Read available data from file descriptors without blocking

Useful for nonblocking reads from sockets, named pipes, and child stdout/stderr

Example

use std::io::Read;
use std::process::{Command, Stdio};
use std::time::Duration;
use nonblock::NonBlockingReader;

let mut child = Command::new("some-executable")
                        .stdout(Stdio::piped())
                        .spawn().unwrap();
let stdout = child.stdout.take().unwrap();
let mut noblock_stdout = NonBlockingReader::from_fd(stdout).unwrap();
while !noblock_stdout.is_eof() {
    let mut buf = String::new();
    noblock_stdout.read_available_to_string(&mut buf).unwrap();
    std::thread::sleep(Duration::from_secs(5));
}
