a554439370 Link to #26360 for why we blackhole logs without -log. 
Maybe we'll able to remove this in the far future.

6077141f4a Log to io.Discard if no log file is set. 
https://bugs.torproject.org/25600#comment:14

Snowflake in Tor Browser has been hanging after surfing for a while.
(Tor reports "no running bridges".) It only began happening after commit
12922a232b, which caused snowflake-client not to log to a file by
default (leaving it to log to its default stderr). What seems to be
happening is that tor doesn't read from its PT clients' stderr, leaving
a buffer to fill up that eventually causes a hang.

947636ae81 Change to standalone broker. 
https://snowflake-reg-test.appspot.com/ for the client (needs domain fronting)
https://snowflake-broker.bamsoftware.com/ for the proxies (no fronting)

Note that fronting to App Engine doesn't currently actually work because
of https://bugs.torproject.org/25804; this commit doesn't change that.

6a9c2bf951 Don't log "SOCKS accepted" if there was an Accept error. 
This actually caused a nil pointer dereference panic when Accept
returned an error, because conn was nil.

c61336c897 Use ResolveReference to construct the /client URL. 
This way works when the base URL lacks a path, e.g.
"http://127.0.0.1:8080".

bbb5a6aca2 webrtc.NewIceServer already does this split / validation 
It also expects to be called with a non-empty string, which isn't
the case with this Split which always envokes the loop at least
once.  If -ice was omitted, an error was logged.

0c02af35d0 Move handling of -ice option into main. 
Rather than having it happen as a side effect of flag parsing.

Having it happen as a side effect of flag parsing caused log messages
related to handling the option (e.g. "IceServerList:") to always go to
stderr, despite the presence of a -log option. This is because the
requested log file had not been opened yet.
