Maintain backward compatability with old clients
...
Introduce a new commandline and SOCKS argument for comma-separated
domain fronts rather than repurposing the old one so that we can
maintain backwards compatability with users running old versions of the
client. A new bridge line shared on circumvention settings could have
both the front= and fronts= options set.

Randomly select front domain from comma-separated list

This commmit changes the command-line and Bridge line arguments to take
a comma-separated list of front domains. The change is backwards
compatible with old Bridge and ClientTransportPlugin lines. At
rendezvous time, a front domain will be randomly chosen from the list.

Use Pion's Setting Engine to reduce Multicast DNS noise
...
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40123
The purpose of the patch is to prevent Pion from opening the mDNS port,
thus preventing snowflake from directly leaking .local candidates.
What this doesn't prevent is the resolution of .local candidates
once they are passed on to the system DNS.

Stop storing version in ClientPollRequest
...
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.

Introduce an unexported newBrokerChannelFromConfig
...
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.
