-Parses CoAP message and fills mg_coap_message and returns cm->flags.
-This is a helper function.
-
-NOTE: usually CoAP works over UDP, so lack of data means format error.
-But, in theory, it is possible to use CoAP over TCP (according to RFC)
-
-The caller has to check results and treat COAP_NOT_ENOUGH_DATA according to
-underlying protocol:
-
-- in case of UDP COAP_NOT_ENOUGH_DATA means COAP_FORMAT_ERROR,
-- in case of TCP client can try to receive more data

----
-
-Creates 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 the
-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 a reply use `mg_dns_send_reply`.
-It's possible to use a connection's send buffer as reply buffer,
-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];
-  if (rr->rtype == MG_DNS_A_RECORD) {
-    mg_dns_reply_record(&reply, rr, 3600, &dummy_ip_addr, 4);

-This function mutates the content of that buffer in order to ensure that
-the DNS header reflects the size and flags of the message, that might have
-been updated either with `mg_dns_reply_record` or by direct manipulation of
-`r->message`.
-
-Once sent, the IO buffer will be trimmed unless the reply IO buffer
-is the connection's send buffer and the connection is not in UDP mode.

----
-
-Helper function that creates an outbound WebSocket connection.
-
-`url` is a URL to connect to. It must be properly URL-encoded, e.g. have
-no spaces, etc. By default, `mg_connect_ws()` sends Connection and
-Host headers. `extra_headers` is an extra HTTP header to send, e.g.
-`"User-Agent: my-app\r\n"`.
-If `protocol` is not NULL, then a `Sec-WebSocket-Protocol` header is sent.
-
-Examples:
-
-```c
-  nc1 = mg_connect_ws(mgr, ev_handler_1, "ws://echo.websocket.org", NULL,
-                      NULL);
-  nc2 = mg_connect_ws(mgr, ev_handler_1, "wss://echo.websocket.org", NULL,
-                      NULL);
-  nc3 = mg_connect_ws(mgr, ev_handler_1, "ws://api.cesanta.com",

----
-
-Checks whether an http request is authorized. `domain` is the authentication

----
-
-Attaches a built-in HTTP event handler to the given connection.
-The 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_REPLY: The HTTP reply has arrived. The parsed HTTP reply is
-  passed as `struct http_message` through the handler's `void *ev_data`
-  pointer.
-- MG_EV_HTTP_CHUNK: The HTTP chunked-encoding chunk has arrived.
-  The 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 that arrives, and it can
-  potentially 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 the WebSocket
-  handshake request. `ev_data` contains parsed HTTP request.
-- MG_EV_WEBSOCKET_HANDSHAKE_DONE: server has completed the WebSocket
-  handshake. `ev_data` is `NULL`.
-- MG_EV_WEBSOCKET_FRAME: new WebSocket frame has arrived. `ev_data` is
-  `struct websocket_message *`
-
-When compiled with MG_ENABLE_HTTP_STREAMING_MULTIPART, Mongoose parses
-multipart requests and splits them into separate events:
-- MG_EV_HTTP_MULTIPART_REQUEST: Start of the request.
-  This event is sent before body is parsed. After this, the user
-  should expect a sequence of PART_BEGIN/DATA/END requests.
-  This is also the last time when headers and other request fields are
-  accessible.
-- MG_EV_HTTP_PART_BEGIN: Start of a part of a multipart message.
-  Argument: mg_http_multipart_part with var_name and file_name set
-  (if present). No data is passed in this message.
-- MG_EV_HTTP_PART_DATA: new portion of data from the multipart message.
-  Argument: mg_http_multipart_part. var_name and file_name are preserved,
-  data is available in mg_http_multipart_part.data.
-- MG_EV_HTTP_PART_END: End of the current part. var_name, file_name are
-  the same, no data in the message. If status is 0, then the part is
-  properly terminated with a boundary, status < 0 means that connection
-  was terminated.
-- MG_EV_HTTP_MULTIPART_REQUEST_END: End of the multipart request.
-  Argument: mg_http_multipart_part, var_name and file_name are NULL,
-  status = 0 means request was properly closed, < 0 means connection
-  was terminated (note: in this case both PART_END and REQUEST_END are
-  delivered).

