Currently, in order to retrieve supported clipboard formats
DataTransfer::CacheExternalClipboardFormats repeatedly makes the same calls to
clipboard->HasDataMatchingFlavors.
In the case when aPlainTextOnly == true only 1 call is made -
clipboard->HasDataMatchingFlavors(kUnicodeMime, ...), and when
aPlainTextOnly == false we have 1 call made for every member of the list
{ kCustomTypesMime, kFileMime, kHTMLMime, kRTFMime, kURLMime, kURLDataMime,
kUnicodeMime, kPNGImageMime } - a total of 8 calls.
We can see that in nsClipboardProxy::HasDataMatchingFlavors, there is a call to
ContentChild::GetSingleton()->SendClipboardHasType.
So when aPlainTextOnly == true, we will have 1 sync message, and when
aPlainTextOnly == false, we will have 8 sync messages.
With the proposed solution, in DataTransfer::CacheExternalClipboardFormats
we will only have 1 sync message regardless of the case because
GetExternalClipboardFormats() will retrieve all supported clipboard
formats at once.

Summary:
This patch adds the infrastructure to move Activity Stream (about:newtab, about:home,
and about:welcome) into its own special content process - the privileged content
process. This feature of running Activity Stream in the privileged content process
is disabled by default. (See "browser.tabs.remote.separatePrivilegedContentProcess"
preference.) We can deal with other about: pages in a follow-up.

This is fairly straightforward, other than the fact that the
nomenclature gets a bit awkward with the aForce parameter on
the ForcePaint methods. I'm not sure which direction to go with
this - "aForce" seems a fairly intuitive name for what we want,
and I'm kind of inclined to say the existing ForcePaint mechanic
should be renamed to something like PaintWithInterrupt, or
PaintWithPriority.

The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.
Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.

NO_REMOTE_TYPE seems to have been an artifact of introducing remote types and
not wanting to change things. This eliminates the type, changing
GetNewOrUsedBrowserProcess() to no longer use a default argument so that
callers must think about the remote type they want. Additionally, the existing
call-site used by xpcshell in nsEmbedFunctions.cpp is updated to use the
DEFAULT_REMOTE_TYPE of "web", as-is the unused nsAppRunner.cpp case. (That is,
no one appears to call nsXULAppInfo::EnsureContentProcess directly or via its
XPCOM interface, and so it probably should be removed. However, since I
potentially want this patch uplifted to beta 56 and legacy extensions exist
there, we're not addressing that in this patch.)

Without this patch, all remote process types share a process name of
"Web Content". With this patch, specific names are added for "file",
"extension", and "webLargeAllocationTypes", with the default of "web"
left as the default "Web Content".
This patch also eliminates undocumented b2g-era legacy logic that had a
notion of whether it's acceptable to override the process name. In the
b2g era, I believe processes were named based on the "app" that was
running. It would have made sense to have the process initially named
the preallocated process, then to change the process to its app name
when specialized, trying to make it hard/impossible for the process to
rename itself so it couldn't masquerade as another app if it became
compromised.

To prevent addons or other code to rapidly create and destroy content processes
under various conditions, we let the preallocated process manager to reuse short
lived content processes.
Every JS plugin is assigned a unique ID. When an instance of a JS plugin is created the
frame loader that we use to load the plugin's handler URI will create a special
TabContext. This TabContext causes the ContentParent to use the process for this specific
JS plugin (creating one if it hasn't already) when it creates the PBrowser actors.
This causes the iframes for all the instances of a specific JS plugin to be grouped in the
same process.

This patch replaces the usage of sNextTabParent pointer to store the next
PBrowser parent actor to be used by the next frame loader with the
following information:
* In the case where the content JS has requested a new tab, the ID of the
next TabParent will be stored on the <xul:browser> element.
* In the case where the content JS has requested a new window, the ID of
the next TabParent will be stored on the created nsXULWindow.
IPCBlobInputStream is a new type of nsIInputStream that is used only in content
process when a Blob is sent from parent to child. This inputStream is for now,
just cloneable.
When the parent process sends a Blob to a content process, it has the Blob and
its inputStream. With its inputStream it creates a IPCBlobInputStreamParent
actor. This actor keeps the inputStream alive for following uses (not part of
this patch).
On the child side we will have, of course, a IPCBlobInputStreamChild actor.
This actor is able to create a IPCBlobInputStream when CreateStream() is
called. This means that 1 IPCBlobInputStreamChild can manage multiple
IPCBlobInputStreams each time one of them is cloned. When the last one of this
stream is released, the child actor sends a __delete__ request to the parent
side; the parent will be deleted, and the original inputStream, on the parent
side, will be released as well.
IPCBlobInputStream is a special inputStream because each method, except for
Available() fails. Basically, this inputStream cannot be used on the content
process for nothing else than knowing the size of the original stream.
In the following patches, I'll introduce an async way to use it.
The goal of this patch is to remove the call to the sync IPC
GetCompositorOptions message from TabChild::InitRenderingState. In order
to this, we have InitRenderingState take the CompositorOptions as an
argument instead, and propagate that backwards through the call sites.
Eventually we can propagate it back to a set of already-sync IPC
messages in PCompositorBridge that are used during layers id
registration (NotifyChildCreated, NotifyChildRecreated, etc.). Therefore
this patch effectively piggybacks the CompositorOptions sync IPC onto
these pre-existing sync IPC messages.
The one exception is when we propagate it back to the AdoptChild call.
If this message were sync we could just use it like the others and have
it return a CompositorOptions. However, it is async, so instead we add
another call to GetCompositorOptions here temporarily. This will be
removed in the next patch.

We add a new "on-off" protocol PURLClassifierLocal which calls
nsIURIClassifier.asyncClassifyLocalWithTables on construction and
calls back on destruction. Pretty much the same design as PURLClassifier.
In order to avoid code duplication, the actor implementation is templatized
and |MaybeInfo| in PURLClassifier.ipdl is moved around.

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.
