that the event spent queued - which can be used to figure out 'jank' at the
time the event was queued. For PrioritizedEventQueues, only if such queuing
would delay an input event then the queuing delay is reported.

We need some way of differentiating "tasks that just consume CPU"
vs. "tasks that block on some external resource" like reading from a
socket or a file. If we didn't have this, we'd either a) have a thread
pool sized for the number of CPUs where having all the threads blocked
on I/O--and therefore no new tasks are able to run--or b) have a thread
pool that tries to increase the number of working threads based on the
number of submitted tasks and winds up having too many tasks running
with not enough CPUs to run them on.
This flag enables us to theoretically get the best of both worlds: we
can set aside `~#CPUs` threads for CPU-intensive work, and
`$SOME_NUMBER` threads for I/O work. The latter number can be adjusted
up if the I/O load on the system is particularly heavy.
The implementation strategy of this patch is to use two separate thread
pools for the two different kinds of work. It's entirely possible that
we'll want to use a single thread pool to coordinate thread create
between the two kinds of work, or even migrate threads from one kind of
work to the other, but such improvements can be future work. The focus
right now is providing the rest of Gecko with a common funnel to put
tasks into, and we can adjust what's at the end of the funnel at a later
point.

`TaskQueue` wraps an `nsIEventTarget` to provide "one runnable at a
time" execution policies regardless of the underlying implementation of
the wrapped `nsIEventTarget` (e.g. a thread pool). `TaskQueue` also
provides a `nsISerialEventTarget` wrapper, `EventTargetWrapper`, around
itself (!) for consumers who want to continue to provide a more
XPCOM-ish API.
One would think that dispatching tasks to `EventTargetWrapper` with a
given set of flags would pass that set of flags through, unchanged, to
the underlying event target of the wrapped `TaskQueue`.
This pass-through is not the case. `TaskQueue` supports a "tail
dispatch" mode of operation that is somewhat underdocumented. Roughly,
tail dispatch to a `TaskQueue` says (with several other conditions) that
dispatched tasks are held separately and not passed through to the
underlying event target. If a given `TaskQueue` supports tail dispatch
and the dispatcher also supports tail dispatch, any tasks dispatched to
said `TaskQueue` are silently converted to tail dispatched tasks. Since
tail dispatched tasks can't meaningfully have flags associated with
them, the current implementation simply drops any passed flags on the floor.
These flags, however, might be meaningful, and we should attempt to
honor them in the cases we're not doing tail dispatch. (And when we are
doing tail dispatch, we can verify that the requested flags are not
asking for peculiar things.)

The current API name is bad: we want it to be read "some background
thread", but it could just as easily be read "a singular background
thread", which would lead people to assume that for:
```
NS_DispatchToBackgroundThread(...);
NS_DispatchToBackgroundThread(...);
```
the dispatched tasks will necessarily run in the order they are
dispatched, which is not the case.
Let's try to head off that interpretation by renaming this function.

This function is needed for people whose needs don't map cleanly to

Eventually, we're going to want to hand out an `nsIEventTarget*` to people
wanting to dispatch to background threads, but for whatever reason not
wanting to use the `NS_DispatchToBackgroundThread` API (probably because
they want to verify correctness by checking that certain methods are, in
fact, running on the background event target). And because we're going to
want to have some sort of division between CPU-bound and IO-bound tasks, we
can't just hand out references to a single thread pool. We need some sort
of intermediate object for both of these goals, and that is what the added
`BackgroundEventTarget` class is.

It's fairly common for clients to hold a pointer to some private thread
and then inquire about `IsOnCurrentThread` in debug checks. As we
migrate these private threads into some `nsIEventTarget` implementation
that might be running on thread pools, we need to ensure that those
`IsOnCurrentThread` continues to be relatively cheap. The current
implementation for thread pools is not particularly efficient.
The inefficiency comes from having to iterate over all the threads in
the pool. But there's no need to do this; we can just have each thread
set a particular thread-local variable to the thread pool it's running
on, and check the value of that thread-local variable instead.

We have a number of people starting up singleton threads for the sole
purpose of running a single runnable on them. These consumers often
leave the thread running until some point close to shutdown, or they
never shut it down at all. Let's add a helper function to do the thing
they actually want to do, and then we can modify the implementation of
that function as necessary as we merge singleton threads (and even
thread pools) together.

