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

curl_easy_strerror - return string describing error code

SYNOPSIS

#include <curl/curl.h>

const char *curl_easy_strerror(CURLcode errornum);

DESCRIPTION

The curl_easy_strerror(3) function returns a string describing the CURLcode error code passed in the argument errornum.

Typically applications also appreciate CURLOPT_ERRORBUFFER(3) for more specific error descriptions generated at runtime.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    /* set options */
    /* Perform the entire transfer */
    res = curl_easy_perform(curl);
    /* Check for errors */
    if(res != CURLE_OK)
      fprintf(stderr, "curl_easy_perform() failed: %s\n",
              curl_easy_strerror(res));
  }
}

RETURN VALUE

A pointer to a null-terminated string.
