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.

Implement snowflake client lib as PTv2.1 Go API
...
This implements a pluggable transports v2.1 compatible Go API in the
Snowflake client library, and refactors how the main Snowflake program
calls it. The Go API implements the two required client side functions:
a constructor that returns a Transport, and a Dial function for the
Transport that returns a net.Conn. See the PT specification for more
information:
https://github.com/Pluggable-Transports/Pluggable-Transports-spec/blob/master/releases/PTSpecV2.1/Pluggable%20Transport%20Specification%20v2.1%20-%20Go%20Transport%20API.pdf

This update required two main changes to how we use the library. First,
we had to make sure we created the datachannel on the offering peer side
before creating the offer. Second, we had to make sure we wait for the
gathering of all candidates to complete since trickle-ice is enabled by
default. See the release notes for more details:

Send shutdown signal to shutdown open connections

Normally all dangling goroutines are terminated when the main function
exits. However, for projects that use a patched version of snowflake as
a library, these goroutines continued running as long as the main function
had not yet terminated. This commit has all open SOCKS connections close
after receiving a shutdown signal.

Implement NAT discovery (RFC 5780) at the client

Snowflake clients will now attempt NAT discovery using the provided STUN
servers and report their NAT type to the Snowflake broker for matching.
The three possibilities for NAT types are:
- unknown (the client was unable to determine their NAT type),
- restricted (the client has a restrictive NAT and can only be paired
with unrestricted NATs)
- unrestricted (the client can be paired with any other NAT).
