Add a variant of evhttp_send_reply_chunk() with a callback on evhttp_write_buffer()
evhttp_write_buffer() used by evhttp_send_reply_chunk() can take callback executed when (part of) the buffer has been written. Using this callback to schedule the next chunk avoids buffering large amounts of data in memory.
