0ede9ebec7 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
the "HAVE_component" compile-time options.

18b67f3f0d Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides 
minimal performance improvements, and then only at SQL preparation time, not
at runtime, and it has problems with data races in shared-cache mode.  We might
later add the keyinfo cache back but only enable it when shared-cache mode
is off.
