docs/libcurl: generate PROTOCOLS from meta-data

Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.

It also generates TLS backend information for options marked for TLS as
protocol.

Closes #13175

NAME

CURLOPT_NOBODY - do the download request without getting the body

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOBODY, long opt);

DESCRIPTION

A long parameter set to 1 tells libcurl to not include the body-part in the output when doing what would otherwise be a download. For HTTP(S), this makes libcurl do a HEAD request. For most other protocols it means just not asking to transfer the body data.

For HTTP operations when CURLOPT_NOBODY(3) has been set, disabling this option (with 0) makes it a GET again - only if the method is still set to be HEAD. The proper way to get back to a GET request is to set CURLOPT_HTTPGET(3) and for other methods, use the POST or UPLOAD options.

Enabling CURLOPT_NOBODY(3) means asking for a download without a body.

If you do a transfer with HTTP that involves a method other than HEAD, you get a body (unless the resource and server sends a zero byte body for the specific URL you request).

DEFAULT

0, the body is transferred

EXAMPLE

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

    /* get us the resource without a body - use HEAD! */
    curl_easy_setopt(curl, CURLOPT_NOBODY, 1L);

    /* Perform the request */
    curl_easy_perform(curl);
  }
}

AVAILABILITY

RETURN VALUE

Returns CURLE_OK
