This PR adds a small utility constructor, io::Error::other, a shorthand for io::Error::new(io::ErrorKind::Other, err), something I find myself writing often.

For some concrete stats, a quick search on grep.app shows that more than half of the uses of io::Error::new use ErrorKind::Other:

Error::new\((?:std::)?(?:io::)?ErrorKind:: => 3,898 results
Error::new\((?:std::)?(?:io::)?ErrorKind::Other => 2,186 results

I wonder if we could just add a From impl for an arbitrary Error that does exactly this?

Thought of that, but it wouldn't work because io::Error already has a few From impls.

@ibraheemdev Oh, you're right; we probably can't support a general From for arbitrary Error impls because we already have specific impls that would conflict.

In that case, I think this is a fine shortcut to add and experiment with.
