Implemented uploading of file for PUT and POST requests
Refactored LIBCURL_HTTP_CLIENT_REQUEST to free used pointer, and also ease extension of the class if needed.
Updated cURL library with addition of {CURL_EXTERNALS}.slist_free_all (..)
Renamed any *_APPLICATION as *_SERVICE
mainly because those components
such as WSF_APPLICATION, renamed as WSF_SERVICE
are not always the main application entry, and "service" describe them better
Minor implementation change in WSF_REQUEST
