC
when RFSPAWN is not specified, as stated in the man page.
rfork(2) cannot modify non-curproc, which is why RFPROC is required,
the syscall cannot act on arbitrary process descriptor.
If RFPROCDESC is not specified, the syscall does not make sense,
use rfork(2).

sys/netinet6: Use atomic(9) for dad_failures counter
Replace counter(9) usage with more lightweight atomic(9) in the
code handling RFC 7217 SLAAC address generation.
Also, use `u_int` types with this. Leaving `dad_failures` local to
`in6_get_stableifid()` as a `uint64_t` to avoid changing the generated
addresses from previous code; this also gives some headroom for
future changes.
While here, moved some `#include` lines to adhere to style(9).

sys/netinet6: Fix ABI breakage introduced with RFC 7217 support
commit 31ec8b6407fdd5a87d70265762457c67ce618283 added a `dad_failures`
variable to `struct nd_ifinfo`, which broke the netowrking ABI.
This commit fixes it by moving such variable to `struct in6_ifextra`
which is not a public interface, while `struct nd_ifinfo` is back
in its original state.
Thanks to kib, markj and glebious for their help and suggestions
in solving this problem.

sys/netinet6: Implement RFC 7217
Implement RFC 7217 (A Method for Generating Semantically Opaque
Interface Identifiers with IPv6 Stateless Address Autoconfiguration
(SLAAC)) in our IPv6 stack.
A new ifconfig `stableaddr` flag is added to enable the feature on
interfaces, which defaults to on or off for new interfaces based
on the sysctl `net.inet6.ip6.use_stableaddr` (off by default, so
this commit causes no change in behavior with default settings).
The algorithm follows the RFC in its logic, using SHA256-HMAC as
the algorithm to derive addresses so as to provide code that can
be leveraged by future implentations of RFC 8981, leveraging the
`hostuuid` as the secret.
The source of the hostidentifier can be configured using the sysctl
`net.inet6.ip6.stableaddr_netifsource`, while the number of retries
generating a new address in case of collision can be configured
