Move message routing from CefBrowser to CefFrame (see issue #2498). This change moves the SendProcessMessage method from CefBrowser to CefFrame and adds CefBrowser parameters to OnProcessMessageReceived and OnDraggableRegionsChanged. The internal implementation has changed as follows: - Frame IDs are now a 64-bit combination of the 32-bit render_process_id and render_routing_id values that uniquely identify a RenderFrameHost (RFH). - CefFrameHostImpl objects are now managed by CefBrowserInfo with life span tied to RFH expectations. Specifically, a CefFrameHostImpl object representing a sub-frame will be created when a RenderFrame is created in the renderer process and detached when the associated RenderFrame is deleted or the renderer process in which it runs has died. - The CefFrameHostImpl object representing the main frame will always be valid but the underlying RFH (and associated frame ID) may change over time as a result of cross-origin navigations. Despite these changes calling LoadURL on the main frame object in the browser process will always navigate as expected. - Speculative RFHs, which may be created as a result of a cross-origin navigation and discarded if that navigation is not committed, are now handled correctly (e.g. ignored in most cases until they're committed). - It is less likely, but still possible, to receive a CefFrame object with an invalid frame ID (ID < 0). This can happen in cases where a RFH has not yet been created for a sub-frame. For example, when OnBeforeBrowse is called before initiating navigation in a previously nonexisting sub-frame. To test: All tests pass with NetworkService enabled and disabled.

Create a ChromeBrowserHostImpl for every Chrome tab (see issue #2969) The Browser object represents the top-level Chrome browser window. One or more tabs (WebContents) are then owned by the Browser object via TabStripModel. A new Browser object can be created programmatically using "new Browser" or Browser::Create, or as a result of user action such as dragging a tab out of an existing window. New or existing tabs can also be added to an already existing Browser object. The Browser object acts as the WebContentsDelegate for all attached tabs. CEF integration requires WebContentsDelegate callbacks and notification of tab attach/detach. To support this integration we add a cef::BrowserDelegate (ChromeBrowserDelegate) member that is created in the Browser constructor and receives delegation for the Browser callbacks. ChromeBrowserDelegate creates a new ChromeBrowserHostImpl when a tab is added to a Browser for the first time, and that ChromeBrowserHostImpl continues to exist until the tab's WebContents is destroyed. The associated WebContents object does not change, but the Browser object will change when the tab is dragged between windows. CEF callback logic is shared between the chrome and alloy runtimes where possible. This shared logic has been extracted from CefBrowserHostImpl to create new CefBrowserHostBase and CefBrowserContentsDelegate classes. The CefBrowserHostImpl class is now only used with the alloy runtime and will be renamed to AlloyBrowserHostImpl in a future commit.

Fix draggable region update with BackForwardCache enabled (see issue #2421) When BackForwardCache is enabled and the user navigates the main frame back/forward a new RFH may be created for an existing main frame GlobalId value and CefFrameHostImpl (e.g. an object that was previously Detach()ed after main frame navigation called SetMainFrame, but for which RenderFrameDeleted was not subsequently called due to insertion in the BackForwardCache). In this case we can re-attach the new RFH to the existing main frame CefFrameHostImpl in RenderFrameHostStateChanged and resume processing of messages. Swapping back/forward to an existing (already loaded) renderer does not trigger new notifications for draggable regions (e.g. RenderFrameObserver:: DraggableRegionsChanged is not called by default). We therefore explicitly request an update of draggable regions by sending the DidStopLoading message to the renderer. A new |reattached| parameter is added to CefFrameHandler::OnFrameAttached to support identification of BackForwardCache usage by the client. To test with unit tests: Run `ceftests --gtest_filter=DraggableRegionsTest.DraggableRegionsCrossOrigin --enable-features=BackForwardCache` To test manually: 1. Run `cefclient --enable-features=BackForwardCache --use-views --url=http://tests/draggable`, note that draggable regions work. 2. Load https://www.google.com via the address bar, note that draggable regions are removed. 3. Go back to http://tests/draggable, note that draggable regions work. 4. Go forward to https://www.google.com, note that draggable regions are removed.

