move these constants to anonymous namespace

[alexeypa (please no reviews), 2013/04/06 18:07:56]

Constants have local scope by default. There is not need to place them into a
anonymous namespace. We use the same approach in other files too.

+
+// Minutes before the session will be disconnected (from the moment the Continue
+// window has been shown).
+const int kSessionDisconnectTimeoutMinutes = 1;
+
+namespace remoting {
+
+ContinueWindow::~ContinueWindow() {
+  DCHECK(CalledOnValidThread());

[Sergey Ulanov, 2013/04/04 21:04:26]

NonThreadSafe destructor has the same DCHECK, no need to duplicate it here.

[alexeypa (please no reviews), 2013/04/06 18:07:56]

Done.

Maybe OnDisconnectTimer()?

[alexeypa (please no reviews), 2013/04/06 18:07:56]

The primary purpose if this API is to be called by platform-specific
implementations of the continue window. Hence the name. 

PS. It has to be public, because on Mac the caller is not derived from
ContinueWindow.
