Make sql_mode=NO_AUTO_VALUE_ON_ZERO default for Drizzle.

Also fix DEFAULT keyword handling for auto-increment so that it defaults to
NULL and not 0 so that the following is valid and generates two auto-inc
values:

create table t1 (a int auto_increment primary key)
insert into t1 (a) values (default);
insert into t1 (a) values (default);

Important to note that 0 is no longer magic. So this gives you duplicate
primary key error:

insert into t1 (a) values(0);
insert into t1 (a) values(0);

as you've inserted the explicit value of 0 twice.
