Warn unrecognized sections in the config file

In the config file, sections are specified by square bracket pair "[]"$,
or included in the option name itself which separated by a period"(.)".

Typicaly, [testnet] is not a correct section name and specified options
in that section are ignored but user cannot recognize what is happen.

So, add some log/stderr-warning messages if unrecognized section names
are present in the config file after checking section only args.
