Add a method to get all values of HTTP header defined as list

According to RFC 2616 [1] header field names are case insensitive.
Header fields defined as a comma separated list can have multiple header
fields with the same field name. Add a method to HttpConnection which
retrieves all values with a given header field name with the field name
compared case insensitive.
