The lifetime of async IPDL returned promise may be longer than its actor.
That is, the handler (receiver) may have not resolve/reject the promise when the actor
is destroyed. In this case, we have to reject all the pending promises before
ActorDestroy() is called on the "sender" side.
Besides, the handler (receiver) can reject with reason "ActorDestroyed" to silently
cancel the promise without trying to reply to the remote actor which may
have died. The sender-side promise is responsible for rejecting the pending promises,
which will be done in MessageChannel::RejectPendingPromisesForActor().

This change moves most of the logic for the threadsafety check into
nsAutoOwningThread, rather than having part of the logic live in
nsAutoOwningThread and part of the logic live in nsDebug.h. Changing
this also forces us to clean up a couple of places that replicated the
logic that lived in nsDebug.h as well.
TimeStamp::ProcessCreations()'s aIsInconsistent outparam is ignored by the

ProcessCreation() easier to use in a constructor's initializer list.

IPCBlobInputStream must implement nsIIPCSerializableInputStream interface.
When this is done, the child sends the internal ID of the IPCBlobInputStream to
the parent.
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.
Change mozilla::Smprintf and friends to return a UniquePtr, rather than
relying on manual memory management. (Though after this patch there are
still a handful of spots needing SmprintfFree.)

The Makefile used to use EXTRA_DEPS to invoke the manifest tool when a manifest files is changed. But it is no longer effective because the manifest file namepattern is no longer $@.exe.manifest.
Now manifest files will be embedded via .res files. So we have to rebuild .res files to update embedded manifests.

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 removes the C++ code used to run the minidump analyzer when a
content process crashes, and replaces it with JS code within the CrashService
object. This removes the need for a separate shutdown blocker in C++ code and
allows end-to-end testing of the crash service functionality. Additionally
the exception handler code can be simplified since it's now only used to run
the crash reporter client.
The test added to test_crash_service.js covers computing the minidump SHA256
hash (bug 1322611) and of the minidump analyzer itself (bug 1280477).

An IPDL unit test that is intended to fail should check that the
reason the test fails matches the expected reason for failure. We have
had a number of cases where some change, like renaming a keyword,
causes tests to start failing for the wrong reason, which means they
are no longer testing anything useful.
To support this, each file in error/ must contain one or more error
annotations. An error annotation is a line starting with "//error:",
followed by whatever the rest of the expected error is. For every one
of these annotations that a file has, the stderr output of compiling
the test must contain the specified string, including the "error:". It
is also an error for an error/ file to not contain an error
annotation.
To generate the initial set of annotations, I just copied and pasted
the error that each test produced. I did some light auditing to check
that the errors are reasonable, which did turn up one minor error
which I fixed as part of bug 1347527.
This patch does not check that every error produced by compiling the
file is in the list of expected errors. I think that's less of a
problem if it does occur.
