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.

JSONWriter currently calls new and delete indirectly through mozilla::MakeUnique to allocate a buffer. Becuase of this, the methods of this class cannot be invoked within Spidermonkey due to https://searchfox.org/mozilla-central/source/config/check_vanilla_allocations.py#6-14. Therefore, JSONWriter needs an AllocPolicy template parameter so that the allocation and deallocation routines can be changed to match the JS AllocPolicy when invoked within SpiderMonkey.

Entry storage allocation now occurs on the first lookupForAdd()/put()/putNew().
This removes the need for init() and initialized(), and matches how
PLDHashTable/nsTHashtable work. It also removes the need for init() functions
in a lot of types that are built on top of mozilla::Hash{Map,Set}.
Pros:
- No need for init() calls and subsequent checks.
- No memory allocated for empty tables, which are not that uncommon.
Cons:
- An extra branch in lookup() and lookupForAdd(), but not in put()/putNew(),
because the existing checkOverloaded() can handle it.
Specifics:
- Construction now can take a length parameter.
- init() is removed. Explicit length-setting, when necessary, now occurs in the
constructors.
- initialized() is removed.
- capacity() now returns zero when the entry storage is absent.
- lookupForAdd() is no longer `const`, because it can instantiate the storage,
which requires modifications.
- lookupForAdd() can now return an invalid AddPtr in two cases:
- old: hashing failure (due to OOM in the hasher)
- new: OOM while instantiating entry storage
The existing failure handling paths for the old case work for the new case.
- clear(), finish(), and clearAndShrink() are replaced by clear(), compact(),
and reserve(). The old compactIfUnderloaded() is also removed.
- Capacity computation code is now in its own functions, bestCapacity() and
hashShift(). setTableSizeLog2() is removed.
- uint32_t is used throughout for capacities, instead of size_t, for
consistency with other similar values.
- changeTableSize() now takes a capacity instead of a deltaLog2, and it can now
handle !mTable.
Measurements:
- Total source code size is reduced by over 900 lines. Also, lots of existing
lines got shorter (i.e. two checks were reduced to one).
- Executable size barely changed, down by 2 KiB on Linux64. The extra branches
are compensated for by the lack of init() calls.
- Speed changed negligibly. The instruction count for Bench_Cpp_MozHash
increased from 2.84 billion to 2.89 billion but any execution time change was
well below noise.
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.
