Add several errno values for OpenBSD

[sourgrasses]

It looks like OpenBSD added several new errno values in 6.2, and they've already been added to libc, so this should allow any crates using those to build on OpenBSD.

Yikes, those are some long lines! While you're here, would you mind wrapping them to 80 columns?

[sourgrasses]

Ha, yeah, I was wondering about that and decided just to mimic the line above. Should I just rustfmt that whole file with a max width of 80? Those long lines come out like this:

#[cfg(any(target_os = "macos", target_os = "freebsd",
          target_os = "dragonfly", target_os = "ios",
          target_os = "openbsd", target_os = "netbsd"))]
EPROTO => "Protocol error",

It wraps some of the other cfg lines also in more or less the same style.

[asomers]

I'm not a fan of everything that rustfmt does. I wouldn't use it on parts of the file that you aren't changing.

[sourgrasses]

Sounds good. Should I go ahead and wrap those other really long lines I was mimicking?

[rennis250]

Is it mainly formatting that is holding this back? It would be helpful to have this available, because newer versions of some packages I depend on already check for EPROTO and won't compile on OpenBSD, forcing me to stay with older versions.

Thanks,

Sorry if I came off demanding. I was merely just inquiring. Thanks! :-)

I was actually just thinking of bumping this. It's blocking some wayland-related crates from compiling for me.

[rennis250]

Same! :)

Smithay/wayland-rs#259

[asomers]

Thanks for handling the formatting. Could you please do two more things?

1. Add a CHANGELOG entry that says something like "Added new errno constants from OpenBSD 6.2"
2. Squash the commits.

Timed out

Looks like Travis is super-slow today :'( . I'll try again late at night.

Merge conflict

[asomers]

Sorry, but merging master isn't the right way to resolve the merge conflict. You need to rebase instead.

[sourgrasses]

Yeahhh, whoops lol.
