curldown: fixups
- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

# NAME
CURLOPT_HAPROXY_CLIENT_IP - set HAProxy PROXY protocol client IP
# SYNOPSIS
~~~c
#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
# %PROTOCOLS%
# EXAMPLE
~~~c
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);
}
}
~~~
# %AVAILABILITY%
# RETURN VALUE
Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
