- 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

Closes #14227

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {

    curl_easy_setopt(curl, CURLOPT_SSL_EC_CURVES, "X25519:P-521");
