The layout module is a little weird. It's described as being loadable
in the GPU process, but very few of the contracts and CIDs it contains
are also marked as such. In fact, the sole reason the layout module is
marked as being loadable in the GPU process is so that the power manager
service can be registered; everything else is inconsequential. This
setup also means that the initializer for the layout module has to
specifically check whether it's running in the GPU process (or several
other processes...), so we don't try to spin up a bunch of stuff we
don't need, like xpconnect and similar.
This setup is silly: we should have a module solely for the power
manager's use and that module can be loaded in the GPU process. Then
the layout module can go back to being an ordinary module, and we don't
have to play games in its initialization method.
The concrete classes of nsIContentIterator are enough complicated, but they
are not tested simply. Therefore, it's dangerous to touch them even if we
meed bugs of them. Additionally, it's used in some hot paths, therefore,
I'd like to keep them simple as far as possible.
Therefore, this patch creates a mediator class between script and each
nsIContentIterator instance. So, this change shouldn't affect any of
actual behavior nor performance.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Without patch 1, this correctly triggers:
Assertion failure: !(bitsUsedPerGroup[group] & bit) (BULLET_FRAME_HAS_FONT_INFLATION must not use a bit already declared within its group), at /home/dbaron/builds/mozilla-central/mozilla/layout/generic/nsFrameStateBits.h:594

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.

JS is the only file extension actually supported, and there are a few
layers of cruft that can be eliminated if we specialize it.
This eliminates one XPCOM registration of the JS component loader.
Depends on D8170

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
nsISupports, so I changed the second argument to be a class unrelated
to the concrete class.
I also removed some useless null checks on the return value of new.
