Currently, all ipv6 addresses are flushed when the interface is configured

Add a new sysctl to make this behavior optional. The new setting defaults to
flush all addresses to maintain backwards compatibility. When the setting is
reset global addresses with no expire times are not flushed:
does src addr selection also need to be modified to know if/when it can/cannot
use this static address as a source addr? Or does the TENTATIVE flag
make it Do The Right Thing per rfc 3484?
When the device is set 'down' (admin state) all routes (including cached
ones) for the device are cleared so there should not be any way to
select the source address that is saved. i.e, ipv6_dev_get_saddr()
should not get invoked for the device.
