We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

This patch is mainly to add a probe to measure sw launch time. To do this, this
patch records the sw launch time when the sw is just spwaned and it's ready to
handle the incoming fetch event.

This patch refactors the nsThread event queue to clean it up and to make it easier to restructure. The fundamental concepts are as follows:
Each nsThread will have a pointer to a refcounted SynchronizedEventQueue. A SynchronizedEQ takes care of doing the locking and condition variable work when posting and popping events. For the actual storage of events, it delegates to an AbstractEventQueue data structure. It keeps a UniquePtr to the AbstractEventQueue that it uses for storage.
Both SynchronizedEQ and AbstractEventQueue are abstract classes. There is only one concrete implementation of SynchronizedEQ in this patch, which is called ThreadEventQueue. ThreadEventQueue uses locks and condition variables to post and pop events the same way nsThread does. It also encapsulates the functionality that DOM workers need to implement their special event loops (PushEventQueue and PopEventQueue). In later Quantum DOM work, I plan to have another SynchronizedEQ implementation for the main thread, called SchedulerEventQueue. It will have special code for the cooperatively scheduling threads in Quantum DOM.
There are two concrete implementations of AbstractEventQueue in this patch: EventQueue and PrioritizedEventQueue. EventQueue replaces the old nsEventQueue. The other AbstractEventQueue implementation is PrioritizedEventQueue, which uses multiple queues for different event priorities.
The final major piece here is ThreadEventTarget, which splits some of the code for posting events out of nsThread. Eventually, my plan is for multiple cooperatively scheduled nsThreads to be able to share a ThreadEventTarget. In this patch, though, each nsThread has its own ThreadEventTarget. The class's purpose is just to collect some related code together.
One final note: I tried to avoid virtual dispatch overhead as much as possible. Calls to SynchronizedEQ methods do use virtual dispatch, since I plan to use different implementations for different threads with Quantum DOM. But all the calls to EventQueue methods should be non-virtual. Although the methods are declared virtual, all the classes used are final and the concrete classes involved should all be known through templatization.

nsIIOService based events when used via SpecialPowers in mochitests
combined with the preloaded browser in the same process can cause
IsSafeToRun() assertion in SchedulerGroup.h:81. To avoid that we make sure that
previous tests in the suit do not create a preloaded browser. This cannot happen
in a real life scenario.

This patch does 2 things:
. when SetBodyUsed() is called, the pump for the stream reading is activated.
. Just because of the reading of the stream could end up executing JS code, we
need to pass the JSContext in the correct state down to SetBodyUsed.
This removes about 2/3 of the occurrences of nsXPIDLString in the tree. The
places where nsXPIDLStrings are null-checked are replaced with |rv| checks.
The patch also removes a couple of unused declarations from
nsIStringBundle.idl.
Note that nsStringBundle::GetStringFromNameHelper() was merged into
GetStringFromName(), because they both would have had the same signature.

This also changes the Library window to use the newly added back-end object. The only user-visible change should be how the selection behaves when retrying downloads.

The fact that WorkerThread uses the mLock field from nsThread is a
pretty big hole in the nsThread abstraction. I don't see any reason
for the re-use, either. This locks protects a few fields inside
WorkerThread, but none of them seem in any way related to things
done by nsThread. This patch uses a separate lock for WorkerThreads.

This parameter isn't used by any implementation of onDispatchedEvent,
and keeping the parameter makes later refactorings in this bug more difficult.

Because we want to remove nsAdoptingString. We have other variants that don't
use nsAdoptingString, which can be used instead. There are three basic
patterns.
1. The easiest case is when we don't check for success.
> nsAdoptingString s = Preferences::GetString("foo");
> foo(s);
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> foo(s);
2. The next case is when we check if the result is empty.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s.IsEmpty()) { ... }
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> if (s.IsEmpty()) { ... }
3. The final case is when we null check the result.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s) { ... }
becomes:
> nsAutoString s;
> nsresult rv = Preferences::GetString("foo", s);
> if (NS_SUCCEEDED(rv)) { ... }
The patch also avoids some UTF8/UTF16 conversions in a few places.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

This patch reduces the differences between builds where the profiler is enabled
and those where the profiler is disabled. It does this by removing numerous
MOZ_GECKO_PROFILER checks.
These changes have the following consequences.
- Various functions and classes are now defined in all builds, and so can be
used unconditionally: profiler_add_marker(), profiler_set_js_context(),
profiler_clear_js_context(), profiler_get_pseudo_stack(), AutoProfilerLabel.
(They are effectively no-ops in non-profiler builds, of course.)
- The no-op versions of PROFILER_* are now gone. The remaining versions are
almost no-ops when the profiler isn't built.
