Michael Crosby 044e298507 Improve error handling in runc
The error handling on the runc cli is currenly pretty messy because
messages to the user are split between regular stderr format and logrus
message format.  This changes all the error reporting to the cli to only
output on stderr and exit(1) for consumers of the api.

By default logrus logs to /dev/null so that it is not seen by the user.
If the user wants extra and/or structured loggging/errors from runc they
can use the `--log` flag to provide a path to the file where they want
this information.  This allows a consistent behavior on the cli but
extra power and information when debugging with logs.

This also includes a change to enable the same logging information
inside the container's init by adding an init cli command that can share
the existing flags for all other runc commands.

Phil Estes 178bad5e71 Properly setuid/setgid after entering userns
The re-work of namespace entering lost the setuid/setgid that was part
of the Go-routine based process exec in the prior code. A side issue was
found with setting oom_score_adj before execve() in a userns that is
also solved here.

Ido Yariv 78f5148c67 Fix handling of unsupported namespaces
currentState() always adds all possible namespaces to the state,
regardless of whether they are supported.
If orderNamespacePaths detects an unsupported namespace, an error is
returned that results in initialization failure.

Fix this by only adding paths of supported namespaces to the state.

Doug Davis 3e46977ec1 Fix to allow for build in different path
The path in the stacktrace might not be:
  "github.com/opencontainers/runc/libcontainer/stacktrace"
For example, for me its:
  "_/go/src/github.com/opencontainers/runc/libcontainer/stacktrace"
so I changed the check to make sure the tail end of the path matches instead
of the entire thing

Kenfe-Mickael Laventure 6325ab96e7 Call Prestart hook after namespaces have been set
This simply move the call to the Prestart hooks to be made once we
receive the procReady message from the client.

This is necessary as we had to move the setns calls within nsexec in
order to be accomodate joining namespaces that only affect future
children (e.g. NEWPID).
