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.

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
}

Values with malformed data or belonging to invalid/reserved keys
are passed raw bytes in network order for script-level inspection.

Fix a few more random clang-tidy findings

We install test data which we also make available under an alternative
path for backwards compatibility. The installation of this symlink did
not take `DESTDIR` installs like used by Zeek's packaging into account
which caused installations from packages to behave different from
installs from source.
This patch fixes the symlink to respect a possible `DESTDIR`.
Closes#3266.
When a WebSocket client sends an event to Zeek without explicit network
timestamp metadata, Zeek would use -1.0 as a timestamp for any events
published while handling this event. Instead, it seems far more sensible
to use the current network time in that scenario.
Event when there's no metadata attached to an event, we'd still use the
constructor passing an empty metadata vector, resulting in an on-the-wire
representation with an empty trailing vector.
Particularly visible when just snooping events via websocat. There also
seems to be some bug with the timestamp -1 handling.
* 'master' of https://github.com/blightzero/zeek:
Changed behavior of var-extraction-uri.zeek from policy/protocol/http to extract only the URI parameter names. Do not include the path in the first parameter name. Only extract uri vars if parameters actually exist.
Previously, Zeek treated the receipt of `AuthenticationOk` as a
successful login. However, according to the PostgreSQL
Frontend/Backend Protocol, the startup phase is not complete until
the server sends `ReadyForQuery`. It is still possible for the server
to emit an `ErrorResponse` (e.g. ERRCODE_INVALID_AUTHORIZATION_SPECIFICATION)
after `AuthenticationOk` but before `ReadyForQuery`.
This change updates the PostgreSQL analyzer to defer reporting login
success until `ReadyForQuery` is observed. This prevents false
positives in cases where authentication succeeds but session startup
fails.
The previous approach ignored the fact that nested / inner values might
also be Broker::Data values. I'm not super sure about the validity of
the test, because it's essentially demonstrating any-nesting, but
it's not leading to extra Broker::Data encoding.
Parameters relied on is_record for a couple of validations, but they are
not records and should not be treated as such. This way we can validate
&optional better.
There was some confusing behavior with &optional and locals, so this
should get rid of that by making it an error. However, there is a case
where function parameters are still allowed to have &optional - this is
because there are checks for &default in parameters as well.
A user provided a SMB2 pcap with the reserved1 field of a ReadResponse
set to 1 instead of 0. This confused the padding computation due to
including this byte into the offset. Properly split data_offset and
reserved1 into individual byte fields.
Closes#4730
* origin/topic/timw/cleanup-warnings-from-plugin-btest-builds:
Update zeek-aux to remove BRO_DIST from plugin skeleton
cmake_minimum_required() should come before project()
This also changes the output of connection UIDs from the tap analyzer to be
prefixed with C for easier correlation with other logs.
Relates to #4337#4725#4734#4737
