Merge branch 'master' of /git/quagga.euro-ix into pipeworkex16p

This ensures that the two branches are consistent after the merging
of the old-Quagga 0.99.18 changes.

Release: 0.99.18ex16p.

Eliminated some whitespace differences !

Collected RESTRICTED_NODE show_bgp_ipv6_safi_route_cmd and
show_bgp_ipv6_safi_prefix_cmd, and one HAVE_IPV6 skip.  Also releasing
filename in closezlog().

Removed strlen() from lib/qfstring.c for async-signal-safe purposes.
