This continues to asserts the known version while decoding.  The client
will only ever generate the latest version while encoding and if the
response needs to change, the impetus will be a new feature, set in the
deserialized request, which can be used as a distinguisher.

Closes: #40104

And include iptproxy as a valid proxy type.

A follow-up wants to pass in a new property from the ClientConfig but it
would be an API breaking change to NewBrokerChannel.

However, it's unclear why NewBrokerChannel is exported at all.  No other
package in the repo depends on it and the known users of the library
probably wouldn't be construct them.

While this patch was being reviewed, a new constructor was added,
NewBrokerChannelWithUTLSSettings, with effectively the same issue.
Both of those exported ones are deleted here.

Instead of IPC.ClientOffers.  This makes things consistent with
EncodeClientPollRequest which adds the version while serializing.

The `generate_tarball` job vendors all Go modules to make packaging for
distributions easier.

Initialize eventsLogger for WebRTCPeer in client library test.

Let's reserve Tor error logs for more severe events that indicate
a client-side bug or absolute failure. By default, tor logs at severity
level notice (and above).

This change adds two new connection failure events for snowflake
proxies. One fires when the datachannel times out and another fires when
the connection to the proxy goes stale.

Fixes a bug where an uninitialized channel causes a panic when closed
(#40099).

Due to a bug (#40098), legacy oneshot connections have not worked for
awhile. Connections without the turbotunnel token would cause the server
to crash. This fixes that bug by removing support altogether and simply
closes the connection.
