since no consensus could be found yet for a new command line option to
ifconfig, heck, not even about wether it is needed, I propose this for
now.
1) make "ifconfig <if> inet6 eui64" reset the NOINET6 flag
unconditionally, so a link-local will be assigned if there isn't one
yet.

2) turn the NOINET6 flag on by default.
As said previously, it will be reset and thus a link-local assigned
transparently if either
-rtsol(d) is run
-an inet6 address is assigned
-ifconfig <if> inet6 eui64 is run
and thus should be entirely transparent for the vast majority of inet6
users.

wether we need a less obscure ifconfig command than eui64 can be
discussed after.
oks?
