Add the pointer-type parameter to sqlite3_bind_pointer(),

sqlite3_result_pointer(), and sqlite3_value_pointer().  The pointer type is
a static string that must match (according to strcmp()) or else the pointer
is passed as a NULL.  This is a security measure to prevent crossing pointers
between different extensions.