This commit adds `ThreadPtr{Handle, Holder}` to wrap an `XpCom` object
with thread-safe refcounting. These are analagous to
`nsMainThreadPtr{Handle, Holder}`, but can hold references to
objects from any thread, not just the main thread.
`ThreadPtrHolder` is similar to `ThreadBoundRefPtr`. However, it's
not possible to clone a `ThreadBoundRefPtr`, so it can't be shared
among tasks. This is fine for objects that are only used once, like
callbacks. However, `ThreadBoundRefPtr` doesn't work well for loggers
or event emitters, which might need to be called multiple times on
the owning thread.
Unlike a `ThreadBoundRefPtr`, it's allowed and expected to
clone and drop a `ThreadPtrHolder` on other threads. Internally,
the holder keeps an atomic refcount, and releases the wrapped object
on the owning thread once the count reaches zero.
This commit also changes `TaskRunnable` to support dispatching from
threads other than the main thread.

The old code for member method calls did the following:
1) Find the member method calls.
2) Look at their "this" expression.
3) If the "this" is an operator call, check for any of the arguments of the
operator call being invalid.
4) Otherwise (if not an operator call) check for the "this" value being
invalid.
This wasn't right, because the "is invalid" check checks the type and only
considers refcounted things. So if the code looked something like
"foo[i]->call_method()", we would look at the types of "foo" and "i" and
determine that none of those are refcounted types so there is nothing invalid
here (since "foo" is some sort of array type and "i" is an integer). The new
setup just checks whether the "this" value is invalid, which does the type
check on the "this" value itself; in the "foo[i]->call_method()" case on
"foo[i]". We then adjust the exclusions in InvalidArg to consider operator->
on known-live things valid, to allow the thing that we were really trying to
accomplish with the "check for an operator call" bits:
"stackRefPtr->some_method()".
The test coverage being added for the made-up TArray type is meant to catch
things like the geolocation issue that was being hidden by the buggy behavior.
I'm not using nsTArray itself because some header included by nsTArray.h
tries to define operator new/delete bits inline and that triggers warnings that
then cause a clang-plugin test failure, because they're unexpected.

If main thread is busy handling runnables in the normal priority queue, control-type of messages from
workers are possibly postponed to run after those. That can lead to bad performance, if the page
expects workers to be able to proceed simultanously with the main thread.
This patch makes the control messages to use medium high priority queue in order to try to
ensure they are handled in timely manner.
Pref dom.worker.use_medium_high_event_queue can be set to false to disable this new behavior.

Counting CPUs accesses the filesystem (sysfs or procfs), which we'd like
to disallow when sandboxed if possible, and fails silently if access
is denied. Because the CPU count rarely changes, this patch handles
that problem for the RDD process by caching a copy before starting
sandboxing.
Tested with a local patch to have the sandbox file broker client crash
if accessing the sysfs node for the CPU count, to verify that it's not
accessed.

This is a follow-up to the previous part, which actually changes one of
these callers to use Array<nsIIDRef> instead of [array] nsIIDPtr.
From doing this patch, it seems like we should consider changing
the type `nsIIDRef` to instead simply be `nsIID`, and treat it more like
the `AString` types from the POV of XPIDL. `nsIIDPtr` would then
continue to exist for backwards compatibility, but we can probably
remove almost all current consumers over time.

We lose some sugar but gain some safety. This seems like the right
trade. If people want sugar they should use Rust.

This commit adds categories to all markers. This way the profiler's
marker categories and frame label categories agree. There are a few
duplicate category properties on some of the marker payloads, but
this could be cleaned up in a follow-up if needed.

nsTimerEvent goes through a multi-step initialization for reasons that
are lost to time. We are also seeing peculiar crashes in
`nsTimerEvent::SetTimer()` that are only explainable by `SetTimer`
finding a non-null pointer where there should have been a null pointer.
The compiler ought to have been able to optimize those bits away, but no
matter: we can do the job ourselves and make the code clearer.
Since we only call `SetTimer` once, we should just move its work into
nsTimerEvent's constructor.
Doing this code movement separately will ideally make the next part of
this work easier to review. The idea is that we want to extract all the
necessary information from `timer` before we pass ownership of it into
the newly-allocated nsTimerEvent.
Unlike many of our uses of `new`, nsTimerEvent has its own definition of
`operator new`, to ensure instances are allocated through
TimerEventAllocator. And allocating with TimerEventAllocator can fail.
Later changes, however, want to assume that constructing an nsTimerEvent
can't fail, which is difficult to guarantee with the current structure.
To make that guarantee, we need to make explicit what calling `new`
does: there's an "allocate memory" step and a "construct the object"
step. The first part can fail, and that's what we care about here.
Once we have a chunk of memory, we can construct the object as normal,
secure in the knowledge that calling (placement) `new` is now guaranteed
to succeed.
We introduce GenericNonExclusivePromise that can be used to explicitly state than non-exclusive use is needed
We temporarily disable the assertion ensuring a promise is used exclusively when needed to allow for things to settle.
