This enables navigating by index in session history go through the
session history in the parent (if enabled with the pref).
If the pref is enabled, then ChildSHistory::Go will send an IPC message
to the parent with the index to navigate to. The parent calls the
existing nsSHistory implementation and starts the loads, and
asynchronously returns the index that we actually navigated to. The
child process then uses that result to update the session history
implementation in the child process (this part is temporary, while we
have session history both in parent and in child). We also make the
parent send an updated length to the child process over IPC, so that
history.length always the length for the implementation in the parent.

This adds a new implementation of nsISHEntry
(mozilla::dom::SessionHistoryEntry). When session history in the parent
is turned on, we'll instantiate the existing nsSHistory in the parent
process, but it will store entries of this new type. The nsSHistory in
the child process will also be instantiated for now, to avoid breaking
too many assumptions, and we try to keep parent and child
implementations in sync.
mozilla::dom::SessionHistoryEntry stores most of its data in a new
structure (mozilla::dom::SessionHistoryInfo) which can be sent over IPC.
When a load starts through the DocumentChannel we create an entry of
this new type for it in the parent process in
DocumentLoadListener::Open. The SessionHistoryInfo for that entry (with
an associated ID) is then sent over IPC in the RedirectToRealChannelArgs
to the process that does the actual load, where we store it in the
nsDocShell in mLoadingEntry (and mLoadingEntryId). The parent process
keeps track of outstanding loading entries in an array (mLoadingEntries)
in the CanonicalBrowsingContext. When a load finishes the nsDocShell
transfers mLoadingEntry into mActiveEntry, and notifies the parent
process through an IPC message (HistoryCommit) with the id of that
entry. The CanonicalBrowsingContext then removes the entry from the
array and stores it in its mActiveEntry, and adds the entry to the
nsSHistory object.
There are a number of things in this patch that are broken, and a lot of
FIXME comments. However, with the pref turned off things should just be
working as before. The goal is to land this first part, and then iterate
on the new implementation until we can switch over.

The existing infrastructure which stored cached BrowsingContexts on the
BrowsingContextGroup was added before WindowContexts were added, and can cause
racing issues with partially discarded trees during process switches.

TabGroup never really made any difference in which thread something go
dispatched to. This was the intended use, but development of TabGroups
with abstract main threads never made it that far. The good thing is
that thish makes it safe to also remove to the SystemGroup and instead
switch all SystemGroup dispatches to dispatches to main thread.
Timers for setTimeout and workers were the sole users of wrapped and
throttled event targets, that those throttled queues have been moved
to the BrowsingContextGroup and are now accessed explicitly.
The SchedulerEventTarget has been removed, since there are no longer a
separate event target for every TaskCategory. Instead a
LabellingEventTarget has been added to DocGroup to handle the case
where an event is dispatched do DocGroup or when an AbstractThread is
created using a DocGroup. This means that we'll actually label more
events correctly with the DocGroup that they belong to.
DocGroups have also been moved to BrowsingContextGroup.

WalkHistoryEntries function gets called by nsSHistory::CloneAndReplaceChild
and nsSHistory::SetChildHistoryEntry recursively, so those have to be moved
into the parent process. This eliminates many sync IPC calls.
To facilitate transition to a new session history design,
we are mirroring mOSHE and mLSHE SH entries from docshell to browsing context.
Whenever we update those entries in docshell, we will also update those in BC,
and vice versa.
