nix::poll::PollFd currently only exposes revents(). However, there is no way to get to the actual fd because libc::pollfd is private. I think a function like:

impl PollFd {
pub fn fd(&self) -> RawFd { self.pollfd.fd }
}
or similar would be useful.
As it stands, I dont really know how to figure out which event belongs to which fd.

1516: Implement AsRawFd for PollFd r=asomers a=cemeyer

Implement the trait on PollFd, providing an `as_raw_fd()` accessor to
get the RawFd associated with the PollFd.

Subsumes #1147, #1286.  Closes #1146.

Test: `cargo test --test test test_pollfd_fd`
