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

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.

When displaying the default value for a numeric custom profile field, only use
request_var to obtain the value on creation. When editing, it will always
override the actual value with an empty string, as this is request_var's default
return value.
