** The following three macros, FUNCTION(), LIKEFUNC() and AGGREGATE() are
** used to create the initializers for the FuncDef structures.

** FUNCTION(zName, nArg, iArg, bNC, xFunc)
** Used to create a scalar function definition of a function zName
** implemented by C function xFunc that accepts nArg arguments. The
** value passed as iArg is cast to a (void*) and made available
** as the user-data (sqlite3_user_data()) for the function. If
** argument bNC is true, then the FuncDef.needCollate flag is set.
**
** AGGREGATE(zName, nArg, iArg, bNC, xStep, xFinal)
** Used to create an aggregate function definition implemented by
** the C functions xStep and xFinal. The first four parameters
** are interpreted in the same way as the first 4 parameters to
** FUNCTION().

** LIKEFUNC(zName, nArg, pArg, flags)
** Used to create a scalar function definition of a function zName
** that accepts nArg arguments and is implemented by a call to C
** function likeFunc. Argument pArg is cast to a (void *) and made