This can happen in cases where a RFH has not yet been created for a sub-frame. For example, when OnBeforeBrowse is called before initiating navigation in a previously nonexisting sub-frame. To test: All tests pass with NetworkService enabled and disabled.

Create a ChromeBrowserHostImpl for every Chrome tab (see issue #2969) The Browser object represents the top-level Chrome browser window. One or more tabs (WebContents) are then owned by the Browser object via TabStripModel. A new Browser object can be created programmatically using "new Browser" or Browser::Create, or as a result of user action such as dragging a tab out of an existing window. New or existing tabs can also be added to an already existing Browser object. The Browser object acts as the WebContentsDelegate for all attached tabs. CEF integration requires WebContentsDelegate callbacks and notification of tab attach/detach. To support this integration we add a cef::BrowserDelegate (ChromeBrowserDelegate) member that is created in the Browser constructor and receives delegation for the Browser callbacks. ChromeBrowserDelegate creates a new ChromeBrowserHostImpl when a tab is added to a Browser for the first time, and that ChromeBrowserHostImpl continues to exist until the tab's WebContents is destroyed. The associated WebContents object does not change, but the Browser object will change when the tab is dragged between windows. CEF callback logic is shared between the chrome and alloy runtimes where possible. This shared logic has been extracted from CefBrowserHostImpl to create new CefBrowserHostBase and CefBrowserContentsDelegate classes. The CefBrowserHostImpl class is now only used with the alloy runtime and will be renamed to AlloyBrowserHostImpl in a future commit.

Move message routing from CefBrowser to CefFrame (see issue #2498). This change moves the SendProcessMessage method from CefBrowser to CefFrame and adds CefBrowser parameters to OnProcessMessageReceived and OnDraggableRegionsChanged. The internal implementation has changed as follows: - Frame IDs are now a 64-bit combination of the 32-bit render_process_id and render_routing_id values that uniquely identify a RenderFrameHost (RFH). - CefFrameHostImpl objects are now managed by CefBrowserInfo with life span tied to RFH expectations. Specifically, a CefFrameHostImpl object representing a sub-frame will be created when a RenderFrame is created in the renderer process and detached when the associated RenderFrame is deleted or the renderer process in which it runs has died. - The CefFrameHostImpl object representing the main frame will always be valid but the underlying RFH (and associated frame ID) may change over time as a result of cross-origin navigations. Despite these changes calling LoadURL on the main frame object in the browser process will always navigate as expected. - Speculative RFHs, which may be created as a result of a cross-origin navigation and discarded if that navigation is not committed, are now handled correctly (e.g. ignored in most cases until they're committed). - It is less likely, but still possible, to receive a CefFrame object with an invalid frame ID (ID < 0). This can happen in cases where a RFH has not yet been created for a sub-frame. For example, when OnBeforeBrowse is called before initiating navigation in a previously nonexisting sub-frame. To test: All tests pass with NetworkService enabled and disabled.

Fix draggable region update with BackForwardCache enabled (see issue #2421) When BackForwardCache is enabled and the user navigates the main frame back/forward a new RFH may be created for an existing main frame GlobalId value and CefFrameHostImpl (e.g. an object that was previously Detach()ed after main frame navigation called SetMainFrame, but for which RenderFrameDeleted was not subsequently called due to insertion in the BackForwardCache). In this case we can re-attach the new RFH to the existing main frame CefFrameHostImpl in RenderFrameHostStateChanged and resume processing of messages. Swapping back/forward to an existing (already loaded) renderer does not trigger new notifications for draggable regions (e.g. RenderFrameObserver:: DraggableRegionsChanged is not called by default). We therefore explicitly request an update of draggable regions by sending the DidStopLoading message to the renderer. A new |reattached| parameter is added to CefFrameHandler::OnFrameAttached to support identification of BackForwardCache usage by the client. To test with unit tests: Run `ceftests --gtest_filter=DraggableRegionsTest.DraggableRegionsCrossOrigin --enable-features=BackForwardCache` To test manually: 1. Run `cefclient --enable-features=BackForwardCache --use-views --url=http://tests/draggable`, note that draggable regions work. 2. Load https://www.google.com via the address bar, note that draggable regions are removed. 3. Go back to http://tests/draggable, note that draggable regions work. 4. Go forward to https://www.google.com, note that draggable regions are removed.
