Fix "show ip bgp dampened-paths" garbage output.
* bgpd/bgp_damp.c: Make bgp_damp_reuse_time_vty() accept a buffer and length, rather than returning a local var buffer whose contents can get trounced. Remove duplicate BGP_UPTIME_LEN define. * bgpd/bgp_damp.h: bgp_damp_reuse_time_vty() prototype change. * bgpd/bgp_route.c: Provide bgp_damp_reuse_time_vty() with a buffer and length. Remove duplicate BGP_UPTIME_LEN define. This problem was noticed in 2005... http://hibernia.jakma.org/~paul/patches/quagga-test.diff ...but the fix didn't make it into the code.
