Only do the specialized MacOS single-core zone_malloc initialization if
compiled with the SQLITE_MIGHT_BE_SINGLE_CORE flag. This avoids a (harmless)
warning about OSAtomicCompareAndSwapPtrBarrier()

Improvements to compile-time-option hygiene. Use "#if OPTION" instead of
"#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work.

Add the "Have-Not" configuration in releasetest.tcl which disables all of
