7c4942cb1a Fix the dbhash utility so that it ignores the root page number when hashing 
the sqlite_master table.  Add new command-line options.  Add the ability to
hash multiple databases with a single command.

4ef07708df Enhance Lemon so that it reorders the reduce rules such that rules without

to run faster.
