(This is essentially a revert of https://codereview.chromium.org/503833002/.)
This was necessary back when SkPaint was flattened even for in-process use. Now that we only flatten SkPaint for cross-process use, there's no need to serialize UniqueIDs.
Note: SkDropShadowImageFilter is being constructed with a croprect and UniqueID (of 0) in Blink. I've made the uniqueID param default to 0 temporarily, until this rolls in and Blink can be changed. (Blink can't be changed first, since unlike the other filters, there's no constructor that takes a cropRect but not a uniqueID.)

Unprotected reads -> relaxed reads.
Unprotected write -> relaxed write.
The only unprotected write we had was in SkTraceEvent, which it looks like we nabbed from Chrome at some point and changed only to silence TSAN. Chrome's version uses AtomicWord / NoBarrier_Load / NoBarrier_Store, which boils down to the same as here, intptr_t / relaxed load / relaxed store.
This leaves one place where we're lying a bit to TSAN, in include/core/SkLazyPtr.h where we're doing a data-dependent consume load. We're telling TSAN it's consume, but telling any other compiler to compile it as relaxed, given how they all upgrade consume to acquire. This eliminates a barrier for us on ARM. How do you guys deal with this? Just use a consume memory order, take the hit, and hope compilers get smarter one day?

A glyph position when mapped from canvas space to device space may land
outside the bounds of the current 16 bit integer part of device space.
Device space is already limited to 32 bits for the integer part,
but for a short space in drawText and drawPosText it is currently
limited to 16 bits (SkFixed). Raise this limit by moving to 48.16.
This matches the current similar fix for measureText.

We've always been using the portable ColorRect32, so we don't need the
ColorRectProc plumbing.
Furthermore, ColorRect32 doesn't seem to be very important (we're only using
it in the opaque case, which our row-by-row procs already specialize for).
Remove that too.
If we find we want specialization for really narrow rects again, let's put it in
blitRect() directly. It's pretty unlikely we're going to get platform-specific
speedup for blits to non-contiguous memory.
My local SKP comparison is +- 3%... most neutral I've ever seen.

Like SkTRacy<T>, TSAN will not complain about these. Unlike SkTRacy<T>, TSAN
should not complain about these: SkAtomic<T> are threadsafe.
This should fix the races now suppressed in TSAN. As written, the memory
barriers we're using in SkPixelRef will be dumb but safe (really, dumbest
possible but safest possible). If we see a perf hit, we can follow up by
putting Ben and I in a room for a while, thinking about it really hard, and
using the minimum-strength safe memory barriers.
A refactor that steals a bit from the genID would also still be possible with
this approach.

SkTHashTable is very similar to SkTDynamicHash, except it's generalized to support non-pointer value types.
It doesn't support remove(), just to keep things simple (it's not hard to add).
Instead of an iterator, it has foreach(), again, to keep things simple.
SkTHashMap<K,V> and SkTHashSet<T> build a friendlier experience on top of SkTHashTable.

No algorithmic changes. The new APIs let us avoid a few ugly trips through void*,
and I've made the consume/acquire/release decision explicitly conditioned on TSAN.
This should fix the attached bug, which is TSAN seeing us implementing the
sk_consume_load() with a relaxed load, where we used to pass __ATOMIC_CONSUME
to TSAN. This restores us to the status quo of a couple weeks ago, where we
use relaxed loads (to avoid an extra dmb on ARM) for all setups except TSAN,
who gets the logically correct memory order, consume.

This adds sk_memory_barrier(), implemented using sk_atomic_fetch_add() on an uninitialized variable. If that becomes a problem we can drop this to the porting layer, using std::atomic_thread_fence() / __atomic_thread_fence() / __sync_synchronize().
The big win is that ref() doesn't generate a memory barrier any more on ARM.
This is an instance of SkSafeRef() in SkPaint(const SkPaint&) after this CL:

4d2: 6018 str r0, [r3, #0]

This merges and refactors SkAtomics.h and SkBarriers.h into SkAtomics.h and
some ports/ implementations. The major new feature is that we can express
memory orders explicitly rather than only through comments.
The porting layer is reduced to four template functions:
- sk_atomic_load
- sk_atomic_store
- sk_atomic_fetch_add
- sk_atomic_compare_exchange
From those four we can reconstruct all our previous sk_atomic_foo.
There are three ports:
- SkAtomics_std: uses C++11 <atomic>, used with MSVC
- SkAtomics_atomic: uses newer GCC/Clang intrinsics, used on not-MSVC where possible
- SkAtomics_sync: uses older GCC/Clang intrinsics, used where SkAtomics_atomic not supported

Decades ago Intel decided that the bsr (Bit Scan Reverse) instruction
should have undefined results if its argument is zero. This probably
makes the instruction harder to implement and it definitely makes it
more difficult to use.
In SkCLZ_portable it requires a check for a zero argument, but despite
that check /analyze still warns that _BitScanReverse might fail
(because it doesn't know what can cause failures). Because this warning
occurs in a frequently included header file it ends up being very noisy,
accounting for ~30% of all warnings (before deduplication).
Suppressing this useless warning will make the raw results easier to
look through.

This method is not called anywhere on Android or Chrome, and it
has a FIXME that it may not be correct.
A client can still getLocalMatrix().isIdentity() if they need this
information. (It has the same FIXME, and perhaps we should revisit
it. In the meantime, this convenience method is not needed.)

SkStream is a stateful object, so it does not make sense for it to have
multiple owners. Make SkStream inherit directly from SkNoncopyable.
Update methods which previously called SkStream::ref() (e.g.
SkImageDecoder::buildTileIndex() and SkFrontBufferedStream::Create(),
which required the existing owners to call SkStream::unref()) to take
ownership of their SkStream parameters and delete when done (including
on failure).
Switch all SkAutoTUnref<SkStream>s to SkAutoTDelete<SkStream>s. In some
cases this means heap allocating streams that were previously stack
allocated.
Respect ownership rules of SkTypeface::CreateFromStream() and
SkImageDecoder::buildTileIndex().
Update the comments for exceptional methods which do not affect the
ownership of their SkStream parameters (e.g.
SkPicture::CreateFromStream() and SkTypeface::Deserialize()) to be
explicit about ownership.
Remove test_stream_life, which tested that buildTileIndex() behaved
correctly when SkStream was a ref counted object. The test does not
make sense now that it is not.
In SkPDFStream, remove the SkMemoryStream member. Instead of using it,
create a new SkMemoryStream to pass to fDataStream (which is now an
SkAutoTDelete).
Make other pdf rasterizers behave like SkPDFDocumentToBitmap.
SkPDFDocumentToBitmap delete the SkStream, so do the same in the
following pdf rasterizers:
SkPopplerRasterizePDF
SkNativeRasterizePDF
SkNoRasterizePDF
Requires a change to Android, which currently treats SkStreams as ref
counted objects.

This code requires fewer macros to use it (just one), has less code in macro
definitions, and has simpler synchronization code (just atomic ints, no SkOnce,
no SkMutex, etc.)
A minor downside, we lose indentation and reverse-ordering in the final report:

This is motivated by wanting to land https://codereview.chromium.org/806473006/,

There are only a handful of SkFlattenables that are not flattenable. That
there are any seems highly illogical. To make this look less like a normal
thing, this removes both macros that marked SkFlattenables as non-flattenable
(in slightly different ways).
The handful of SkFlattenables in our codebase that can't be flattened now
assert violently that they can't be flattened. They're internal or
part of animator... places where we'll never actually flatten them.
TestLooper and DummyRasterizer were so trivial that I just made them flattenable.
