  Log Message:
  -----------
  Allow autodev without a rootfs

A container without a rootfs is useful for running a collection of
processes in separate namespaces (to provide separate networking as
an example), while sharing the host filesystem (except for specific
paths that are re-mounted as needed). For multiple processes to run
automatically when such a container is started, it can be launched
using lxc-start, and a separate instance of systemd can manage just
the processes inside the container. (This assumes that the path to
the systemd unit files is re-mounted and only contains the services
that should run inside the container.) For this use case, autodev
should be permitted for a container that does not have a rootfs.

  Log Message:
  -----------
  Only mount /proc if needed, even without a rootfs

Use the same code with and without a rootfs to check if mounting
/proc is necessary before doing so. If mounting it is unsuccessful
and there is no rootfs, continue as before.

  When creating container, save configuration if rootfs already exists

Commit 6c6892b "fix multithreaded create()" prevented the container
configuration from being saved if the backing store does not need
to be created.
