lib, vtysh: support multiple VRFs by using linux netns
We realize VRFs with linux netns by default. The main job is
to associate a VRF with a netns. Currently this is done by
the configuration:
[no] vrf N netns <netns-name>
This command is also available in vtysh and goes to only
zebra, because presently only zebra supports multiple VRF.
A file descriptor is added to "struct vrf". This is for the
associated netns file. Once the command "vrf N netns NAME"
is executed, the specified file is opened and the file
descriptor is stored in the VRF N. In this way the
association is formed.
In vrf_socket(), we first switch to the specified VRF by
using the stored file descriptor, and then can allocate
a socket which is working in the associated netns.
