curldown: fixups
- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

Closes #14227

# NAME
CURLINFO_RTSP_SERVER_CSEQ - get the next RTSP server CSeq
# SYNOPSIS
~~~c
#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.
# %PROTOCOLS%
# EXAMPLE
~~~c
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%
# RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
