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.

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.)

It's a very general mechanism for replacing the implementation of
printf_stderr().
It's primarily used by the profiler, sparingly, and not in an important way.
Worse, it prevents us from using MOZ_LOG in the profiler, which is something I
want. Because if any code that locks gPSMutex also calls MOZ_LOG, that then
calls printf_stderr(), which calls profiler_log(), which locks gPSMutex, which
deadlocks.
The only other use of set_stderr_callback() is for the ultra-hacky,
for-local-use-only copy_stderr_to_file() function, which was added for B2G
debugging and is no longer necessary.
This patch removes set_stderr_callback() altogether.

There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.

Bug 1295053 removed most uses of NS_METHOD and NS_CALLBACK, but one use was
unintentionally left behind (in the XPIDL parser) and another has since crept
in (in MediaDrmCDMProxy.h).
So this patch removes NS_METHOD and NS_CALLBACK. NS_METHOD_(nsresult) and
NS_CALLBACK_(nsresult, T) can still be used for the same purpose, but those
alternatives are less likely to be used unintentionally.

NS_LogCOMPtrAddRef and NS_LogCOMPtrRelease always pass false to
GetSerialNumber, because they pass in everything they get without
regard to whether it is being logged or not, so they don't want to
create a serial number if none exists. This causes the assertions
added in bug 1309051 to be hit. To work around this, I hoist the
assertion into the other callers of this method. Two of them already
had this check, but it was non-fatal.
This also makes the asserts not happen in release builds, as I decided
it doesn't really matter what happens if somebody tries to use it
there.

NS_FOUND_TARGET is now declared as an error code. However, making it as a success code makes the code simpler.
First, this patch renames it to NS_SUCCESS_EDITOR_FOUND_TARGET because it's usual naming rule (according to the other declarations).
Next, FindTargetNode() should return it when a nest call of itself returns NS_SUCCESS_EDITOR_FOUND_TARGET as it does now.
Finally, removing the code overwriting NS_FOUND_TARGET with NS_OK from HTMLEditor::CreateDOMFragmentFromPaste() since it doesn't cause hitting NS_ENSURE_SUCCESS() and the variable, rv, will be overwritten with other method's result.
