Since our platform requirement is Windows 7+, we don't need GetProcAddress for gesture APIs. But nsWinGesture still uses GetProcAddress for Win7+ API.

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.

WebKit's Speedometer benchmark updates textbox to emulate text input. So it also updates caret position with focus. And, nsCaret always gets current blink time when reseting caret via LookAndFeel.
When profiling speedometer benchmark, GetCaretBlinkTime somestimes show profiling stack. This API gets data from kernel mode, so this isn't faster.
So, we should cache caret blink rate.
And when changing this rate via control panel, WM_SETTINGCHANGE is posted. So we should update this cache via this message.

SetParent removes the widget from the old parent widget and then sets its new one. We were incorrectly using the new parent widget when we needed the old one.
It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.
In TSF mode, application should retrieve messages with ITfMessagePump::GetMessage() or ITfMessagePump::PeekMessage() since TSF/TIP may handle the message before or after the host application handles it.
This patch rewrites the API users with WinUtils::(Get|Peek)Message() which use ITfMessagePump if it's available.

Due to Windows doesn't support dnd in the pen message handler, we can't handle and consume WM_POINTER* to fire WidgetMouseEvent. On the other hand, we can't get some pen related attributes from Windows mouse messages. This patch gets and caches the attributes by handling WM_POINTER* but not fire WidgetMouseEvent to support dnd and pen related attributes. When handling the subsequent Windows mouse messages, we use the cached attributes to fire WidgetMouseEvent. Considering we might need to use WM_POINTER* someday, use a preference to control the behavior.

ScreenHelperWin is the platform dependent part of the original
nsScreenManagerWin and nsScreenWin. It listens the WM_DISPLAYCHANGE
message and pushes updates to ScreenManager. See patch part 4. for how
ScreenManager works.

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.

There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.
