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_PROXYHEADER - set of HTTP headers to pass to proxy

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYHEADER,
                          struct curl_slist *headers);

DESCRIPTION

Pass a pointer to a linked list of HTTP headers to pass in your HTTP request sent to a proxy. The rules for this list is identical to the CURLOPT_HTTPHEADER(3) option's.

The headers set with this option is only ever used in requests sent to a proxy

when there is also a request sent to a host.

The first line in a request (containing the method, usually a GET or POST) is NOT a header and cannot be replaced using this option. Only the lines following the request-line are headers. Adding this method line in this list of headers causes your request to send an invalid header.

Pass a NULL to this to reset back to no custom headers.

DEFAULT

NULL

EXAMPLE

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

  struct curl_slist *list;

  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    curl_easy_setopt(curl, CURLOPT_PROXY, "http://proxy.example.com:80");

    list = curl_slist_append(NULL, "Shoesize: 10");
    list = curl_slist_append(list, "Accept:");

    curl_easy_setopt(curl, CURLOPT_PROXYHEADER, list);

    curl_easy_perform(curl);

    curl_slist_free_all(list); /* free the list again */
  }
}

AVAILABILITY

Added in 7.37.0

RETURN VALUE

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