Drop explicit initializers from the constructors.
- Fix indentations of section declarators.
- Replace NULL by nullptr when feasible.
- Sort private section: properties first, then methods.
New classes:
- database_model: Manage the database tables (keys, req, cert, crl, templ)
extracted from widgets/MW_database.cpp
- arguments: parse commandline, dynamically create help text
Add ODBC QSQL Database driver
Column "public" in public_keys table is a keyword in
MSSQL. Double quote it.
Double quotes are invalid on MySQL in non-ANSI mode.
Force ANSI mode for MySQL/MariaDB databases.
MSSQL also has a maximum VARCHAR of 8000
Schema updates are not performed for each new database.
New databases are immediately created conforming to schema:7
Schema 5 and 6 get updated to 7.
Schemas < 5 never have been released officially. (pre 2.0.0)
Switch "Database name" label to "DSN" for ODBC databases.
