curldown: make 'added-in:' a mandatory header field

- generate AVAILABILITY manpage sections automatically - for consistent
  wording

- allows us to double-check against other documumentation (symbols-in-versions
  etc)

- enables proper automation/scripting based on this data

- lots of them were wrong or missing in the manpages

- several of them repeated (sometimes mismatching) backend support info

Add test 1488 to verify "added-in" version numbers against
symbols-in-versions.

Closes #14217

NAME

CURLOPT_WS_OPTIONS - WebSocket behavior options

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WS_OPTIONS, long bitmask);

DESCRIPTION

Pass a long with a bitmask to tell libcurl about specific WebSocket behaviors.

To detach a WebSocket connection and use the curl_ws_send(3) and curl_ws_recv(3) functions after the HTTP upgrade procedure, set the CURLOPT_CONNECT_ONLY(3) option to 2L.

Available bits in the bitmask

CURLWS_RAW_MODE (1)

Deliver "raw" WebSocket traffic to the CURLOPT_WRITEFUNCTION(3) callback.

In raw mode, libcurl does not handle pings or any other frame for the application.

DEFAULT

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "ws://example.com/");
    /* tell curl we deal with all the WebSocket magic ourselves */
    curl_easy_setopt(curl, CURLOPT_WS_OPTIONS, (long)CURLWS_RAW_MODE);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
