To make the HeadlessCompositorWidget work under Windows as well as Linux, I had
to change the way that I hooked it into the existing CompositorWidget system.
Under GTK, the CompositorWidgetInitData and CompositorWidgetDelegate types
provided the information needed by the headless compositor widget already (the
widget client size). On Windows, however, the definitions of these types
differ, and the client size information is simply retrieved from the platform
APIs when needed.
After this patch, CompositorWidgetDelegate is renamed to
PlatformCompositorWidgetDelegate, and a new base class called
CompositorWidgetDelegate is added with "AsPlatformSpecificDelegate()" and
"AsHeadlessCompositorWidget()" methods. In non-headless mode, widgets use
AsPlatformSpecificDelegate() to access the Windows- and GTK-specific delegate
APIs. In headless mode, AsHeadlessCompositorWidget() is used to access the
singular CompositorWidget implementation for headless. Meanwhile, the
CompositorWidgetInitData IPDL type is made into a union which always contains a
headless-specific HeadlessCompositorWidgetInitData struct and under GTK and
Windows also contains an {X11,Win}CompositorWidgetInitData struct.
This also includes a small patch to ensure that the GPU process and
hardware-accelerated compositing are always disabled under headless mode. These
features weren't activated by default in the Linux environments I tested in, but
did end up activating (and then promptly crashing Firefox) when I tested on
Windows.

Everything depending on the widget being gonk can go away, as well as
everything depending on MOZ_AUDIO_CHANNEL_MANAGER, which was only
defined on gonk builds under b2g/ (which goes away in bug 1357326).

Supports creating a windowless browser on Linux without an X server. Most of the
changes are just adding branches to avoid calls in to GTK which calls
into X. Some of the bigger additions were adding a separate headless widget
which implements just enough to render a page. A headless look and
feel were also added since there are many calls into GTK in the platform
specific one.
This is the most important part of the patch series. It removes the
PScreenManager protocol and use ScreenManager directly in the content
processes.
Initial and subsequent updates are sent via PContent::RefreshScreens.
struct ScreenDetails are kept to serialize Screen over IPC.
nsIScreenManager::ScreenForNativeWidget is removed because
nsIWidget::GetWidgetScreen can replace it. nsIScreen::GetId is removed
because it's not useful for the more general Screen class.

ScreenManager takes the common parts of ScreenManagerWin,
ScreenManagerGtk and ScreenManagerCocoa. It caches all screen
information in the new Screen class. The cache are updated when the OS
notifies there is a monitor config change; all changes will be pushed to
content processes via PContent (patch part 6.)
Screen is a pure data object. All platform dependent logic will be in
widget specific helper classes.
Each process will have a singleton ScreenManager object. Widget
specific helper object is held alive by the ScreenManager when
necessary, for example to receive updates from the OS.
The change to to VsyncDispatcher.cpp is due to unified-build bustage.
ScreenManager::ScreenForNativeWidget is not implemented because it
will be removed in patch part 6.

This just decouples nsAutoRollup from the widget class, which it isn't really
bound to anyway because the internal data is static. We'll need to be able to
use nsAutoRollup independently in the next patch.

nsPrintingPromptServiceX doesn't use Objective-C, so we should change to C++ instead.
Also, nsPrintDialogServiceX::ShowPageSetup should have NS_OBJC_BEGIN_TRY_ABORT_BLOCK_NSRESULT.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

When PluginInstanceChild receives native key events, it should post the events to the chrome process first for checking if the key combination is reserved. However, posting all key events to the chrome process may make damage to the performance of text input. Therefore, this patch starts to post a key event whose key combination may be a shortcut key. However, for avoiding to shuffle the event order, it posts following key events until all posted key events are handled by the chrome process.
For receiving response from widget, this patch defines nsIKeyEventInPluginCallback. It's specified by nsIWidget::OnWindowedPluginKeyEvent() for ensuring the caller will receive the reply. Basically, the caller of nsIWidget::OnWindowedPluginKeyEvent() should reply to the child process. However, if the widget is a PuppetWidget, it cannot return the result synchronously. Therefore, PuppetWidget::OnWindowedPluginKeyEvent() returns NS_SUCCESS_EVENT_HANDLED_ASYNCHRONOUSLY and stores the callback to mKeyEventInPluginCallbacks. Then, TabParent::HandledWindowedPluginKeyEvent() will call PuppetWidget::HandledWindowedPluginKeyEvent().

This also changes aPrintToFileName parameter for BeginDocument to an nsAString& from char16_t*.
Having a char16_t* caused a pain with VS2105 where wchar_t != char16_t (as on VS2103), after it had been sent over IPDL.
This could have been worked around with casting, but this seemed like the tidier solution.
