The base implementation of accFocus can't handle the case when a remote document has focus and just returns no focus (VT_EMPTY).
Override accFocus on the root accessible to try the accessible for the remote document in the active tab in this case.
This fixes focus loss with NVDA when dismissing the System menu.

1. Bug 1363595 added support for retrieving accDefaultAction from the cache, but the value was never cached in the first place.
This would have meant that accDefaultAction was returning nothing to clients.
2. Since accDefaultAction is the name of the first action, we can also use this cached value for IAccessibleAction::name for index 0.

The handler's implementation of IAHyperlink just forwards calls through to the proxy.
However, it exists because we want the cache to be used when a hyperlink is retrieved.
When querying from the handler to IAHyperlink, we should use the same implementation.
This is mostly about consistency/correctness, especially as we're increasing complexity.

The proxy manager caches interfaces marshaled in the payload and returns them on QI without a cross-process call.
However, it doesn't know about interfaces which don't exist.
We can determine this from the payload, since interfaces which don't exist will have a null pointer.
We use this information to avoid querying the proxy in this case.

Now that virtual buffers have to render across processes, we want to eliminate as many cross-process calls as possible.
This includes QueryInterface calls, since buffers query for several interfaces on every node they visit.
To avoid these cross-process QI calls, we include interfaces clients are likely to request in the handler payload.
This way, they get marshaled in the single call used to retrieve the object.
This patch does the following:
1. Passes the interceptor when building the payload.
We need this so we can get interceptors for other interfaces.
2. Splits the payload into two main parts: a static part and a dynamic part.
The (new) static part contains the interface pointers. The dynamic part contains the rest.
This is necessary because the refresh call cannot pass the interceptor, but the interceptor is needed to build the static part.
Also, re-building the static part is pointless when refreshing.
3. Includes the interface pointers in the payload (BuildStaticIA2Data).
The pointers also have to be cleaned up after marshaling.
4. Releases the interface pointers in the handler after the payload is received.
We do this because they're aggregated by the proxy manager as they're unmarshaled.

AccessibleHandler's AccessibleTextTearoff currently makes separate queries for the IAccessibleText and IAccessibleHypertext interfaces.
However, IAccessibleHypertext inherits from IAccessibleText, and wherever one of these interfaces are present, Gecko always implements both.
Therefore, we should just query for and use IAccessibleHypertext for all of these methods, thus saving a cross-process call should a client want both interfaces.

When we only have a single process, this can be (and was previously) handled the same way as any other relation.
However, for multi process, the normal relation mechanism doesn't work because it can't handle remote objects.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

The first accessibility client to ask for the root accessible will get a surrogate LazyInstantiator object. That instantiates accessibility if appropriate and then passes calls through.
However, it previously didn't implement accNavigate, which broke things for clients that used this on the root.
In particular, this was bad for NAVRELATION_EMBEDS, which is used by some clients to retrieve the tab document.
This patch simply passes accNavigate through to the real accessible, just as is already done for other methods.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

nsIEventListenerChange::changedListenerNames is an nsIArray attribute that
contains nsIAtoms. Bug 1396693 made it `noscript` to help with nsIAtom
deCOMtamination (bug 1392883) but more changes are needed: that array
eventually needs to be changed to nsTArray<RefPtr<nsIAtom>>.
Turns out the attribute has a single use, in a11y code. That code merely
iterates over the list and counts how many atoms it contains that match
"onclick", "onmousedown", and "onmouseup".
So this patch moves that counting functionality inside nsEventListenerChange by
changing the attribute to `countOfEventListenerChangesAffectingAccessibility`.
This saves us from having to expose the array of atoms via XPIDL.

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to

"deprecatedReferrerDirective" in nsCSPParser.cpp.)
