Permit pool size of /64.../112 for ifconfig-ipv6-pool

(Leftover check from the early days where --server-ipv6 also only
accepted /64 - nowadays we handle smaller pools just fine)

Fix parameter listing in non-debug builds at verb 4

When built with enable_debug=no, the parameter output expected at --verb
4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible
code sections. This appears to be a mistake when looking at the
configure help text for enable_small and enable_debug.

This change keys the relevant code off of enable_small instead,
including the parameter listing when enale_small=no (the
configure-script default.) Most of this code is in options.c, with some
callers present in plugin.c/h and route.c/h. No function code is
changed, just the #ifdef values to use the small feature instead of
debug.

This means builds no longer need enable_debug=yes in order to get the
expected log output at verb 4.
