Remove old docs, rename docs_new to docs

It would be probably good idea to also remove tools/docgen.py and
asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which
may contain some useful info which we'll need at least to review before
removing.

+---
+
+Create a DNS reply.
+
+The reply will be based on an existing query message `msg`.
+The query body will be appended to the output buffer.
+"reply + recursion allowed" will be added to the message flags and
+message's num_answers will be set to 0.
+
+Answer records can be appended with `mg_dns_send_reply` or by lower
+level function defined in the DNS API.
+
+In order to send the reply use `mg_dns_send_reply`.
+It's possible to use a connection's send buffer as reply buffers,
+and it will work for both UDP and TCP connections.
+
+Example:
+
+```c
+reply = mg_dns_create_reply(&nc->send_mbuf, msg);
+for (i = 0; i < msg->num_questions; i++) {
+  rr = &msg->questions[i];

+Uncompress a DNS compressed name.
+
+The containing dns message is required because the compressed encoding
+and reference suffixes present elsewhere in the packet.
+
+If name is less than `dst_len` characters long, the remainder
+of `dst` is terminated with `\0' characters. Otherwise, `dst` is not
+*terminated.
+
+If `dst_len` is 0 `dst` can be NULL.
+Return the uncompressed name length.

+`url` is a URL to fetch. It must be properly URL-encoded, e.g. have

+is created with the specified POST data. Note that if the data being posted
+is a form submission, the `Content-Type` header should be set accordingly
+(see example below).

+---
+
+Send response line and headers.
+This function sends response line with the `status_code`, and automatically
+sends one header: either "Content-Length", or "Transfer-Encoding".
+If `content_length` is negative, then "Transfer-Encoding: chunked" header
+is sent, otherwise, "Content-Length" header is sent.
+
+NOTE: If `Transfer-Encoding` is `chunked`, then message body must be sent
+using `mg_send_http_chunk()` or `mg_printf_http_chunk()` functions.
+Otherwise, `mg_send()` or `mg_printf()` must be used.
+Extra headers could be set through `extra_headers` - and note `extra_headers`
+must NOT be terminated by a new line.

+signature: |
+  void mg_send_http_chunk(struct mg_connection *nc, const char *buf, size_t len);
+---
+
+Send buffer `buf` of size `len` to the client using chunked HTTP encoding.
+This function first sends buffer size as hex number + newline, then
+buffer itself, then newline. For example,
+  `mg_send_http_chunk(nc, "foo", 3)` whill append `3\r\nfoo\r\n` string to
+the `nc->send_mbuf` output IO buffer.
+
+NOTE: HTTP header "Transfer-Encoding: chunked" should be sent prior to
+using this function.
+
+NOTE: do not forget to send empty chunk at the end of the response,
+to tell the client that everything was sent. Example:
+
+```
+  mg_printf_http_chunk(nc, "%s", "my response!");
+  mg_send_http_chunk(nc, "", 0); // Tell the client we're finished

+
+Send response status line.
+If `extra_headers` is not NULL, then `extra_headers` are also sent

+---
+
+Attach built-in HTTP event handler to the given connection.
+User-defined event handler will receive following extra events:
+
+- MG_EV_HTTP_REQUEST: HTTP request has arrived. Parsed HTTP request
+ is passed as
+  `struct http_message` through the handler's `void *ev_data` pointer.
+- MG_EV_HTTP_MULTIPART_REQUEST: A multipart POST request has received.
+  This event is sent before body is parsed. After this user
+  should expect a sequence of MG_EV_HTTP_PART_BEGIN/DATA/END requests.
+  This is also the last time when headers and other request fields are
+  accessible.
+- MG_EV_HTTP_REPLY: HTTP reply has arrived. Parsed HTTP reply is passed as
+  `struct http_message` through the handler's `void *ev_data` pointer.
+- MG_EV_HTTP_CHUNK: HTTP chunked-encoding chunk has arrived.
+  Parsed HTTP reply is passed as `struct http_message` through the
+  handler's `void *ev_data` pointer. `http_message::body` would contain
+  incomplete, reassembled HTTP body.
+  It will grow with every new chunk arrived, and
+  potentially can consume a lot of memory. An event handler may process
+  the body as chunks are coming, and signal Mongoose to delete processed
+  body by setting `MG_F_DELETE_CHUNK` in `mg_connection::flags`. When
+  the last zero chunk is received,
+  Mongoose sends `MG_EV_HTTP_REPLY` event with
+  full reassembled body (if handler did not signal to delete chunks) or
+  with empty body (if handler did signal to delete chunks).
+- MG_EV_WEBSOCKET_HANDSHAKE_REQUEST: server has received websocket handshake
+  request. `ev_data` contains parsed HTTP request.
+- MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed Websocket handshake.
+  `ev_data` is `NULL`.
+- MG_EV_WEBSOCKET_FRAME: new websocket frame has arrived. `ev_data` is
+  `struct websocket_message *`
+- MG_EV_HTTP_PART_BEGIN: new part of multipart message is started,
+  extra parameters are passed in mg_http_multipart_part
+- MG_EV_HTTP_PART_DATA: new portion of data from multiparted message
+  no additional headers are available, only data and data size
+- MG_EV_HTTP_PART_END: final boundary received, analogue to maybe used to
+  find the end of packet
+  Note: Mongoose should be compiled with MG_ENABLE_HTTP_STREAMING_MULTIPART
+  to enable MG_EV_HTTP_MULTIPART_REQUEST, MG_EV_HTTP_REQUEST_END,
+  MG_EV_HTTP_REQUEST_CANCEL, MG_EV_HTTP_PART_BEGIN, MG_EV_HTTP_PART_DATA,

+Mbufs are mutable/growing memory buffers, like C++ strings.
+Mbuf can append data to the end of a buffer, or insert data into arbitrary

+signature: |
+  void mg_mqtt_broker(struct mg_connection *brk, int ev, void *data);
+---
+
+Process a MQTT broker message.
+
+Listening connection expects a pointer to an initialized `mg_mqtt_broker`
+structure in the `user_data` field.
+
+Basic usage:
+
+```c
+mg_mqtt_broker_init(&brk, NULL);
+
+if ((nc = mg_bind(&mgr, address, mg_mqtt_broker)) == NULL) {
+  // fail;
+}
+nc->user_data = &brk;
+```
+
+New incoming connections will receive a `mg_mqtt_session` structure
+in the connection `user_data`. The original `user_data` will be stored
+in the `user_data` field of the session structure. This allows the user
+handler to store user data before `mg_mqtt_broker` creates the session.
+
+Since only the MG_EV_ACCEPT message is processed by the listening socket,
+for most events the `user_data` will thus point to a `mg_mqtt_session`.
