c54bc4ca04 Remove "root" and "" special cases in libcontainer 
These are unnecessary since the user package handles these cases properly already (as evidenced by the LXC backend not having these special cases).

I also updated the errors returned to match the other libcontainer error messages in this same file.

Also, switching from Setresuid to Setuid directly isn't a problem, because the "setuid" system call will automatically do that if our own effective UID is root currently: (from `man 2 setuid`)

    setuid() sets the effective user ID of the calling process.  If the
    effective UID of the caller is root, the real UID and saved set-user-
    ID are also set.

bcfc527abb Separating cgroup Memory and MemoryReservation.

cd911b83ce beam: Fix double close of fds in SendUnix 
Instead of calling syscall.Close() on the fds in sendUnix() we call
Close() on the *os.File in Send(). Otherwise the fd will be closed, but
the *os.File will continue to live, and when it is finalized the
fd will be closed (which by then may be reused and can be anything).

This also adds a note to Send() the the file is closed.

5220dbeffd beam/examples/beamsh: commands are messages. 
Commands in the pipeline should either implement or pass-through command messages.

This amounts to a proof-of-concept implementation of the "pipeline"
design of Docker plugins.
