Andrew Gallatin a18f34fe77 Don't request CTLTYPE_OPAQUE if we can't print them. ... The intent is to skip expensive opaque sysctls like tcp_pcblist unless they are explicitly requested. Sysctl nodes like this don't show up in sysctl -a, but they do generate output that winds up being dropped, unless the user specifically requested binary/hex output or opaques. This reduces the runtime of sysctl in many circumstances on a loaded system. It also reduces the likelihood that simply gathering diagnostics on a sick machine (stuck lock, etc) via sysctl -a might push it over the edge into a total lockup.
