docs: make each libcurl man specify protocol(s)

The mandatory header now has a mandatory list of protocols for which the
manpage is relevant.

Most man pages already has a "PROTOCOLS" section, but this introduces a
stricter way to specify the relevant protocols.

cd2nroff verifies that at least one protocol is mentioned (which can be
`*`).

This information is not used just yet, but A) the PROTOCOLS section can
now instead get generated and get a unified wording across all manpages
and B) this allows us to more reliably filter/search for protocol
specific manpages/options.

Closes #13166

NAME

CURLINFO_COOKIELIST - get all known cookies

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_COOKIELIST,
                           struct curl_slist **cookies);

DESCRIPTION

Pass a pointer to a 'struct curl_slist *' to receive a linked-list of all cookies curl knows (expired ones, too). Do not forget to call curl_slist_free_all(3) on the list after it has been used. If there are no cookies (cookies for the handle have not been enabled or simply none have been received) the 'struct curl_slist *' is made a NULL pointer.

Since 7.43.0 cookies that were imported in the Set-Cookie format without a domain name are not exported by this option.

PROTOCOLS

HTTP(S)

EXAMPLE

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

    /* enable the cookie engine */
    curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "");

    res = curl_easy_perform(curl);

    if(!res) {
      /* extract all known cookies */
      struct curl_slist *cookies = NULL;
      res = curl_easy_getinfo(curl, CURLINFO_COOKIELIST, &cookies);
      if(!res && cookies) {
        /* a linked list of cookies in cookie file format */
        struct curl_slist *each = cookies;
        while(each) {
          printf("%s\n", each->data);
          each = each->next;
        }
        /* we must free these cookies when we are done */
        curl_slist_free_all(cookies);
      }
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.14.1

RETURN VALUE

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