[PATCH net-2.6.25 4/19] [NETNS] Add namespace to API for routing /proc entries creation.

["Denis V. Lunev" <den-GEFAQzZX7r8dnm+yROfE0A@public.gmane.org>]

This adds netns parameter to fib_proc_init/exit and replaces __init specifier
with __net_init. After this, we will not yet have these proc files show info
from the specific namespace - this will be done when these tables become
namespaced.
