Review request for mesos, Benjamin Hindman, Jie Yu, and Vinod Kone.


Updated to include full functionality for dynamically adding multiple `fd` targets and writing
to them asynchronously (though no one actually calls these functions yet). Also added code
to dynamically change the read end of the stdin stream so we can eventually allow this to
be swapped out based on `attachInput` calls.

Bugs: MESOS-6467

Repository: mesos


Currently, this process simply intercepts the stdout/stderr of a
container and writes it to the stdout/stderr FDs set up by the
container logger. In future commits, this process will be expanded to
allow dynamically attaching new input / output sources to a container
to support `docker attach` like functionality for a running container.
