This MOZ_CRASH() is redundant after calling noreturn function mozalloc_abort. The MOZ_ASSUME_UNREACHABLE_MARKER() annotation makes ARM's "function declared 'noreturn' should not return" warnings go away.

Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.
This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

I don't know why this isn't a problem currently, but it becomes one with
the #include orders in some of the source files in mozglue/linker, where
the compiler complains about the allocator functions being defined
differently wrt exceptions if they are defined via malloc_decls before
cstdlib/stdlib.h is included.

glibc marks various allocation functions as `throw()`. This addition
hasn't been a problem until we tried to enable C++17, where clang
started complaining that we were redeclaring functions with mismatched
exception specifications. Peculiarly, glibc declares virtually
everything we redeclare as `throw()`, but clang only complains about the
mismatches for a particular subset of functions.
The approach taken in this patch is to add another potentially defined
macro to malloc_decls.h, `NOTHROW_MALLOC_DECL`. This macro works
exactly like `MALLOC_DECL`, except that clients can define
`NOTHROW_MALLOC_DECL` to add appropriate `throw()` specifiers when
declaring functions at global scope, and thereby avoid mismatched
exception specifications.

In the MinGW build, calls to malloc inside mozglue were not being
redirected as defined in the .def file. We create aliases for the
redirected functions to correctly redirect them inside mozglue.
An alternate solution for this exists. Rather than creating the
importlib during the linking step for mozglue, we could have used
dlltool to create it, and then provided it during linking. This
would allow mozglue to know that it should redirect calls to malloc
to je_malloc as specified in the .def file.

- On Android, we were already doing it, but using fallible allocations.
- On *nix, it probably doesn't make a difference, but can't hurt. For
most things in Gecko, operator new/delete are inlined and thus
replaced by direct calls to the underlying allocator functions
(moz_xmalloc, malloc, etc.). This may have a benefit for some third
party libraries that would otherwise go through libstdc++'s to
eventually end up back into our allocator via the zone allocator
on macOS and via the exported symbols on others.
- On Windows, because of how some CRT static libraries are, a non-inlined
operator new (thanks to some disabled STL wrapping) would end up linked
against the system malloc, causing problems.
Overall, this can only be better. This also reduces the number of places
where we define those functions.
And on Android, this means operator new within mozglue becomes infallible,
which is more consistent with everything else.

The current situation is suboptimal, where we have the same goop
repeated in multiple files, and where things kinda sorta work out fine
thanks to the linker for files that would have been forbidden, except
when the linker doesn't do its job, which apparently happen on
mingwclang builds.
This change only really covers C++ code using operator new/delete, and
not things that would be using malloc/free, because it's easier.
malloc/free is left for a followup.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
- modify line wrap up to 80 chars; (tw=80)
- modify size of tab to 2 chars everywhere; (sts=2, sw=2)

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.
