At the same time, remove the MOZ_STATIC_ASSERT_VALID_ARG_COUNT, which
doesn't actually work for more than 50 arguments(*), and which is now not
useful to detect 0 arguments.
(*) the build fails, but not directly thanks to the static_assert it
expands to.

Add breakpoint support for AArch64, and fix a scanf format specifier
warning. Also fix an #if line in xptcinvoke_arm.cpp to work as intended.

This annotates vsprintf-like functions with MOZ_FORMAT_PRINTF. This may
provide some minimal checking of such calls (the GCC docs say that it
checks for the string for "consistency"); but in any case shouldn't
hurt.

See also bug 1361495 - PR_SI_HOSTNAME is implemented in NSPR on
Windows as initializing winsock which can be janky. There don't seem
to be any users of this property, and it has tracker concerns anyhow -
so remove it.

When we just had CycleCollectedJSContext (and no CycleCollectedJSRuntime) a
weird thing happened at shutdown:
1. We would call JS_DestroyContext from ~CycleCollectedJSContext. By that time,
the ~XPCJSContext destructor had already finished.
2. Destroying the context runs a final GC. That GC would call back into various
GC callbacks, such as TraceBlackJS and TraceGrayJS.
3. These callbacks would do a virtual method call:
http://searchfox.org/mozilla-central/rev/876c7dd30586f9c6f9c99ef7444f2d73c7acfe7c/xpcom/base/CycleCollectedJSRuntime.cpp#791
4. Normally this method call would call into
XPCContext::TraceNativeBlackRoots. However, C++ changes the vtable for an
object during destruction. So we would only call CycleCollectedJSContext's
version of TraceNativeBlackRoots, which is empty. So we never traced anything.
When I moved this code into the runtime, we actually do call into
XPCJSRuntime::TraceNativeBlackRoots at that time. So the behavior changed, and
that was causing crashes once I nulled out the TLS as you asked. So I removed
these callbacks for the last GC.

This patch keeps a list of all the cooperatively scheduled contexts that are
linked to a runtime. In places where we need to iterate over all contexts (for
GC, specifically), it iterates over the list.

This change moves most of the logic for the threadsafety check into
nsAutoOwningThread, rather than having part of the logic live in
nsAutoOwningThread and part of the logic live in nsDebug.h. Changing
this also forces us to clean up a couple of places that replicated the
logic that lived in nsDebug.h as well.
Change mozilla::Smprintf and friends to return a UniquePtr, rather than
relying on manual memory management. (Though after this patch there are
still a handful of spots needing SmprintfFree.)

To run JS in separate cooperative threads, we need to split up per-thread state
from per-runtime state. This patch does that for XPConnect.

This patch makes the error codes in nsError.h be generated by a python script.
This gives us the opportunity to add rust code generation in parallel with the
C++ code generation, which will happen in part 2.
This patch also reworks the name calculation in ErrorNames.cpp to use generated
code by the python script.

This uses std::atomic rather than mozilla::Atomic since mozilla::Atomic
does not support using different memory synchronization for different
atomic operations on the same variable.
The added comments could use careful review since, while they reflect my
understanding of the issue, I don't consider myself an expert on the
topic.

For testing purposes it will be useful to be able to trigger crashes in Rust
code. Being able to trigger a panic seems like a good place to start. This
will make it easier to validate improvements in crash reporting.
