Several final namespace changes.  Exports (with an ap_ prefix!) the
  useful sendwithtimeout/recvwithtimeout symbols.  How useful?  SSL needs
  them, and proxy_connect should probably use them as well.  And corrects
  two newly exported (never released) symbols since they did not require
  the _NONSTD semantics.
