[AD] Reading config strings var="val"

[Stepan Roh <sroh7497@xxxxxxxxxx>]

I did an enhancement to src/config.c:get_config_string() to be able to use
var="val" syntax in config files. Diff is in attached file. But it breaks
up a backward compatibility, because when there is "str" it uses static
buffer and it seems working but nobody knows. It can't be added just into
loading of config, because "a","b" can be a","b for get_config_string()
and a,b for get_config_argv.
