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
CURLOPT_WS_OPTIONS - WebSocket behavior options
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WS_OPTIONS, long bitmask);
~~~
# DESCRIPTION
Pass a long with a bitmask to tell libcurl about specific WebSocket
behaviors.
To detach a WebSocket connection and use the curl_ws_send(3) and
curl_ws_recv(3) functions after the HTTP upgrade procedure, set the
CURLOPT_CONNECT_ONLY(3) option to 2L.
Available bits in the bitmask
## CURLWS_RAW_MODE (1)
Deliver "raw" WebSocket traffic to the CURLOPT_WRITEFUNCTION(3)
callback.
In raw mode, libcurl does not handle pings or any other frame for the
application.
# DEFAULT
0
# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ws://example.com/");
/* tell curl we deal with all the WebSocket magic ourselves */
curl_easy_setopt(curl, CURLOPT_WS_OPTIONS, (long)CURLWS_RAW_MODE);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
~~~
# AVAILABILITY