----
-
-Helper function that creates an outbound HTTP connection.
-
-`url` is the URL to fetch. It must be properly URL-encoded, e.g. have
-no spaces, etc. By default, `mg_connect_http()` sends the Connection and
-Host headers. `extra_headers` is an extra HTTP header to send, e.g.
-`"User-Agent: my-app\r\n"`.
-If `post_data` is NULL, then a GET request is created. Otherwise, a POST
-request 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).
-
-Examples:
-
-```c
-  nc1 = mg_connect_http(mgr, ev_handler_1, "http://www.google.com", NULL,
-                        NULL);
-  nc2 = mg_connect_http(mgr, ev_handler_1, "https://github.com", NULL, NULL);
-  nc3 = mg_connect_http(
-      mgr, ev_handler_1, "my_server:8000/form_submit/",
-      "Content-Type: application/x-www-form-urlencoded\r\n",

-File upload handler.
-This handler can be used to implement file uploads with minimum code.
-This handler will process MG_EV_HTTP_PART_* events and store file data into
-a local file.
-`local_name_fn` will be invoked with whatever name was provided by the client
-and will expect the name of the local file to open. A return value of NULL
-will abort file upload (client will get a "403 Forbidden" response). If
-non-null, the returned string must be heap-allocated and will be freed by
-the caller.
-Exception: it is ok to return the same string verbatim.

-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`. Note `extra_headers`
-must NOT be terminated by a new line.

-symbol_kind: "func"
-signature: |
-  void mg_send_http_chunk(struct mg_connection *nc, const char *buf, size_t len);
----
-
-Sends buffer `buf` of size `len` to the client using chunked HTTP encoding.
-This function sends the buffer size as hex number + newline first, then
-the buffer itself, then the newline. For example,
-`mg_send_http_chunk(nc, "foo", 3)` will append the `3\r\nfoo\r\n` string
-to the `nc->send_mbuf` output IO buffer.
-
-NOTE: The HTTP header "Transfer-Encoding: chunked" should be sent prior to
-using this function.
-
-NOTE: do not forget to send an 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

-     * All files that match ssi_pattern are treated as SSI.

-     * Server Side Includes (SSI) is a simple interpreted server-side scripting
-     * language which is most commonly used to include the contents of a file
-     * into a web page. It can be useful when it is desirable to include a common
-     * piece of code throughout a website, for example, headers and footers.
-     *
-     * In order for a webpage to recognize an SSI-enabled HTML file, the
-     * filename should end with a special extension, by default the extension
-     * should be either .shtml or .shtm
-     *
-     * Unknown SSI directives are silently ignored by Mongoose. Currently,
-     * the following SSI directives are supported:
-     *    <!--#include FILE_TO_INCLUDE -->
-     *    <!--#exec "COMMAND_TO_EXECUTE" -->
-     *    <!--#call COMMAND -->
-     *
-     * Note that <!--#include ...> directive supports three path
-     *specifications:
-     *
-     * <!--#include virtual="path" -->  Path is relative to web server root
-     * <!--#include abspath="path" -->  Path is absolute or relative to the
-     *                                  web server working dir
-     * <!--#include file="path" -->,    Path is relative to current document
-     * <!--#include "path" -->
-     *
-     * The include directive may be used to include the contents of a file or
-     * the result of running a CGI script.
-     *
-     * The exec directive is used to execute
-     * a command on a server, and show command's output. Example:
-     *
-     * <!--#exec "ls -l" -->
-     *
-     * The call directive is a way to invoke a C handler from the HTML page.
-     * On each occurence of <!--#call COMMAND OPTIONAL_PARAMS> directive,
-     * Mongoose calls a registered event handler with MG_EV_SSI_CALL event,
-     * and event parameter will point to the COMMAND OPTIONAL_PARAMS string.
-     * An event handler can output any text, for example by calling
-     * `mg_printf()`. This is a flexible way of generating a web page on
-     * server side by calling a C event handler. Example:
-     *
-     * <!--#call foo --> ... <!--#call bar -->
-     *
-     * In the event handler:
-     *    case MG_EV_SSI_CALL: {
-     *      const char *param = (const char *) ev_data;
-     *      if (strcmp(param, "foo") == 0) {
-     *        mg_printf(c, "hello from foo");
-     *      } else if (strcmp(param, "bar") == 0) {
-     *        mg_printf(c, "hello from bar");
