Use %w, not %v, in fmt.Errorf, so errors can be unwrapped.

Have encapsulation.ReadData return an error when the buffer is short.
...
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/154#note_2919109
Still ignoring the io.ErrShortBuffer at the callers, which retains
current behavior.

Have SnowflakeClientConn implement io.WriterTo.
...
By forwarding the method to the inner smux.Stream. This is to prevent
io.Copy in the top-level proxy function from allocating a buffer per
client.
The smux.Stream WriteTo method returns io.EOF on success, contrary to
the contract of io.Copy that says it should return nil. Ignore io.EOF in
the proxy loop to avoid a log message.

Remove support for oneshot mode
...
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.
