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.

NAME

CURLINFO_SSL_VERIFYRESULT - get the result of the certificate verification

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_VERIFYRESULT,
                           long *result);

DESCRIPTION

Pass a pointer to a long to receive the result of the server SSL certificate verification that was requested (using the CURLOPT_SSL_VERIFYPEER(3) option).

0 is a positive result. Non-zero is an error.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    long verifyresult;

    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

    res = curl_easy_perform(curl);
    if(res) {
      printf("error: %s\n", curl_easy_strerror(res));
      curl_easy_cleanup(curl);
      return 1;
    }

    res = curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT,
                            &verifyresult);
    if(!res) {
      printf("The peer verification said %s\n",
             (verifyresult ? "bad" : "fine"));
    }
    curl_easy_cleanup(curl);
  }
}

RETURN VALUE

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