everything inside a "quoted strings" section to support quoted strings,
and I am not 100% sure we can easily support that because different
options use different token parsers.
# start new quoting support section
configuration_value_parser quoted_strings

2b) Add squid.conf directives _at the beginning_ of the conf file
to specify the parser behavior. So do not toggle and force the admin
to be aware of quoted strings and _must_ check the whole config file himself.
The default value of "config_used_quoted_strings" is "off".
This is still 100% backwards compatible without doing lots (?) of effort
to please everybody and every situation.
