curldown: make 'added-in:' a mandatory header field
- generate AVAILABILITY manpage sections automatically - for consistent
  wording

- allows us to double-check against other documumentation (symbols-in-versions
  etc)

- enables proper automation/scripting based on this data

- lots of them were wrong or missing in the manpages

- several of them repeated (sometimes mismatching) backend support info

Add test 1488 to verify "added-in" version numbers against
symbols-in-versions.

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);
  }
}

RETURN VALUE

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