We're currently using NDK r15c, which is rather old, and happens to come
with a buggy gold linker. Let's use a more recent NDK, with a fixed
linker.
Unfortunately, we're currently at NDK API level 9, which the newer NDK
doesn't provide for x86 anymore. But that corresponds to Gingerbread
(2.3), which we've long stopped supporting. On the SDK side, we already
dropped support of versions before Jelly Bean, so we can do the same on
the NDK side. That corresponds to API level 16. So let's just use that
as a baseline.
Another change in the newer NDK is that the target-name changed from
i386-linux-android to i686-linux-android, so adjust for that in the
android x86 mozconfigs.
Bug 1280578 added some wrapping for the Win32 Heap* functions, mainly
for the rust static libraries that use them. Because pointer ownership
might cross the C++/Rust boundary, and because about:memory uses
malloc_usable_size/msize, we need both C++ and Rust to still use the
same heap on builds where our allocator is not enabled.

The std::nothrow variant of operator new is effectively a fallible
operator new. It is used in third party code.
The duplication with our own fallible operator new is unfortunate, and
we can reduce it by making one an alias of the other.
We keep the fallible library as a dummy on Android because bug 1423802
induces some linking problems.

Bug 1163171 removed support for building for android with GCC, and we
don't need to use throw() anymore. We can use the same code as for other
non-Windows platforms.

MOZ_ALWAYS_INLINE_EVEN_DEBUG is always defined through
mozilla/Attributes.h, so the fallbacks are never used in practice. They
are just there from the old days when mozalloc.h didn't use
mozilla/Attributes.h.

They are both infallible wrappers of posix_memalign and valloc.
There is also moz_xmemalign, which wraps memalign, which is mostly
always available as of bug 1402647.
None of them are actually used, but it's still desirable to at least
have one infallible variant, so keep moz_xmemalign and remove the other
two.
While here, we actually make both memalign and moz_xmemalign always
available.

When this was added, the xpcom glue was still a thing, and there was a
distinction between things that would build with mozalloc available and
others. There is no such distinction anymore. Anything that has access
to xpcom has access to infallible allocator functions.

We currently turn off the C++14 sized-deallocation facility on MSVC, and
we'd like to ensure we do the same thing for clang and gcc. To do so,
we add new functionality to moz.configure for checking and adding
compilation flags, similar to the facility for checking and adding
warning flags. The newly added facility is then used to add
-fno-sized-deallocation to the compilation flags, when the option is
supported.
Once we do this, we can't define the sized deallocation functions in
mozalloc.h; the compiler will complain that we are using
-fno-sized-deallocation, yet defining these special functions that we'll
never use. These functions were added for MinGW, where we needed to
compile with C++14 ahead of other platforms to be compatible with MSVC
headers. But they're no longer necessary, though they would be if we
removed -fno-sized-deallocation; the compiler will complain if we do
that and we'll add them back at that point.
mozalloc_abort is not marked as a noreturn function on ARM, so clang
complains when abort calls mozalloc_abort, which calls MOZ_CRASH, which
calls abort(). We know this is OK, so just disable the warning.
jemalloc_ptr_info() gives info about any pointer, such as whether it's within a
live or free allocation, and if so, info about that allocation. It's useful for
debugging.
moz_malloc_enclosing_size_of() uses jemalloc_ptr_info() to measure the size of
an allocation from an interior pointer. It's useful for memory reporting,
especially for Rust code.

This avoids many additions of `extern "C"` in C++ code and will avoid
having to do the same to mozjemalloc once built as C++.
