…erver::post_iterator multiple times with chunnks of post data and successibe offsets. Currently, set_arg will overwrites the value. So after all the successive post_iterator calls, the value will be set to the last chunk. This change fixes the set_arg() function(s).. by checking for existing value and appending to it than overwriting it.

Modifying set_args this way means that if there is an key that is both a url parameter and a POST parameter, as in this curl call
then the url parameter value for the key |

For a POST parameter with a large value, libmicrohttpd will call webserver::post_iterator
multiple times with chunks of post data and successive offsets. Currently, set_arg will
overwrites the value. So after all the post_iterator calls, the value will be
set to the last chunk.
This change fixes the set_arg() function(s).. by checking for an existing value and appending the new chunk.
the bug can be tested with the following script.
