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.

CefRenderFrameObserver::CefRenderFrameObserver(

Add chrome runtime support for more callbacks and ceftests (see issue #2969) This change adds support for: - Protocol and request handling. - Loading and navigation events. - Display and focus events. - Mouse/keyboard events. - Popup browsers. - Callbacks in the renderer process. - Misc. functionality required for ceftests. This change also adds a new CefBrowserProcessHandler::GetCookieableSchemes callback for configuring global state that will be applied to all CefCookieManagers by default. This global callback is currently required by the chrome runtime because the primary ProfileImpl is created via ChromeBrowserMainParts::PreMainMessageLoopRun (CreatePrimaryProfile) before OnContextCreated can be called. ProfileImpl will use the "C:\Users\[user]\AppData\Local\CEF\User Data\Default" directory by default (on Windows). Cookies may persist in this directory when running ceftests and may need to be manually deleted if those tests fail. Remaining work includes: - Support for client-created request contexts. - Embedding the browser in a Views hierarchy (cefclient support). - TryCloseBrowser and DoClose support. - Most of the CefSettings configuration. - DevTools protocol and window control (ShowDevTools, ExecuteDevToolsMethod). - CEF-specific WebUI pages (about, license, webui-hosts). - Context menu customization (CefContextMenuHandler). - Auto resize (SetAutoResizeEnabled). - Zoom settings (SetZoomLevel). - File dialog runner (RunFileDialog). - File and JS dialog handlers (CefDialogHandler, CefJSDialogHandler). - Extension loading (LoadExtension, etc). - Plugin loading (OnBeforePluginLoad). - Widevine loading (CefRegisterWidevineCdm). - PDF and print preview does not display. - Crash reporting is untested. - Mac: Web content loads but does not display. The following ceftests are now passing when run with the "--enable-chrome-runtime" command-line flag: CorsTest.* DisplayTest.*:-DisplayTest.AutoResize DOMTest.* DraggableRegionsTest.* ImageTest.* MessageRouterTest.* NavigationTest.* ParserTest.* RequestContextTest.*Global* RequestTest.* ResourceManagerTest.* ResourceRequestHandlerTest.* ResponseTest.* SchemeHandlerTest.* ServerTest.* StreamResourceHandlerTest.* StreamTest.* StringTest.* TaskTest.* TestServerTest.* ThreadTest.* URLRequestTest.*Global* V8Test.*:-V8Test.OnUncaughtExceptionDevTools ValuesTest.* WaitableEventTest.* XmlReaderTest.* ZipReaderTest.*

Add support for MimeHandlerViewInCrossProcessFrame (fixes issue #2727) The PDF loading documentation in extension_system.cc has be updated to describe the new code paths. To support delivery of input events to the mime handler renderer process it is now necessary to route events via the correct RWHV interface. For Aura-based platforms (Windows/Linux) this means RWHVAura::On*Event and for macOS this means RWHVMac::RouteOrProcess*Event. Since Aura uses UI event types these have become the source of truth on Aura-based platforms with conversion to Web event types when needed (primarily for OSR). This change also adds a timeout for CefProcessHostMsg_GetNewBrowserInfo to avoid a hung renderer process if the guest WebContents route is not registered via CefMimeHandlerViewGuestDelegate::OnGuestDetached as expected prior to CefBrowserInfoManager::OnGetNewBrowserInfo being called. This timeout can be disabled for testing purposes by passing the `--disable-new-browser-info-timeout` command-line flag. The `--disable-features=MimeHandlerViewInCrossProcessFrame` command-line flag can be used for a limited time to restore the previous implementation based on BrowserPlugin. That implementation will be deleted starting with the 3897 branch update. Known issues: - ExecuteJavaScript calls on the frame hosting the PDF extension will not be routed to the mime handler renderer process. - The PDF extension will not load successfully if blocked by ChromePluginPlaceholder and then manually continued via the "Run this plugin" context menu option (see https://crbug.com/533069#c41).

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.
