Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

The DoMouseClick helper is also removed because no other caller can now pass a null aEvent. Other MouseClicked implementations are also updated since aEvent cannot be null, which was already the case.

The schema handling for this is currently a bit ugly, for the sake of
simplifying uplift. In the figure, we should find a way to change the schema
pattern matching based on whether or not the extension is privileged.

These were found using some ugly text searches, so it's possible some unused
atoms remain. In the future, we should enforce removing unused atoms using
static analysis. Or just generate the static atoms table based on string atom
names in our code.
This patch leaves unused RDF atoms in place, since those are being dealt with
in another bug.

For reasons unknown, if you give MSVC:
// Foo.h
struct Foo
{
...
};
extern const Foo gFoo;
// Foo.cpp, which necessarily includes Foo.h.
extern constexpr Foo gFoo = {
};
MSVC will create a static initializer for gFoo and place it in the
read/write data section, rather than the read-only data section.
Removing the `extern const` declaration seems to be enough to make this
problem go away. We need to adjust the declaration of other variables
to compensate for the non-visibility of gFoo in the header file.
Due to the decision to keep the old API on nsXPTInterfaceInfo in part 4, this is
a fairly straightforward patch.
1. I had to change a couple of consumers of `IsRetval()` due to the movement of
that flag.
2. I changed all code which held a nsIInterfaceInfo to hold an `const
nsXPTInterfaceInfo*` instead.
3. I changed code which used the nsIInterfaceInfoManager to instead call the
static methods on nsXPTInterfaceInfo.
This removes properties of XULElement that can easily seen to be unused, even if the attributes they control are still in use. There are other properties that may still be used once or twice, and they are not removed here.

Each nsStaticAtomSetup contains a pointer to a static atom, and also a pointer
to the canonical pointer to that static atom. Which is pretty weird! The
notable thing thing about it is that these structs are in an array, and that
gives us the only way to iterate over all static atoms in a single class, for
registration and lookups.
But thanks to various other recent changes to the implementation of static
atoms, we can now put the static atoms themselves into an array, which can be
iterated over. So this patch does that. With that done, nsStaticAtomSetup is no
longer necessary.
According to the `size` utility, on Linux64 this reduces the size of libxul.so
by the following amounts:
> text: 62008 bytes
> data: 20992 bytes
> bss: 21040 bytes
> total: 104040 bytes
- The bss reduction is one word per atom, because the canonical static atom
pointers (e.g. nsGkAtoms::foo) have moved from .bss to .data, because they're
now initialized at compile time instead of runtime.
- The data reduction is one word per atom, because we remove two words per atom
for the nsStaticAtomSetup removal, but gain one word per atom from the
previous bullet point.
- I'm not sure about the text reduction. It's three words per atom. Maybe
because there is one less relocation per atom?
Other notable things in the patch:
- nsICSSAnonBoxPseudo and nsICSSPseudoElement now inherit from nsStaticAtom,
not nsAtom, because that's more precise.
- Each static atoms array now has an enum associated with it, which is used in
various ways.
- In the big comment about the macros at the top of nsStaticAtom.h, the pre-
and post-expansion forms are now shown interleaved. The interleaving reduces
duplication and makes the comment much easier to read and maintain. The
comment also has an introduction that explains the constraints and goals of
the implementation.
- The SUBCLASS macro variations are gone. There are few enough users of these
macros now that always passing the atom type has become simpler.

This will allow us to work with direct pointers to static atoms that are

that are initialized at runtime.

In SourceSurfaceImage::GetTextureClient, we use LookupForAdd. This is
because we typically will create a new TextureClient if there isn't
already one created. This creation can fail because the size is too big,
or we don't have the memory available for it. Unfortunately LookupForAdd
is an infallible operation; it is expected we will always add something
to the hashtable if we don't find an entry. This patch adds an OrRemove
method to cover the corner case where we are unable to complete the
insertion.
The last piece of code that was using these attributes was removed in

Currently static atoms are stored on the heap, but their char buffers are
stored in read-only static memory.
This patch changes the representation of nsStaticAtom (thus making it a
non-trivial subclass of nsAtom). Instead of a pointer to the string, it now has
an mStringOffset field which is a 32-bit offset to the string. (This requires
placement of the string and the atom within the same object so that the offset
is known to be small. The docs and macros in nsStaticAtom.h handle that.)
Static and dynamic atoms now store their chars in different ways: nsStaticAtom
stores them inline, nsDynamicAtom has a pointer to separate storage. So
`mString` and GetStringBuffer() move from nsAtom to nsDynamicAtom.
The change to static atoms means they can be made constexpr and stored in
read-only memory instead of on the heap. On 64-bit this reduces the per-process
overhead by 16 bytes; on 32-bit the saving is 12 bytes. (Further reductions
will be possible in follow-up patches.)
The increased use of constexpr required multiple workarounds for MSVC.
- Multiple uses of MOZ_{PUSH,POP}_DISABLE_INTEGRAL_CONSTANT_OVERFLOW_WARNING to
disable warnings about (well-defined!) overflow of unsigned integer
arithmetic.
- The use of -Zc:externConstexpr on all files defining static atoms, to make
MSVC follow the C++ standard(!) and let constexpr variables have external
linkage.
- The use of -constexpr:steps300000 to increase the number of operations
allowed in a constexpr value, in order to handle gGkAtoms, which requires
hashing ~2,500 atom strings.
The patch also changes how HTML5 atoms are handled. They are now treated as
dynamic atoms, i.e. we have "dynamic normal" atoms and "dynamic HTML5 atoms",
and "dynamic atoms" covers both cases, and both are represented via
nsDynamicAtom. The main difference between the two kinds is that dynamic HTML5
atoms still aren't allowed to be used in various operations, most notably
AddRef()/Release(). All this also required moving nsDynamicAtom into the header
file.
There is a slight performance cost to all these changes: now that nsStaticAtom
and nsDynamicAtom store their chars in different ways, a conditional branch is
required in the following functions: Equals(), GetUTF16String(),
WeakAtom::as_slice().
Finally, in about:memory the "explicit/atoms/static/atom-objects" value is no
longer needed, because that memory is static instead of heap-allocated.

It seems silly to have a tiny utils class with a single function in its own
module. This patch moves it into nsStaticAtom.h/nsAtomTable.cpp. It also
renames nsAtomListUtils as nsStaticAtomUtils. Finally, it uses templates to
remove the need for the `aCount` parameter at callsites.

Most of the noise is from the fact that clang-format on parser/html/*.{h,cpp}
reformatted all sorts of stuff. Not running it caused lots of format changes
from the generator... I guess we changed the format rules since the last time
