The implementation is based on a cache (datastore) living in the parent process and sync IPC calls initiated from content processes.
IPC communication is done using per principal/origin database actors which connect to the datastore.
The synchronous blocking of the main thread is done by creating a nested event target and spinning the event loop.
Creates a FuzzyFox class for implementating the core of the step/sleep
algorithm. Starts it in nsLayoutStatics::Initialize()
Adds the fuzzyfox prefs.
Moves the ms2mt macros from TimeStamp_windows.cpp to TimeStamp_windows.h
and creates a new public function GetQueryPerformanceFrequencyPerSec() to
expose a static variable in the .cpp file. This is necessary to support
the macros being usable anywhere. (And we use the macros in FuzzyFox.)
This strategy allows us to dodge dynamic allocations in WebIDLGlobalNameHash.
This removes the Init() and Shutdown() methods, as well as Register. The
RegisterBindings.cpp file now only contains static data and one method
declaration for the WebIDLGlobalNameHash class.
This should also be faster by making the hashtable lookup infallible.

nsLayoutModule must be initialized in order to call into JS, but I
don't want to have to rely on calling a service in that
module. Instead, always initialize the module very early in component
manager initialization. This also makes initialization more
consistent, so things like errors in manifests won't affect when it
happens, which can result in different behavior in different builds.
I also made nsLayoutModule initialization infallible, because I can't
imagine that we can do much that is useful without it.
Another change I made is that gInitialized is set to true even in a
GPU process. This simplifies checking whether initialization has
happened already when we start up the layout module.

If a class A is derived from a class B, then an instance of A can be
converted to an instance of class B via a static cast, so QI is not
needed. QIs are slower than static casts.
TestCallTemplates seems to be testing that CallQueryInterface compiles
even if the first argument's class is only ambiguously castable to

All classes deriving from nsIFrame that did not have any subclasses themselves
(at the time of writing this patch) have been marked with `final`.
Some other Layout classes have also been made final, but this was opportunistic
while working on nsIFrame subclasses, and is definitely not exhaustive, further
patches welcome; refer to bug 1332680.
Advantages of marking a class final include:
- Allowing the compiler to devirtualize some method calls (i.e., calling
virtual functions directly instead of going through the vtable),
- Indicating that the class is not currently subclassed,
- Preventing subclassing without being aware that this would remove the
finalization benefits of the parent class.
`final` does not signify that these classes should *never* be subclassed, this
is left for developers to decide.

nsAutoCopyListener is a singleton class but refcountable and a selection
listener. nsFrameSelection adds it to only normal Selection when it's on
macOS or it's enabled by the pref. Additionally, it's always first selection
listener since it's added immediately after Selection instance is created.
So, we can make it a static class, and normal Selection instance should have
a bool to decide whether it should notify nsAutoCopyListener of its changes.
Then, we can save the cost of grabbing it with local RefPtr and the virtual
call.
Additionally, this patch renames nsAutoCopyListener to mozilla::AutoCopyListener
and optimizes constructor of nsFrameSelection (using bool var cache to retrieve
the pref, avoid retrieving the pref on macOS).

sTagAtomTable[] currently ends up holding duplicate pointers to the same static

The patch also moves some checking of sTagNames from RegisterAtoms() (which is

-Wmissing-prototypes is a new optional warning available in clang ToT. It warns about global functions that have no previous function declaration (e.g. from an #included header file). These functions can probably be made static (allowing the compiler to better optimize them) or they may be unused.
Confusingly, clang's -Wmissing-prototypes is equivalent to gcc's -Wmissing-declarations, not gcc's -Wmissing-prototypes. A function prototype is a function declaration that specifies the function's argument types. C++ requires that all function declarations specify their argument types, but C does not. As such, gcc's -Wmissing-prototypes is a C-only warning about C functions that have no previous function *prototypes* (with argument types), even if a previous function *declaration* (without argument types) was seen.

Various atom-related things have improved recently.
- The main atom table is now threadsafe (bug 1275755) and so can be accessed on
any thread. It has also been split into pieces (bug 1440824), which greatly
reduces lock contention.
- A cache has been added to the HTML5 parser (bug 1352874) that removes the
need for most of the full table lookups.
As a result, there is no point having a separate static atom table. This patch
removes it.

This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

So, if we have a IPCBlobInputStreamParent, we have an inputStream, and this

nsStyleContext::CalcDifference had an optimization where, when we knew
that the old and new style context have the same rule node, we knew that
the only change hints that would need to be handled are those in the
"not handled for descendants" category, generated due to explicit
'inherit' values on reset properties. This was because any changes due
to differences in inherited properties should only have generated
"handled for descendants" change hints (and thus would already have been
handled on an ancestor).
Before bug 931668, this let us avoid calling CalcDifference on structs
that only would have generated hints that we knew we already would have
handled. However, after bug 931668, we compare all structs anyway so
that we can set the aEqualStructs outparam, so we don't gain anything
from this optimization. We can still return these change hints we know
will not need to be handled, and rely on ElementRestyler::CaptureChange
to filter them out.
