5517625960 Remove dead code from the lemon-generated parser. Better testing
of the sqlite3_file_control() interface, and in particular make sure
the interface works on :memory: databases. (CVS 4738)

b19fd012b0 Lemon change: compile the resulting parser with -DYYSTACKDEPTH=0 or set
the "%stack_size" parameter to 0 in the grammar and the parser stack
will be dynamically allocated using realloc() and free().  The default
behavior is to have a finite depth stack. (CVS 3738)

cb6c565eab Additional memory initialization in lemon - bug reported from wireshark.
Ticket #2172.  Note this problem only comes up with certain grammars,
and does not impact SQLite.  On the other hand, it might cause SQLite
to run slower.  So we might want to revisit this change at some point. (CVS 3594)
