nature of its output, it uses the $smcFunc['db_query']() function without __FILE__ or
__LINE__ so errors won't be outputted.
void DumpDatabase2()
- writes all of the database to standard output.
- uses gzip compression if compress is set in the URL/post data.
- may possibly time out in some cases.
- the data dumped depends on whether "struct" and "data" are passed.
- requires an administrator and the session hash by post.
- is called from ManageMaintenance.php.
