Finally commit the transparent-as and nexthop no-modify stuff I wrote on the

way to FOSDEM. With transparent-as set to ye bgpd will not prepend his own
AS for sent updates. NB the neighbor needs to set "enforce neighbor-as no"
or it will not like the received AS paths. With set nexthop no-modify bgpd
will change the nexthop as done normaly.
OK henning@ man page update with help of jmc@
