  // BeforeUnload interception ////////////////////////////////////////////////

  // In order to preserve any edits the user may have made in devtools, the
  // beforeunload event of the inspected page is hooked - devtools gets the
  // first shot at handling beforeunload and presents a dialog to the user. If
  // the user accepts the dialog then the script is given a chance to handle
  // it. This way 2 dialogs may be displayed: one from the devtools asking the
  // user to confirm that they're ok with their devtools edits going away and
  // another from the webpage as the result of its beforeunload handler.
  // The following set of methods handle beforeunload event flow through
  // devtools window. When the |contents| with devtools opened on them are
  // getting closed, the following sequence of calls takes place:
  // 1. |DevToolsWindow::InterceptPageBeforeUnload| is called and indicates
  //    whether devtools intercept the beforeunload event.
  //    If InterceptPageBeforeUnload() returns true then the following steps
  //    will take place; otherwise only step 4 will be reached and none of the
  //    corresponding functions in steps 2 & 3 will get called.
  // 2. |DevToolsWindow::InterceptPageBeforeUnload| fires beforeunload event
  //    for devtools frontend, which will asynchronously call
  //    |WebContentsDelegate::BeforeUnloadFired| method.
  //    In case of docked devtools window, devtools are set as a delegate for
  //    its frontend, so method |DevToolsWindow::BeforeUnloadFired| will be
  //    called directly.
  //    If devtools window is undocked it's not set as the delegate so the call
  //    to BeforeUnloadFired is proxied through HandleBeforeUnload() rather
  //    than getting called directly.
  // 3a. If |DevToolsWindow::BeforeUnloadFired| is called with |proceed|=false
  //     it calls through to the content's BeforeUnloadFired(), which from the
  //     WebContents perspective looks the same as the |content|'s own
  //     beforeunload dialog having had it's 'stay on this page' button clicked.
  // 3b. If |proceed| = true, then it fires beforeunload event on |contents|
  //     and everything proceeds as it normally would without the Devtools
  //     interception.
  // 4. If the user cancels the dialog put up by either the WebContents or
  //    devtools frontend, then |contents|'s |BeforeUnloadFired| callback is
  //    called with the proceed argument set to false, this causes
  //    |DevToolsWindow::OnPageCloseCancelled| to be called.

  // Devtools window in undocked state is not set as a delegate of
  // its frontend. Instead, an instance of browser is set as the delegate, and
  // thus beforeunload event callback from devtools frontend is not delivered
  // to the instance of devtools window, which is solely responsible for
  // managing custom beforeunload event flow.
  // This is a helper method to route callback from
  // |Browser::BeforeUnloadFired| back to |DevToolsWindow::BeforeUnloadFired|.
  // * |proceed| - true if the user clicked 'ok' in the beforeunload dialog,
  //   false otherwise.
  // * |proceed_to_fire_unload| - output parameter, whether we should continue
  //   to fire the unload event or stop things here.
  // Returns true if devtools window is in a state of intercepting beforeunload
  // event and if it will manage unload process on its own.
