This copies over some files from the main repo to make the

No clue whether it actually works or not, though. We don't have
builders anymore for this port.

But once this compiles, we'll at least be able to use constants from
the x/sys/unix package from x/net without regressing x/net's support
for openbsd/arm. (If anybody uses openbsd/arm)

Capsicum support was added by https://golang.org/cl/47290, but only for
amd64. This broke the freebsd/386 build which was subsequently fixed by
http://golang.org/cl/51270. However, even with this fix the tests still
fail to build due to the missing Capsicum functions and types.

Fix the build/test on freebsd/386 for real by re-running mkall.sh on
FreeBSD 11.1-RELEASE (inside VirtualBox) to get all the Capsicum
functions and types.

Some zerrors constants were removed or converted to enums in the FreeBSD
headers. Manually move them to a dedicated file. Do the same for amd64,
where these constants were removed by accident in
https://golang.org/cl/47290.

the only valid value for the flags parameter and EOPNOTSUPP should be
returned in case changing the mode of a symbolic link is not supported
by the underlying system.  EINVAL should be returned for any other value
of the flags parameter.
