Move this out of here once Stew's done with UDF breakout. The following headers need it:
393
sql_lex.h --> included by sql_class.h
411
* @TODO Move to a separate header?
413
* It's needed by item.h and field.h, which are both inter-dependent
414
* and contain forward declarations of many structs/classes in the
417
* What is needed is a separate header file that is included
418
* by *both* item.h and field.h to resolve inter-dependencies
420
* But, probably want to hold off on this until Stew finished the UDF cleanup
