7a429658d7 Fix harmless compiler warning in LEMON. 
FossilOrigin-Name: f61a70589ac7e05008a362bd9d5b7bde5d07a758

03e1b1f5ff In LEMON, limit the size of the grammar file to 100MB. This ensures that 
the program will never experience integer overflow.  To be doubly sure,
use calloc() instead of malloc() when allocating arrays.

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.)

61f92cd045 In LEMON, fix a bug in the text formatter introduced by the previous 
commit.  Also add the new "%token_class" directive for defining symbolic
names that stand any one of a collection of tokens.

7dd1ac600e Fix a bug in lemon in computation of which non-terminals can generate an 
empty string.  This bug and the fix make absolutely no difference for the
grammar used by SQLite, but it can make a difference when lemon is used
in other grammars.
