I believe there's a bug/usage issue in the websockets library
where during send(), EOF is detected and stored, but the receiving
thread is then discarding the last received frame. Avoid the bug
by replacing the close_socket() implementation of the websockets
library just for that test and leave detecting the EOF condition
to the receiving thread.
The terminate-while-queueing test added for #4428 failed spuriously
indicating that sometimes WebSocket clients receive code 1000 instead of 1001.
This happens if the ixwebsocket server is shutdown before the reply thread had a
chance to process queued close messages.
Fix by signaling and waiting for the dispatcher's reply thread to terminate
before returning from Terminate().
Terminate() is called when Zeek shuts down. If WebSocket client threads
were blocked in QueueForProcessing() due to reaching queue limits, these
previously would not exit QueueForProcessing() and instead block
indefinitely, resulting in the ixwebsocket library blocking and its
garbage collection thread running at 100%. Not great.
Closing the onloop instance will unblock the WebSocket client threads
for a timely shutdown.
Closes#4420

Add commands to the static methods for the Redis implementation
Redis: Check server version when connecting
Ensure the client side also uses the initial destination connection ID
for decryption purposes instead of the one from the current long header
packet. PCAP from local WiFi hotspot.
Instead of sending the accumulated CRYPTO frames after processing an
INITIAL packet, add logic to determine the total length of the TLS
Client or Server Hello (by peeking into the first 4 byte). Once all
CRYPTO frames have arrived, flush the reassembled data to the TLS
analyzer at once.
The payload is already consumed within the InitialPacket unit. Consuming
it again resulted in UDP datagrams with multiple packets to ignore
the remaining packets in the same UDP datagram. The baseline changes
showing I being followed by a new H indicates that the INITIAL packet
was followed by a HANDSHAKE packet, but previously Zeek discarded
these.

Vern didn't have ZeroMQ installed and the test was skipped for him.
Generally would recommend anyone working on core Zeek to install
libzmq-dev or the equivalent for their environment, but until it is a
real required dependency, loosen the requirements on the test.

Instead of simply removing holes from vectors or lists when converting
from Val to Broker format, error out as the receiver has no chance to
reconstruct where the hole might have been.
We could encode holes with broker::none, but this will put unnecessary
burden on language bindings and users due to the potential optionality.
Think a std::vector<uint64_t> that technically needs to be a
std::vector<std::optional<uint64_t>> to represent optional elements
properly.

Coverity complains proc is set under a lock, but accessed in Process()
without a lock. Fix this by setting it in Close() also without locking.
The proc member should only ever be accessed my the main thread.
