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.

MALLOC_STATIC_PAGESIZE is only set on some platforms. Specifically, it's
not set on ia64 and sparc. Which means the case MALLOC_STATIC_PAGESIZE
&& (sparc || ia64) never happens, and gPageSize is never 8 KiB.

In D25711, I added an arenaId member to `jemalloc_ptr_info_t` when `MOZ_DEBUG`
is defined. This modifies the GTest for `jemalloc_ptr_info()` to ensure that
the new member returns the correct value.

To ensure that any new JSString has its char buffer allocated in the new arena,
it is useful to be able to query a pointer and assert that it is in the
correct arena (at-least in Debug Build).
This adds the required functionality to mozjemalloc, and JSString can use it
for its new assertion in a later change.

Changes:
- most tests are skipped using `moz.build` configuration file.
- `MultiWriterQueue` had to be skipped with `define` clauses in the test file due to build bustages when its `moz.build` file was used.

This doesn't change behaviour because `sizeof(uintptr_t)` equals
`sizeof(uintptr_t*)`, but it's good to make things more obviously correct.

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.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

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.
The diagnostic assert (so fortunately, it doesn't impact release builds)
as added in bug 1405159, but is costly because it uses the modulus of
the division with a variable integer, which is a slow operation.
However, in arena_run_reg_dalloc, we end up doing the same diagnostic
assert, in a different form: after performing the division in a faster
manner, we assert that the result, multiplied by the diviser, returns
the original number.

Previously the id for a new arena was just a counter that increased by one
every time. For hardening purposes, we want to make private arenas use a secure
random ID, so an attacker will have a more difficult time finding the memory
they are looking for.
