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.

dd545d3bf2 Make sure the ORDER BY LIMIT optimization is not applied if the inner-most 
loop can only have a single iteration and is hence not really a loop.

added by check-in [bf46179d44843].
