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_HSTSWRITEDATA - pointer passed to the HSTS write callback

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);

DESCRIPTION

Data pointer to pass to the HSTS write function. If you use the CURLOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you get as input in the fourth argument to the callback.

This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3) to do that.

DEFAULT

NULL

EXAMPLE

struct MyData {
  void *custom;
};

int main(void)
{
  CURL *curl = curl_easy_init();
  struct MyData this;
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

    /* pass pointer that gets passed in to the
       CURLOPT_HSTSWRITEFUNCTION callback */
    curl_easy_setopt(curl, CURLOPT_HSTSWRITEDATA, &this);

    curl_easy_perform(curl);
  }
}

RETURN VALUE

This returns CURLE_OK.
