ecaa9d399c Add the "%token_class" directive to the LEMON parser generator. This opens up 
the possibility of simplifying the parser.  Also remove all calls to 
sprintf(), strcpy(), and strcat() from LEMON to avoid compiler warnings
on OpenBSD.  (Aside:  It is this change to avoid harmless compiler warnings
that was the cause of the reason spat of bugs.)

vdbeExecUnion object that reduces the size of the sqlite3VdbeExec()
stack frame unless the SQLITE_SMALL_STACK compile-time option is
specified as on of the OPTS in the makefile.  The vdbeExecUnion object
gets in the way of C-compiler optimizer and results in slightly slower code.
