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_DOH_SSL_VERIFYSTATUS - verify the DoH SSL certificate's status

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_SSL_VERIFYSTATUS,
                          long verify);

DESCRIPTION

Pass a long as parameter set to 1 to enable or 0 to disable.

This option determines whether libcurl verifies the status of the DoH (DNS-over-HTTPS) server cert using the "Certificate Status Request" TLS extension (aka. OCSP stapling).

This option is the DoH equivalent of CURLOPT_SSL_VERIFYSTATUS(3) and only affects requests to the DoH server.

If this option is enabled and the server does not support the TLS extension, the verification fails.

DEFAULT

EXAMPLE

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

    curl_easy_setopt(curl, CURLOPT_DOH_URL,
                     "https://cloudflare-dns.com/dns-query");

    /* Ask for OCSP stapling when verifying the DoH server */
    curl_easy_setopt(curl, CURLOPT_DOH_SSL_VERIFYSTATUS, 1L);

    curl_easy_perform(curl);
  }
}

AVAILABILITY

Added in 7.76.0.

RETURN VALUE

Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise returns CURLE_NOT_BUILT_IN.
