There are use cases for wanting a specific TLS implementation
independently of whether __thread or thread_local are supported.
This is one step in that direction, making the
pthread_{get,set}specific-based implementation available independently.
We still keep everything under the mozilla::detail namespace because
it's still better if people don't try to use mozilla::ThreadLocal
directly.

While the flexibility of the current trait is nice, it's actually not
used to its fullest anywhere, and is boilerplate-y. While it is useful
to be able to put the links anywhere, there's not much usefulness from
being able to split mNext and mPrev.
So instead of a trait that allows to get/set mNext and mPrev
independently, we just use a trait that tells how to get a reference to
a DoublyLinkedListElement from a list element itself.

Also adds a mozilla/ResultExtensions.h header to define the appropriate
conversion functions for nsresult and PRResult. This is in a separate header
since those types are not available in Spidermonkey, and this is the pattern
other *Extensions.h headers follow.
Also removes equivalent NS_TRY macros and WrapNSResult inlines that served the
same purpose in existing code, and are no longer necessary.

nsQueryReferent is defined as an nsCOMPtr_helper, which implies that
calling its operator() method requires a virtual call. While
nsQueryReferent is marked `final`, compiler inlining decisions make it
impossible to de-virtualize the call to operator(). However, we have
many other classes returned by do_* functions that nsCOMPtr handles
directly, requiring no extra virtual calls, and we can give
nsQueryReferent the same treatment.
The generic fallback MOZ_FALLTHROUGH definition is insufficient for GCC 7 and
above, resulting in --enable-warnings-as-errors builds failing.
The check for clang support is changed to use the __has_cpp_attribute macro,
which is more robust than checking the __cplusplus version.
Also, MOZ_FALLTHROUGH is now only defined in C++ code, since GCC errors out if
it encounters a scoped attribute being used with __has_cpp_attribute in C code.
No C code uses MOZ_FALLTHROUGH or derivatives at the moment.

These macros can be used in cases where the `mozilla` namespace might
not refer to the toplevel `mozilla` namespace that was intended. To
ensure that the macros always refer to the `mozilla` namespace in the
global namespace, use the appropriate qualification.
The macro simultaneously declares an enumeration and a count of its
enumerators.
A few variants of the macro are also provided to handle things like
enum classes, underlying types, and enumerations declared at class
scope.

The -fsanitize=integer analysis from UBSan can be helpful to detect signed and unsigned integer overflows in the codebase. Unfortunately, those occur very frequently, making it impossible to test anything with it without the use of a huge blacklist. This patch includes a blacklist that is broad enough to silence everything that would drain performance too much. But even with this blacklist, neither tests nor fuzzing is "clean". We can however in the future combine this with static analysis to limit ourselves to interesting places to look at, or improve the dynamic analysis to omit typical benign overflows.
It also adds another attribute that can be used on functions. It is not used right now because it was initially easier to add things to the compile-time blacklist to get started.
Finally, it includes a runtime suppression list and patches various parts in the test harnesses to support that. It is currently empty and it should not be used on frequent overflows because it is expensive. However, it has the advantage that it can be used to differentiate between signed and unsigned overflows while the compile-time blacklist cannot do that. So it can be used to e.g. silence unsigned integer overflows on a file or function while still reporting signed issues. We can also use this suppression list for any other UBSan related suppressions, should we ever want to use other features from that sanitizer.

I'm not sure how I tested MOZ_FOR_EACH in bug 1368932, but it turns out
it doesn't work with an empty list, despite
MOZ_PASTE_PREFIX_AND_ARG_COUNT now supporting 0 arguments.
Macros can be tricky, and it ends up being easier to make things work
cross-compiler with a separate macro that does the counting, and
(re)building MOZ_PASTE_PREFIX_AND_ARG_COUNT on top of that. Then
MOZ_FOR_EACH ends up working as expected with an empty list.
So this adds a MOZ_ARG_COUNT macro that counts the number of variadic
arguments it's given, and derives MOZ_PASTE_PREFIX_AND_ARG_COUNT from
it.
And this adds a testcase validating that MOZ_FOR_EACH works properly
with an empty list as a result.

Every platform where we use GCC has <atomic>, so there's no need to use
GCC-specific __sync* intrinsics anymore. The <atomic> header may
generate better code for several operations, as well.
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.

On 64-bit Android, the inttypes.h macros for [u]int_fastN_t types (e.g.
int_fast16_t) use "d", "u", etc. as the format specifier, but the types
themselves are defined as `long`, `unsigned long`, etc. This patch
redefines the macros as `PRId64`, `PRIu64`, etc. to provide correct
behavior.
