[ticket/10349] Removed duplicated functions from schema loading in tests
[ticket/10349] Update function comment
[ticket/10349] Use new schema comment function in installer
[ticket/10349] Unit tests: Consolidate schema comment removal functions
[ticket/10349] Unit tests: Remove comments while loading schema files
Perform the same operations that the installer does when preparing the schema
files. These functions come straight from /includes/functions_install.php and
/includes/functions_admin.php.

If database tests cannot be run the error message is ambigous. This
commit makes it clearer:
- whether the supplied dbms is supported by us
- which dbms are supported by us
- whether the required PDO extension is loaded
PHPBB3-10043
Move most of the methods to a separate connection manager class. The
test case creates a manager to handle database creation, schema loading
and more. Most of the methods could be simplified because they can
access shared pdo, config and dbms data.
