db45bd5e82 Reinstate the mechanism in BETWEEN that avoids evaluating the first expression

84b19a3da1 The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated 
once.  That is no longer true, and so some tests are failing.  This needs to

cc15313cc9 Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. 
When enabled, the "unknown function" error is suppressed for EXPLAIN and
a no-op function named "unknown()" is substituted.  This facilitiates using
the command-line shell to analyze queries from applications that contain
many application-defined functions that are not normally available to the
shell.
