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.

# NAME
curl_multi_cleanup - close down a multi session
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLMcode curl_multi_cleanup(CURLM *multi_handle);
~~~
# DESCRIPTION
Cleans up and removes a whole multi stack. It does not free or touch any
individual easy handles in any way - they still need to be closed
individually, using the usual curl_easy_cleanup(3) way. The order of
cleaning up should be:
1 - curl_multi_remove_handle(3) before any easy handles are cleaned up
2 - curl_easy_cleanup(3) can now be called independently since the easy
handle is no longer connected to the multi handle
3 - curl_multi_cleanup(3) should be called when all easy handles are
removed
Passing in a NULL pointer in *multi_handle* makes this function return
CURLM_BAD_HANDLE immediately with no other action.
# EXAMPLE
~~~c
int main(void)
{
CURLM *multi = curl_multi_init();
/* when the multi transfer is done ... */
/* remove all easy handles, then: */
curl_multi_cleanup(multi);
}
~~~
# AVAILABILITY
Added in 7.9.6
# RETURN VALUE
CURLMcode type, general libcurl multi interface error code. On success,
CURLM_OK is returned.
