The "takeys" table was only created for existing databases.
New databases were immediately marked as version "8" databases
and the tykeys table creation was skipped.
The ta-key will be generated on-demand and assigned to the
issuing CA. All issued certificates of this CA will use the
same ta-key.
It can be exported as single file and will also be part of the
exported openvpn configuration file.
Extend export tests to validate the output of ta-keys
and adapt the OpenVPN conf file export test to also check the ta-key.
Because generally using QString.arg() results in an error for
strings without %1
Also use the static database() function instead of creating
a temporary instance during close.
Extend B64_BLOB from "VARCHAR(8000)" which was a good
common value - until I realized that CRL may become pretty large.
Use "TEXT" for all databases but MariaDB, where LONGTEXT is used.
Add database type check via SQL query to detect the
correct database even behind an ODBC Driver.
