Until I read the doc and find how to limit the retention,
otherwise it just eats all my ram and cpu and things start to fall
apart.

+Reassemble the content of the buffer (buf, blen) which should be
+in the HTTP chunked encoding, by collapsing data chunks to the
+beginning of the buffer.
+
+If chunks get reassembled, modify hm->body to point to the reassembled
+body and fire MG_EV_HTTP_CHUNK event. If handler sets MG_F_DELETE_CHUNK
+in nc->flags, delete reassembled body from the mbuf.
+
+Return reassembled body size.
