One file was excluded for using plarena which it did not. The other was
excluded for "clashes with strdup," it does not use strdup.

A general outline of the COM handler (a.k.a. the "smart proxy"):
COM handlers are pieces of code that are loaded by the COM runtime along with
a proxy and are layered above that proxy. This enables the COM handler to
interpose itself between the caller and the proxy, thus providing the
opportunity for the handler to manipulate an interface's method calls before
those calls reach the proxy.
Handlers are regular COM components that live in DLLs and are declared in the
Windows registry. In order to allow for the specifying of a handler (and an
optional payload to be sent with the proxy), the mscom library allows its
clients to specify an implementation of the IHandlerProvider interface.
IHandlerProvider consists of 5 functions:
* GetHandler returns the CLSID of the component that should be loaded into
the COM client's process. If GetHandler returns a failure code, then no
handler is loaded.
* GetHandlerPayloadSize and WriteHandlerPayload are for obtaining the payload
data. These calls are made on a background thread but need to do their work
on the main thread. We declare the payload struct in IDL. MIDL generates two
functions, IA2Payload_Encode and IA2Payload_Decode, which are used by
mscom::StructToStream to read and write that struct to and from buffers.
* The a11y payload struct also includes an interface, IGeckoBackChannel, that
allows the handler to communicate directly with Gecko. IGeckoBackChannel
currently provides two methods: one to allow the handler to request fresh
cache information, and the other to provide Gecko with its IHandlerControl
interface.
* MarshalAs accepts an IID that specifies the interface that is about to be
proxied. We may want to send a more sophisticated proxy than the one that
is requested. The desired IID is returned by this function. In the case of
a11y interfaces, we should always return IAccessible2_3 if we are asked for
one of its parent interfaces. This allows us to eliminate round trips to
resolve more sophisticated interfaces later on.
* NewInstance, which is needed to ensure that all descendent proxies are also
imbued with the same handler code.
The main focus of this patch is as follows:
1. Provide an implementation of the IHandlerProvider interface;
2. Populate the handler payload (ie, the cache) with data;
3. Modify CreateHolderFromAccessible to specify the HandlerPayload object;
4. Receive the IHandlerControl interface from the handler DLL and move it
into the chrome process.
Some more information about IHandlerControl:
There is one IHandlerControl per handler DLL instance. It is the interface that
we call in Gecko when we need to dispatch an event to the handler. In order to
ensure that events are dispatched in the correct order, we need to dispatch
those events from the chrome main thread so that they occur in sequential order
with calls to NotifyWinEvent.

This patch needs to use different manifests depending on whether we are building
32-bit or 64-bit Firefox. In order to distinguish between them, I am using
checking for HAVE_64BIT_BUILD in the resource file and embedding the manifests
there.

Initializing nsSystemInfo can't be done off the main thread on
Windows, and we can't guarantee that it has been initialized before
calling this code.

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.

This merges two existing off-main-thread sync IPCs into a single operation. We
will change them into a single async operation in a follow up.

- PVRManager::GetDisplays was a sync IPC that was part of an optimization
for a use case that has been eliminated by changes to the WebVR spec.
- This was an optimization for Navigator.activeVRDisplays that would allow
enumeration of displays active in any content process without powering
on any additional VR hardware. This will no longer be necessary as the
activeVRDisplays has been restricted to returning only the displays
active in the current javascript context.
