[ticket/14789] Remove obsolete check_form_key() and add missing hashes
[ticket/14789] Move form key checks to where they actually do something
This will further harden the ACP security by adding link hashes to links and
form tokens to forms that did not have these yet and result in modified
settings or write action on the filesystem or database. These few links and
forms were still relying on the global ACP protection, mainly due to them
not posing further risks of compromising data. After this change these will
now also be properly protected against tampering.

The class result_mssqlnative was removed in ticket 11980. This removes
the dependency on that class from the database backup utility. It is
possible to use the sqlsrv functions to retrieve the field information,
but they must be then mapped back to type names. That mapping was removed
in 11980 and it is easier to just look it up in the information schema
table.

[ticket/10611] Filter out not existing database tables when making a backup.
[ticket/10611] Use phpbb_db_tools::sql_list_tables() instead of get_tables().
[ticket/10611] Generate db_tools instance in acp_database module.
Using $this->db_tools->sql_list_tables() as the first argument gives us table
names as array keys as a by-product which might be useful at some point.
