signal more consistent and legible.

Remove an erroneous debug statement.
Slightly friendlier pre-commit errors.

Make the pre-commit check spit out cut-and-paste commands and be more
obvious about errors.  Tested by making an invalid change and observing the
message generated.
Fixed the boilerplate hook to work on OS X, where apparently wc add's spaces

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

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*

Sadly, we have to keep passing etcd a log.Logger - it is not defined as an
interface so glog can not implement it.  Sigh.  Maybe we can convince etcd
code to define a minimal interface that both log.Logger and glog can
implement.  That's for another day.
