bump(github.com/golang/glog): d1c4472bf2efd3826f2b5bdcc02d8416798d678c
Switch to glog for logging, bridge logging to glog.

1) imported glog to third_party (previous commit)
2) add support for third_party/update.sh to update just one pkg
3) search-and-replace:
  s/log.Printf/glog.Infof/
  s/log.Print/glog.Info/
  s/log.Fatalf/glog.Fatalf/
  s/log.Fatal/glog.Fatal/
4) convert glog.Info.*, err into glog.Error*

Adds some util interfaces to logging and calls them from each cmd, which
will set the default log output to write to glog.  Pass glog-wrapped
Loggers to etcd for logging.

Log files will go to /tmp - we should probably follow this up with a
default log dir for each cmd.

The glog lib is sort of weak in that it only flushes every 30 seconds, so
we spin up our own flushing goroutine.

Use glog for logging
Default --logtostderr=true

This retains compatibility with existing logging to stderr, until we can agree
on log dirs for each cmd.

Less verbose logging for "normal" things.

Don't log things that we expect to happen every sync loop, unless the user
asks for --v > 0.
