conf: introduce lxc.rootfs.managed 
This introduces a new config key lxc.rootfs.managed which can be used to
indicate whether this LXC instance is managing the container storage. If LXC is
not managing the storage then LXC will not modify the container storage.
For example, an API call to c->destroy(c) will then run any destroy hooks but
will not destroy the actual rootfs (Unless, of course, the hook does so behind
LXC's back.).

e4b3e369f8 Unprivileged's incompatibility with type=none docs 
Unprivileged containers are not compatible with sharing the
host namespace due to an inability to mount sysfs. Add docs
in lxc.container.conf to document that out.

nl: avoid NULL pointer dereference

nl: avoid NULL pointer dereference 
It's a valid case to call nla_put() with NULL data and 0 len. It's done e.g. in
the nla_put_attr().

There has to be a check for data in nla_put() as passing NULL to the memcpy()
is not allowed. Even if length is 0, both pointers have to be valid.

For a reference see C99 standard (7.21.1/2), it says: "pointer arguments on
such a call shall still have valid values".
