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_HAPROXY_CLIENT_IP - set HAProxy PROXY protocol client IP

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXY_CLIENT_IP,
                          char *client_ip);

DESCRIPTION

When this parameter is set to a valid IPv4 or IPv6 numerical address, the library sends this address as client address in the HAProxy PROXY protocol v1 header at beginning of the connection.

This option is an alternative to CURLOPT_HAPROXYPROTOCOL(3) as that one cannot use a specified address.

DEFAULT

NULL, no HAProxy header is sent

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_HAPROXY_CLIENT_IP, "1.1.1.1");
    ret = curl_easy_perform(curl);
  }
}

RETURN VALUE

Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
