The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

Slightly less than half (93 / 210) of the NS_METHOD instances in the codebase
are because of the use of NS_CALLBACK in
nsI{Input,Output,UnicharInput},Stream.idl. The use of __stdcall on Win32 isn't
important for these callbacks because they are only used as arguments to
[noscript] methods.
This patch converts them to vanilla |nsresult| functions. It increases the size
of xul.dll by about ~600 bytes, which is about 0.001%.

This patch makes the following changes on many in-class methods.
- NS_IMETHODIMP F() override; --> NS_IMETHOD F() override;
- NS_IMETHODIMP F() override {...} --> NS_IMETHOD F() override {...}
- NS_IMETHODIMP F() final; --> NS_IMETHOD F() final;
- NS_IMETHODIMP F() final {...} --> NS_IMETHOD F() final {...}
Using NS_IMETHOD is the preferred way of marking in-class virtual methods.
Although these transformations add an explicit |virtual|, they are safe --
there's an implicit |virtual| anyway because |override| and |final| only work
with virtual methods.

This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other

This patch:
- Removes eTreeOpAddError{Atom,TwoAtoms}, which are unused.
- Adds a MOZ_CRASHing case for eTreeOpUninitialized.
- Reorders the cases in the switch to match the enum declaration order, which
makes it easier to see that all opcodes are now covered.
The web platform tests changes are just a cherrypick of
https://github.com/w3c/web-platform-tests/pull/2926 so I don't have to add
failure annotations until the next test uplift.
I've audited our uses of nsIFormControl, and this patch looks to me like it
preserves existing behavior in all but the following cases:
1) nsXBLPrototypeHandler::DispatchXBLCommand, the case of scrolling when space
is pressed while something inside a <label> is focused. We used to not scroll
in this situation; I think this is a bug, so I'm changing that behavior to
scroll instead.
2) In Accessible::RelationByType for the RelationType::DEFAULT_BUTTON case,
when mContent is a <label> we used to return its form's default submit element.
Now we will just return Relation().
This avoids the need for some virtual function calls and also will help lead to
distinct representations for dynamic and static atoms.

This patch changes things so that dynamic atoms and static atoms have distinct
implementations. This is a step towards allowing dynamic atoms and static atoms
to have different layouts in memory, which will allow static atoms to be
represented more compactly.
Specifically, the patch does the following.
- It renames AtomImpl as DynamicAtom and PermanentAtomImpl as StaticAtom, and
the latter is no longer a subclass of the former. This required duplicating
some methods from the former into the latter: ScriptableToString(),
ToUTF8String(), ScriptableEquals(), IsStaticAtom(). (This duplication will
disappear in the future if the representations of dynamic atoms and static
atoms diverge. Indeed, SizeOfIncludingThis() is already different in the two
classes.)
- It replaces all mentions of "permanent"/"non-permanent" atoms with
"static"/"dynamic".
- In ~DynamicAtom() it removes the check that causes gAtomTable to be deleted
when it becomes empty. This will only happen at shutdown and so doesn't seem
useful.
- It documents better various things, especially the basics of the
dynamic/static split, the transmutation of dynamic atoms to static atoms, and
the details of the SizeOf functions.

They are kept around for the sake of the standalone glue, which is used
for e.g. webapprt, which doesn't have direct access to jemalloc, and thus
still needs a wrapper to go through the xpcom function list and get to
jemalloc from there.
It's no longer needed now that entry storage isn't allocated there. (The other
possible causes of failures in that function are less interesting and simply
crashing is a reasonable thing to do for them.)
This also makes PL_DNewHashTable() infallible, so I removed some
now-unnecessary checks of its result.

The distinction between moz_malloc/moz_free and malloc/free is not

I wouldn't be surprised if we are mixing them anyways.
I kept all the existing PL_DHashTableAdd() calls fallible, in order to be
conservative, except for the ones in nsAtomTable.cpp which already were
followed immediately by an abort on failure.

It feels safer to use a function with a new name, rather than just changing the
behaviour of the existing function.
For most of these cases the PL_DHashTableLookup() result was checked with
PL_DHASH_ENTRY_IS_{FREE,BUSY} so the conversion was easy. A few of them
preceded that check with a useless null check, but the intent of these was
still easy to determine.
I'll do the trickier ones in subsequent patches.

Currently the setting of PLDHashTable::ops is very haphazard.
- PLDHashTable has no constructor, so it's not auto-nulled, so lots of places
null it themselves.
- In the fallible PLDHashTable::Init() function, if the entry storage
allocation fails we'll be left with a table that has |ops| set -- indicating
it's been initialized -- but has null entry storage. I'm not certain this can
cause problems but it feels unsafe, and some (but not all) callers of Init()
null it on failure.
- PLDHashTable does not null |ops| in Finish(), so some (but not all) callers
do this themselves.
This patch makes things simpler.
- It adds a constructor that zeroes |ops|.
- It modifies Init() so that it only sets |ops| once success is ensured.
- It zeroes |ops| in Finish().
- Finally, it removes all the now-unnecessary |ops| nulling done by the users
of PLDHashTable.
