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

CURLINFO_RTSP_SERVER_CSEQ - get the next RTSP server CSeq

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_SERVER_CSEQ,
                           long *cseq);

DESCRIPTION

Pass a pointer to a long to receive the next CSeq that is expected to be used by the application.

Listening for server initiated requests is not implemented!

Applications wishing to resume an RTSP session on another connection should retrieve this info before closing the active connection.

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      long cseq;
      curl_easy_getinfo(curl, CURLINFO_RTSP_SERVER_CSEQ, &cseq);
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.20.0

RETURN VALUE

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