Marshall Greenblatt 7a4669ad49 chrome: Standardize fullscreen transition behavor/callbacks (fixes #3571)
Use the same code path for all fullscreen transitions so that Chrome UI updates
correctly. All user-initiated fullscreen transitions now result in
CefWindowDelegate::OnWindowFullscreenTransition callbacks.

Marshall Greenblatt 0b99f92e97 views: Add support for modal browser dialogs
A modal dialog is a child CefWindow that implements some special behaviors
relative to a parent CefWindow. Like any CefWindow it can be framed with
titlebar or frameless, and optionally contain draggable regions (subject to
platform limitations described below). Modal dialogs are shown centered on
the parent window (inside a single display) and always stay on top of the
parent window in z-order. Sizing behavior and available window buttons are
controlled via the usual CefWindowDelegate callbacks. For example, the dialog
can have a preferred size with resize, minimize and maximize disabled (via
GetPreferredSize, CanResize, CanMinimize and CanMaximize respectively).

This change adds support for two modality modes. With window modality all
controls in the parent window are disabled. With browser modality only the
browser view in the parent window is disabled.

Both modality modes require that a valid parent window be returned via
GetParentWindow. For window modality return true from IsWindowModalDialog
and call CefWindow::Show. For browser modality return false from
IsWindowModalDialog (the default value) and call
CefWindow::ShowAsBrowserModalDialog with a reference to the parent window's
browser view.

Window modal dialog behavior depends on the platform. On Windows and
Linux these dialogs have a titlebar and can be moved independent of the
parent window. On macOS these dialogs do not have a titlebar, move with
the parent window, and do not support draggable regions (because they are
implemented using sheets). On Linux disabling the parent window controls
requires a window manager the supports _NET_WM_STATE_MODAL.

Browser modal dialog behavior is similar on all platforms. The dialog will
be automatically sized and positioned relative to the parent window's
browser view. Closing the parent window or navigating the parent browser
view will dismiss the dialog. The dialog can also be moved independent of
the parent window though it will be recentered when the parent window
itself is resized or redisplayed. On MacOS the dialog will move along with
the parent window while on Windows and Linux the parent window can be moved
independently.

To test: Use the Tests > Dialog Window menu option in cefclient with Views
enabled (`--use-views` or `--enable-chrome-runtime` command-line flag).
Browser modal dialog is the default behavior. For window modal dialog add
the `--use-window-modal-dialog` command-line flag.

Nik Pavlov 06af9c85da views: mac: Show standard window buttons with frame by default (see issue #3189)
This restores the previous default behavior for framed windows.

Nik Pavlov 276423dcfb views: mac: Fix frameless window behavior (fixes issue #3189)
Frameless windows now display as expected. Default traffic light buttons can
optionally be shown at configurable vertical position. Layout respects text
direction.

Marshall Greenblatt 882bc19fdd cefclient: views: Support window state restore (see issue #3359)
The cefclient sample app will persist window state across application restart
if run with views, cache_path and persist_user_references enabled.

To test:
1. Run `cefclient --use-views --cache-path=/path/to/cache --persist-user-preferences`
2. Move or resize the window, maximize, minimize, etc.
3. Exit cefclient.
4. Run cefclient again with the same arguments. The previous window state will
   be restored.

Marshall Greenblatt d8db6fa9da mac: cefclient: Use RootWindowManager to track key window status (fixes issue #3307)
This change provides a generic solution for active (key) window tracking that
works with both Views-hosted and native windows on MacOS. With this new approach
we can now successfully route top menu actions to the currently active window.

Prior to this change CEF's Views API was using focus notifications as a proxy
for window activation notifications. That doesn't work on MacOS where NSWindow
activation (key status) is independent of NSView focus (first responder) status,
and changes in activation don't necessarily generate focus notifications (see
NativeWidgetMac::OnWindowKeyStatusChanged). To make this work reliably on all
platforms we now expose a CefWindowDelegate::OnWindowActivationChanged callback.

This change also fixes an uninitialized variable
(RootWindowMacImpl::with_extension_) that was causing flaky behavior in
RootWindowManager::OnRootWindowActivated.

To test:
1. Run `cefclient [--use-views]`
2. Select Popup Window from the Tests menu. Do not explicitly activate the popup
   window (e.g. don't click on it).
3. Verify that further Tests menu actions go to the popup window.
4. Change activation to a first window by clicking on it. Verify that Test
   menu actions go to that window.
5. Close the currently active window. Do not explicitly activate the remaining
   window (e.g. don't click on it).
6. Verify that Test menu actions go to the only remaining window.

Marshall Greenblatt 9cff99dc4e Add support for loading extensions (issue #1947)
- Add CefRequestContext::LoadExtension, CefExtension, CefExtensionHandler and
  related methods/interfaces.
- Add chrome://extensions-support that lists supported Chrome APIs.
- Add CefBrowserHost::SetAutoResizeEnabled and CefDisplayHandler::OnAutoResize
  to support browser resize based on preferred web contents size.
- views: Add support for custom CefMenuButton popups.
- cefclient: Run with `--load-extension=set_page_color` command-line flag for
  an extension loading example. Add `--use-views` on Windows and Linux for an
  even better example.

Marshall Greenblatt 06e73fff15 Implement Views framework on Windows and Linux (issue #1749).
- Add Views header files in a new include/views directory.
- Add initial top-level window (CefWindow), control (CefBrowserView,
  CefLabelButton, CefMenuButton, CefPanel, CefScrollView,
  CefTextfield) and layout (CefBoxLayout, CefFlowLayout) support.
  See libcef/browser/views/view_impl.h comments for implementation
  details.
- Add Views example usage in cefclient and cefsimple and Views unit
  tests in cef_unittests. Pass the `--use-views` command-line flag to
  cefclient, cefsimple and cef_unittests to run using the Views
  framework instead of platform APIs. For cefclient and cefsimple
  this will create the browser window and all related functionality
  using the Views framework. For cef_unittests this will run all
  tests (except OSR tests) in a Views-based browser window. Views-
  specific unit tests (`--gtest_filter=Views*`) will be run even if
  the the `--use-views` flag is not specified.
- Pass the `--hide-frame` command-line flag to cefclient to demo a
  frameless Views-based browser window.
- Pass the `--hide-controls` command-line flag to cefclient to demo a
  browser window without top controls. This also works in non-Views
  mode.
- Pass the `--enable-high-dpi-support` command-line flag to
  cef_unittests on Windows to test high-DPI support on a display
  that supports it.
- Add CefImage for reading/writing image file formats.
- Add CefBrowser::DownloadImage() for downloading image URLs as a
  CefImage representation. This is primarily for loading favicons.
- Add CefMenuModel::CreateMenuModel() and CefMenuModelDelegate for
  creating custom menus. This is primarily for use with
  CefMenuButton.
- Add CefBrowser::TryCloseBrowser() helper for closing a browser.
  Also improve related documentation in cef_life_span_handler.h.
- Rename cef_page_range_t to cef_range_t. It is now also used by
  CefTextfield.
- Remove CefLifeSpanHandler::RunModal() which is never called.
- Add draggable regions example to cefclient.
