  Changed paths:
    M src/lxc/lxc-ls
    M src/lxc/lxc_info.c
    M src/lxc/lxccontainer.c

  Log Message:
  -----------
  make lxcapi_get_interfaces and lxcapi_get_ips unprivileged container aware

Based on Stéphane's suggestion, those two API methods now;

* fork a new process,
* switch to appropriate namespace(s),
* do what we want,
* return the data over a pipe to the parent which returns the result to the original caller.

For the whole thread please see;

This patch also makes lxc-ls and lxc-info call those functions.

I'm adding Stéphane as an author here since both the idea as well as
the initial setns code come from him.
