Sendfile for Tokio

:Status: alpha :Documentation: http://docs.rs/tk-sendfile

A thread pool that can process file requests and send data to the socket with zero copy (using sendfile).

Challenges:

1. While sendfile is non-blocking when writing to socket, it blocks for
   disk access for two cases: initial open() and for reading file inside
   the sendfile() system call itself
2. Doing more than single sendfile operation requires some bookkeeping
3. It should be possible to implement file cache (both opened files and
   in-memory file data) transparently for the user
4. [TODO] Serving user-specified file paths requires non-trivial code to
   prevent symlink attacks
