Dan Walsh 12934ef3a4 Fix SELinux errors caused by multi-threading 
Occasionally the selinux_test program will fail because we are setting file
context based on the Process ID but not the TID.  THis change will always
use the TID to set SELinux labels.

Dan Walsh b7942ec2ca This patch reworks the SELinux patch to be only run on demand by the daemon 
Added --selinux-enable switch to daemon to enable SELinux labeling.

The daemon will now generate a new unique random SELinux label when a
container starts, and remove it when the container is removed.   The MCS
labels will be stored in the daemon memory.  The labels of containers will
be stored in the container.json file.

When the daemon restarts on boot or if done by an admin, it will read all containers json files and reserve the MCS labels.

A potential problem would be conflicts if you setup thousands of containers,
current scheme would handle ~500,000 containers.

Tianon Gravi d98069030d 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.

Alexander Larsson 1fb0bf1b3b 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.

Solomon Hykes d4920b3fff beam/examples/beamsh: basic implementation of the pipeline design, with static handlers for now. 
In the pipeline design, several beam commands can be run concurrently,
with their respective inputs and outputs connected in such a way that
beam messages flow from the first to last. This is similar to the way
a unix shell executes commands in a pipeline: instead of STDIN and
STDOUT, each beam command has a "BEAMIN" and "BEAMOUT".

Since beam allows for richer communication than plain byte streams, beam
pipelines can express more powerful computation, while retaining the
fundamental elegance and ease of use of unix-style composition.

This inserts low-level hooks for interactive step-by-step debugging.
Hooks are triggered by setting the *TEST* environment variable.

double-closing, or other issues which are difficult to debug with
the usual toolbox.
