Add a test/example forwarding all new_connection() events produced during
`zeek -r wikipedia.trace` as my_new_connection() to a WebSocket client.
This is mostly to demonstrate and verify usage of suspend_processing(),
websocket_client_added(), resume_processing(), Pcap::file_done(),
websocket_client_lost() and terminate() together.
The upstream recently merge Christian's fixes for the fd_map allocations
so that patch doesn't need to be in our fork anymore. I also tested removing
the patch about timers from our fork, and it seems to only matter for Linux
kernels earlier than 5.3. All of our supported platforms are newer than
that.

Add full support for RFC 9460's SvcParams list.
Amend the existing `dns_svcb_rr` record by a vector of new
`dns_svcb_param` records containing aptly typed SvcParamKey and
SvcParamValue pairs. Example output:
```
@load base/protocols/dns
event dns_HTTPS( c: connection , msg: dns_msg , ans: dns_answer , https: dns_svcb_rr ) {
for (_, param in https$svc_params)
print to_json(param); # filter uninitialised values
}
```
