Note: Prior to the MPM-as-DSO churn, the following MPMs did not enable this logic:

  WinNT       APR supports no-oping the setsockopt() based on inheriting Nagle from the 
              listening socket on this platform, so the new APR call will be a no-op.
  simple      same as WinNT for at least some Unix-y platforms
  BeOS        shrug

a string can't be used as the declined value since the hook macro must compare 
retcodes from hooks with that declined value

(thanks, gcc/Joe)

accommodate in ap_show_mpm() since we don't want to return NULL to the caller of
this simple API

output from what people/scripts expect)

(The set of MPMs modified is the same set for which mod_unixd is enabled,
which is approximately equivalent to the set of Unix MPMs which anybody has
tried to maintain in recent memory.)
