runnable is handled.
However, worker could terminate in any time, we still need to clear those

This reverts the available memory tracker back to its old implementation that
relied on GlobalMemoryStatusEx() instead of the potentially expensive
K32GetPerformanceInfo(). In spite of its name GlobalMemoryStatusEx() may return
per-process values instead of global ones which might lead to underestimating
the actual memory pressure. Because of this limitation this change is a
stop-gap while we replace this code with a non-polling implementation based on
QueryMemoryResourceNotification().

All calls to `profiler_add_marker()` (outside of the profilers code) are
now replaced by either:
- `PROFILER_ADD_MARKER(name, categoryPair)`
- `PROFILER_ADD_MARKER_WITH_PAYLOAD(name, categoryPair, TypeOfMarkerPayload,
(payload, ..., arguments))`
This makes all calls consistent, and they won't need to prefix the category pair
with `JS::ProfilingCategoryPair::`.
Also it will make it easier to add (and later remove) internal-profiling
instrumentation (bug 1576550), and to replace heap-allocated payloads with
stack-allocated ones (bug 1576555).

Whereas previously MozDescribeCodeAddress would have handled demangling,
we need to explicitly do that from our new GetFunction method. The string we
generate is now more useful for the profiler to merge -- having dropped the
address in the previous patch, and the file & line number and library in this
patch.
While we're at it, try to demangle Rust symbols too.
Ideally we'd add Rust symbol handling to DemangleSymbol in
StackWalk.cpp, but that lives in mozglue, which currently cannot have
any Rust crate dependencies.

This patch adds `RunOnShutdown`, which allows the caller to supply any callable
to be invoked during the specified shutdown phase. This allows us to do more
than just clear smart pointers without needing to write a bunch of observer
service boilerplate.
We use `std::function` to hold the callable.

JSClass contained void* members corresponding to the internal pointer members of js::Class. This stores the internal members in JSClass and removes js::Class.
This leaves js::Class aliased to JSClass while we remove references to it. I also aliased Jsvalify and Valueify into global scope temporarily to make this compile. These get removed in the following patches.
I had to remove a few functions which now don't compile with js::Class being the same type as JSClass.

We always define it to the same thing, and we're inconsistent in whether
we use `CPP_THROW_NEW` or `throw()`, so we might as well just use the
standard C++ thing and get rid of some baggage.

Patch to report JS GC things that are live at shutdown as leaks by calling MOZ_LOG_CTOR for them. The JS engine now clears any remaining roots to prevent dangling pointers to freed memory after shutdown. I made XPCJSRuntime::Shutdown keep the weak pointer update callbacks as sometimes these tables have entries remaining at shutdown (if there are leaks) and we need the callbacks to update them.
This is looking more green on try now.

The new StaticLocalAutoPtr smart pointer has a trivial destructor, so we will
either properly clean up this data or leak it on process shutdown. Either way,
we will not destroy it in a way that the underlying type does not support.

This patch adds smart pointers to be used for initializing objects as C++11
"magic statics" -- that is, they are able to take advantage of C++11's
guarantee of thread safety during initialization by atomically constructing
both the smart pointer itself as well as the object being pointed to.
Unlike Static{Auto,Ref}Ptr, they have non-trivial constructors, though they
must still have trivial destructors to prevent emission of atexit calls.
The new classes use the new `MOZ_STATIC_LOCAL_CLASS` annotation which ensures
their instantiations are static locals and prevents non-trivial destructors.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

This patch addresses both Bug 1551913 and Bug 1552206.
This patches the update directory permission-fixing code.
This also fixes a related bug that I discovered while testing this patch: nsAutoSid doesn't actually work because both PSID and HANDLE are both typedef'ed from void*, so the compiler can't actually tell the difference between them and ends up calling CloseHandle instead of FreeSid. To fix this, I removed nsAutoSid and replaced it with UniqueSidPtr, a UniquePtr type that uses a custom deleter class to free the SID properly.
