In order to allow nice usage statistics (in terms of percentages and
other such data), add the value of pids.max to the PidsStats struct
returned from the pids cgroup controller.

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.

just so that we're not merging code into master w/o any tests at all.
I expect this to be removed once we have a real testing infrastructure.

Now that all the user namespace code is moved into C, these routines are
no longer used.

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.

This commit adds support to libcontainer to allow caps, no new privs,
apparmor, and selinux process label to the process struct so that it can
be used together of override the base settings on the container config
per individual process.

This bump of the spec includes a change to the deivce type to be a
string so that it is more readable in the json serialization.
It also includes the change were caps, no new privs, and process
labeling features are moved from the container config onto the process.
