implement support for fast hello packets.
if route-dead-time is set to "minimal" (rather than a number of
seconds), the dead time is set to 1 second and hellos are sent at
the interval specified by fast-hello-interval in msecs. this is non
standard wrt to the ospf rfc, but it does interoperate with at least
one other router vendor.
this allows much better responsiveness to l3 topology changes than
the standard intervals allow. if i yank a cable to one of my
upstreams, the routes adjust in a second rather than the default
of 40 i was running with before. the users dont even notice something
changed.
developed while working with joshua atterbury.
ok claudio@ as part of a larger diff.
dedicated to zan rowe who thinks she is a bigger nerd than me.
