The patch also const-ifies a bunch of nearby fields.

Various places in dom/ use the pattern:
already_AddRefed<NodeInfo> ni = ...;
which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason. To fix our static analysis code, we need to
eliminate instances of the above pattern.
Unfortunately, eliminating this pattern requires restructuring how Nodes
are created. Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`. We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.
Mostly automatic via sed. Only parts which I touched manually (apart from a
couple ones where I fixed indentation or which had mispelled arguments) are the
callers. I may have removed a couple redundant `virtual` keywords as well when
I started to do it manually, I can revert those if wanted.
Most of them are just removing the argument, but in Element.cpp I also added an
assertion for GetBindingParent when binding the ShadowRoot's kids (the binding
parent is set from the ShadowRoot constructor, and I don't think we bind a
shadow tree during unlink or what not which could cause a behavior difference).

This was a memory-saving optimization introduced as part of dependencies for bug
686875, but a more general system landed in bug 77999 for Gecko and
https://github.com/servo/servo/pull/18509 for Servo.
So now it's probably even a bit of a pessimization (though probably not huge),
and given this causes bugs like bug 1462742, bug 1157592, and bug 1468145, and
fishiness like the one pointed out in this bug, we may as well remove it.
The performance impact of having to lookup through more rules should be minimal
given the bloom filter and the rule hash optimizations.
This makes me wonder whether we could remove the whole concept of on-demand UA
sheets, since they've caused pain, for example, when the frontend people try
loading <svg>s from NAC (since that triggers sheet loading from frame
construction, which is not good). I'm not concerned about loading mathml.css and
svg.css everywhere, though xul.css may not be as doable since it adds a bunch of
attribute-dependent selectors. Though on the other hand I asserted in the
xul.css code and we don't load it in content with <video> / <input
type="date/time/etc"> and such, afaict, so maybe now that legacy addons are gone
we can remove that sheet from content processes altogether.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

In practice, this shouldn't make a difference -- but C++ allows compilers to
make pointer-usage-after-delete trigger a runtime fault.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
