+decoding and to retrive form data from raw http messages.

+Decode an urlencoded string - optionally without decoding
+
+the "+" sign to " " - and return the decoded string.
+@class function
+@name urldecode
+@param str		Input string in x-www-urlencoded format
+@param no_plus	Don't decode "+" signs to spaces
+@return			The decoded string
+@see				urlencode

+---[[
+Extract and split urlencoded data pairs, separated bei either "&" or ";"
+
+from given url or string. Returns a table with urldecoded values.
+Simple parameters are stored as string values associated with the parameter
+name within the table. Parameters with multiple values are stored as array
+containing the corresponding values.
+@class function
+@name urldecode_params
+@param url	The url or string which contains x-www-urlencoded form data
+@param tbl	Use the given table for storing values (optional)
+@return		Table containing the urldecoded parameters

+in the params table withing the given message object. Multiple parameter
+values are stored as tables, ordinary ones as strings.
+If an optional file callback function is given then it is feeded with the
+file contents chunk by chunk and only the extracted file name is stored
+within the params table. The callback function will be called subsequently
+with three arguments:
+ o Table containing decoded (name, file) and raw (headers) mime header data
+ o String value containing a chunk of the file data
+ o Boolean which indicates wheather the current chunk is the last one (eof)
