The option allows to iterate on the allocator code without requiring a
complete setup to build Firefox.

This is a hack that was added back when the chromium ipc codebase was
imported, but that shouldn't be required anymore. The mozalloc operator
new is gotten through stl wrapping these days.

Bug 1417309 - Move some definitions from top-level moz.build to application-specific moz.build files. r=nalexander

When building with a --enable-project that is neither js nor a
toolkit-based one (like browser or mobile/android), we don't want to be
building things that are specific to gecko and/or spidermonkey.

At the same time, this lifts the exception that js standalone doesn't
have an app.mozbuild included, and makes the moz.build parsers that
don't set a MOZ_BUILD_APP get the same information as they were through
toolkit.mozbuild.

We still keep mfbt, build and a few other DIRS set from the top-level,
because at the moment, there aren't really any --enable-project that
would benefit from those not being recursed.

bug 1407562 - Fix in-content HTML selects and about:telemetry "Raw JSON" element for RTL locales r=chutten

The arrow icon in about:telemetry's process <select> overlapped the text in RTL.
It turns out that this was also a problem in a couple of other places in the UI,
including the Add New Credit Card and And New Address dialogs for form autofill.
Now, those are fixed too.

On the about:telemetry page, the "Raw JSON" element is in the appropriate place now.
Earlier it was on the left in RTL locales.

Bug 1325632 - part 5 - ensure that we compile with -fno-sized-deallocation when possible; r=chmanchester

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.

We have code to test whether particular flags are supported for the
compiler we're using.  Unfortunately, that code is tied up with checking
for warning flags.  We're about to add a separate facility for generic
compilation flags, and we'd like to avoid cutting and pasting code if
possible.  Let's split the core code out into a separate, reusable function.

This probably doesn't make a huge difference, as we're not generating
any code here, but better safe than sorry.

We're going to compile with C++14 and we don't plan to go back.

This was needed before as the base to nsGlobalWindow, but now that
nsGlobalWindow doesn't exist, and we only have specific versions, we no longer
need this type.

There are many helper methods and structs in nsGlobalWindow.cpp. Many of these
are used by only the inner or only the outer window, while some are used by
both. In the case of the items used by both, I extracted them into
nsGlobalWindow.cpp, which includes nsGlobalWindowInner.cpp and
nsGlobalWindowOuter.cpp as the compilation unit entry point.

In the case of items used by just one or the other, I removed them from the
other file, and deleted the bodies of functions which used them, replacing them,
with a MOZ_CRASH.

This gets gecko building again, so that we can make further incremental
improvements.
