Most preference callbacks use literal strings for their domain filters, which
means that there's no need to make copies of them at all. Currently, however,
every preference observer node makes a separate heap-allocated copy of its
domain string.
This patch switches the domain string storage to nsCString instances, which
dramatically reduces the amount of unnecessary copies, at the expense of
making the callback nodes slightly larger.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

This reduces memory usage because we only need one allocation instead of two
for the dynamic atom and its chars, and because we don't need to store a
refcount and a size. It precludes sharing of chars between dynamic atoms, but
we weren't benefiting much from that anyway.
This reduces per-process memory usage by up to several hundred KiB on my
Linux64 box.
One consequence of this change is that we need to allocate + copy in
DOMString::SetKnownLiveAtom(), which could make some things slower.

After fixing the document.domain exceptions to conform to the html
spec, NS_ERROR_DOM_BAD_DOCUMENT_DOMAIN is no longer used, and can be
removed.

This adds 'CorruptionCanaryForStatics', which as the name implies is suitable
for use in objects that are statically declared. It has a trivial destructor
which allows us to avoid the need for static constructors.

HashStore::ApplyUpdate() is a V2-only function and so we can be
explicit about that and remove unnecessary casts.
Add a new update error code for when we fail to cast a TableUpdate
object to the expected protocol version.

Inheriting PerThreadAtomCache on CycleCollectedJSContext permits use of
static_cast, avoiding one level of indirection compared to adding a
CycleCollectedJSContext* to PerThreadAtomCache.
PerThreadAtomCache is over 18kB, and so WorkerJSContext and WorkletJSContext
are moved from the stack to the heap.

Currently we call JSPurpleBuffer::Destroy from
nsCycleCollector::PrepareForGarbageCollection. If the CC is shut down after a call to
nsCycleCollector::GetJSPurpleBuffer (which creates a JSPurpleBuffer) but before a GC
happens, we'll release the strong reference in mJSPurpleBuffer from nsCycleCollector's
destructor but we won't call JSPurpleBuffer::Destroy. That leaves a stale pointer to the
JSPurpleBuffer in the JSHolder's hash.

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 :)

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

This patch defines NS_ERROR_EDITOR_DESTROYED error code as an editor module
specific error code.
And creates TextEditRules::CanHandleEditAction() to check if the instance
can keep handling edit action.

They're very similar as far as most users of the profiler are concerned, I'd
say, and I don't believe it's worth giving them two different colors in the
activity graphs.

Using concrete class types with static IIDs in QueryInterface methods is a
pretty common pattern which isn't supported by any existing helper macros.
That's lead to separate ad-hoc implementations, with varying degrees of
dodginess, being scattered around the tree.
This patch adds a helper macro with a canonical (and safe) implementation, and
updates existing ad-hoc users to use it.
