2e9e807178 Remove unecessary log messages 
Ever since we started scrubbing log messages, with the help of regexes
for https://bugs.torproject.org/21304 logging has become more CPU
intensive due to our use of regular expressions.

Logging the byte count of every incoming and outgoing message at the
proxy-go instances was taking up a lot of CPU and contrubuting to the
high CPU usage seen in https://bugs.torproject.org/33211.

c2a12c25d1 Update appengine for the Go 1.11 runtime. 
https://cloud.google.com/appengine/docs/standard/go111/go-differences
This is untested, because I wasn't actually able to deploy without
enabling Cloud Build and setting up a billing account.

c124e8c643 In server, treat a client IP address of 0.0.0.0 as missing. 
Some proxies currently send ?client_ip=0.0.0.0 because of an error in
how they attempt to grep the address from the client's SDP. That's
inflating our "%d/%d connections had client_ip" logs. Instead, treat
these cases as if the IP address were absent.

380b133155 Close internal Pipes in websocketconn.Conn Close. 
Unless something externally called Write after Close, the
writeLoop(ws, pr2) goroutine would run forever, because nothing would
ever close pw2/pr2.

256959ca65 Implement net.Conn for websocketconn.Conn. 
We had already implemented Read, Write, and Close. Pass RemoteAddr,
LocalAddr, SetReadDeadline, and SetWriteDeadline through to the
underlying *websocket.Conn. Implement SetDeadline by calling both
SetReadDeadline and SetWriteDeadline.

50673d4943 Remove client test with nil broker 
We are no longer checking for nil BrokerChannels in Catch because this
case is caught from the return values of NewBrokerChannel. This change
caused a no longer necessary unit test to hang.

bc5498cb4b Fix the order of arguments of client copyLoop to match the call. 
The call was
	copyLoop(socks, snowflake)
but the function signature was
	func copyLoop(WebRTC, SOCKS io.ReadWriter) {

The mistake was mostly harmless, because both arguments were treated the
same, except that error logs would have reported the wrong direction.

2fb52c8639 Check for an invalid broker URL at a higher level. 
Instead of returning nil from NewBrokerChannel and having
WebRTCDialer.Catch check for nil, let NewBrokerChannel return an error
and bail out before calling WebRTCDialer.Catch.

Suggested by cohosh.
