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

curl_url_dup - duplicate a URL handle

SYNOPSIS

#include <curl/curl.h>

CURLU *curl_url_dup(const CURLU *inhandle);

DESCRIPTION

Duplicates the URL object the input CURLU inhandle identifies and returns a pointer to the copy as a new CURLU handle. The new handle also needs to be freed with curl_url_cleanup(3).

EXAMPLE

int main(void)
{
  CURLUcode rc;
  CURLU *url = curl_url();
  CURLU *url2;
  rc = curl_url_set(url, CURLUPART_URL, "https://example.com", 0);
  if(!rc) {
    url2 = curl_url_dup(url); /* clone it! */
    curl_url_cleanup(url2);
  }
  curl_url_cleanup(url);
}

AVAILABILITY

Added in 7.62.0

RETURN VALUE

Returns a new handle or NULL if out of memory.
