The new telemetry tag is for probing the best IPC message pre-allocate size to avoid
realloc overhead. We only count those message size which is greater than 4096.
This tag integrates IPC_MESSAGE_SIZE and MESSAGE_MANAGER_MESSAGE_SIZE2 which
have both expired.

Takes functionality that was in the WebAuthentication class that now
needs to be handled by the parent process, and moves it to the
U2FTokenManager singleton class. U2FTokenManager is created on the
PBackground thread during the first WebAuthn transaction, and manages
hardware access and transaction management for the lifetime of the
browser session. Patch also adds parent classes for WebAuthn IPC
protocol.

Takes functionality once in the WebAuthentication DOM class that needs
to be handled by the content process, and moves it to a
singleton (per-content-process) manager class. This allows the
WebAuthn API to centralize management of transactions and IPC
channels. Patch also creates the child (content-process) classes for
WebAuthn IPC channels.

We proxy all accessibility information for the content through the main process
so its unnecessary and possibly confusing to expose accessibility information
from the content processes. Further ATK's use of dbus uses syscalls that we
would like to disallow within sandboxed content processes.
PLayerTransaction's constructor was previously synchronous so we could
return a TextureFactoryIdentifier. This is quite reliably available
already in the case of opening a tab, due to RenderFrameParent knowing
which compositor it is attached to, so we can make the constructor
asynchronous.
In the top-level widget case, we add a new synchronous message to find
the TextureFactoryIdentifier.

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
majority of its caller. This patch makes it optional. Notably, this makes
ProcessCreation() easier to use in a constructor's initializer list.
In order to avoid a busy wait where we defer and then immediately un-defer a message,
we need to ensure that we only un-defer a message if it's actually ready to be processed.
This patch uses the same condition in MaybeUndeferIncall as we use in
DispatchInterruptMessage.

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.)

Remove sync protocol AllocateTabId. Instead we generate tabId in
each process with nsContentUtils::GenerateTabId, and register
RemoteFrameInfo in parent process. If the tab id was generated from
a content process, it's sent parent through either PBrowserConstructor
or PContent::CreateChildProcess.

This patch implements async returns for IPDL using MozPromises. There
are following changes:
* Initialize AbstractThreads for MessageLoops
* Record promises and their reject functions
* When async message returns, call their resolve functions
* When send error or channel close, call their reject functions
* Implement "unresolved-ipc-promises" count for about:memory
* Test cases
See bug attachment for generated code from test cases
