ca91b5eddd Reload authenticated-emails-file upon update
This change extracts the UserMap class from NewValidator() so that its
LoadAuthenticatedEmailsFile() method can be called concurrently. This method
is called by a goroutine containing a fsnotify.Watcher watching the
authenticated emails file.

Watching isn't forever aborted when the authenticated emails file disappears.
The goroutine will call os.Stat() up to twenty times a second if the file is
persistently missing, but that's the pathological case, not the common one.

The common case is that some editors (including Vim) will perform a
rename-and-replace when updating a file, triggering fsnotify.Rename events,
and the file will temporarily disappear. This watcher goroutine handles that
case.

Also, on some platforms (notably Arch Linux), a remove will be preceded by a
fsnotify.Chmod, causing a race between the upcoming fsnotify.Remove and the
call to UserMap.LoadAuthenticatedEmailsFile(). Hence, we treat fsnotify.Chmod
the same as fsnotify.Remove and fsnotify.Rename. There's no significant
penalty to re-adding a file to the watcher.

Also contains the following small changes from the summary of commits below:

- Minor optimization of email domain search
- Fixed api_test.go on Windows
- Add deferred File.Close() calls where needed
- Log error and return if emails file doesn't parse

37f287bef4 Calculate cookie expiration from encoded timestamp
Found out the hard way that _incoming_ cookies do _not_ have their expiration
timestamps encoded. To perform auto-refresh based on expiration time, we have
to recalculate it from the time encoded in the cookie value.

always redirect back to /oauth2/sign_in, essentially creating an infinite

9d8f932797 Extract api package
This is the first step towards genericizing the google_auth_proxy to support
OAuth2 providers other than Google as discussed in #65. The `api` package will
enable multiple providers to use the same `api.Request()` implementation.
