Through their use of Smprintf, the existing warning message formatting
is resistant to OOM errors. So I figured that we should probably use
something that doesn't infallibly allocate like GetErrorName does.

Also move MOZ_MUST_USE before function declarations' specifiers and return type. While clang and gcc's __attribute__((warn_unused_result)) can appear before, between, or after function specifiers and return types, the [[nodiscard]] attribute must precede the function specifiers.
Also remove MOZ_MUST_USE from nsIMemoryReporter's function pointer typedefs. [[nodiscard]] is an attribute of a function's declaration, not the function's type, and thus can't be applied to function pointers or lambdas.

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.

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.
