coda: Restrict coda messages to the initial pid namespace
Remove the slight chance that pids in coda messages will be
interpreted in the wrong pid namespace.
- Explicitly send all pids in coda messages in the initial pid
namespace.
- Only allow mounts from processes in the initial pid namespace.
- Only allow processes in the initial pid namespace to open the coda
character device to communicate with coda.
