Pretty vanilla translation. I cleaned up who calls whom a little.
Used to be utils -> opts -> utils, now it's just utils -> opts.
I may follow up with a pass over the NEON code for readability
and to clean up dead code.
This turns on NEON A8->R11EAC conversion for ARMv8.
Unit tests which now hit the NEON code still pass.
I can't find any related bench.

Traditionally, SkTraceEvent.h was manually kept in sync with base/trace_event/trace_event.h, with project-specific parts intermixed, and tended to drift out of sync a lot (mainly in Blink, less so in Skia).
The SkTraceEventCommon.h now has only the cross-project parts, and can be copy-pasted verbatim between projects (it's an identical copy of base/trace_event/trace_event_common.h), meaning SkTraceEvent.h shouldn't go out of sync as it has before.

Nothing too fancy.
Direction enums become enum classes so they don't get all confused. An
alternative is to create one single Direction enum that both blur and
morphology opts use.

Motivation: maintaining this code doesn't seem worth the time,
since no one seems to be using it. If someone wants to use it
in the future, just revert this CL.

Prior to this CL, if a client wanted to decode scanlines, they had to
create an SkCodec in order to get an SkScanlineDecoder. This introduces
complications if input data is not easily shared between the two
objects.
Instead, add methods to SkScanlineDecoder for creating a new one from
input data, and remove the creation functions from SkCodec.
Update DM and tests.

I also rearranged the code a little bit to encapsulate itself better,
mostly replacing static helper functions with lambdas. This also
let me merge the SSE2 and SSE4.1 code paths.

Renames Sk4pxXfermode.h to SkXfermode_opts.h,
and refactors it a tiny bit internally.
This moves xfermode optimization from being "compile-time everywhere but NEON"
to simply "runtime everywhere". I don't anticipate any effect on perf or
correctness.

With this new arrangement, the benefits of inlining sk_memset16/32 have changed.
On x86, they're not significantly different, except for small N<=10 where the inlined code is significantly slower.
On ARMv7 with NEON, our custom code is still significantly faster for N>10 (up to 2x faster). For small N<=10 inlining is still significantly faster.
On ARMv7 without NEON, our custom code is still ridiculously faster (up to 10x) than inlining for N>10, though for small N<=10 inlining is still a little faster.
We were not using the NEON memset16 and memset32 procs on ARMv8. At first blush, that seems to be an oversight, but if so it's an extremely lucky one. The ARMv8 code generation for our memset16/32 procs is total garbage, leaving those methods ~8x slower than just inlining the memset, using the compiler's autovectorization.
So, no need to inline any more on x86, and still inline for N<=10 on ARMv7. Always inline for ARMv8.

SDL isn't an OS anyway, it's just a library views can use. Remaining

There is more than one way to skin this SkPathPriv.h cat.
These constructors are large enough that they probably shouldn't have

I'll be moving headers from src/core to include/private, so this guarantees
that anyone who was finding them via -Isrc/core can now find them via
-Iinclude/private.
This is purely mechanical, mostly to preserve my sanity, so it's likely
(harmless) overkill.
Chromium's GYP and GN builds already set -Iinclude/private for Skia builds.

The Android framework was failing on conditions in

If we ever want to allow the command buffer as a skia gles2 backend,
we need a more up to date version of ANGLE, specifically there are
4 defines that differ between newer and older versions of ANGLE which
we use in skia, I've updated these in this change.
I'm not quite sure if what I've done for the 'angle_path' is correct,
I tried setting it to a path relative to skia, and to '<(DEPTH)', both
of which do not compile correctly, only '../' worked.

Visual Studio 2015 has additional warnings around noexcept and
disabling exceptions, which can be worked around with the
(undocumented) _HAS_EXCEPTIONS macro.
Visual Studio 2013 and 2015 have roundf in math.h, so use it to
avoid extra work and casts.
We avoid using cmath, as it undefs isfinite on gcc, but Visual Studio
2015 no longer provides overloads of copysign from math.h (which is
actually correct). As a result, use copysignf (which is available in
math.h in 2013 and 2015) directly.

It turns out that gyp (kind of) has support for cross
compiling with a different host and target. We simply
need to specify CC_host and CC_target instead of CC.
Making this change allows us to compile yasm on a Linux
host for Android.
We run into problems on Mac because
the linker on a Mac host requires different command line
arguments than the linker on the Android target. In
looking through the code for gyp itself and speaking to
Ben, it doesn't appear to me that gyp supports passing
different arguments to host and target linkers.
I would imagine that we would have similar problems on
Windows.
Below is a link to a CL that would fix this issue in gyp.
It looks like it has been dropped for a long time.
Thanks to Ben for this link!

Also I'm adding a link to the build instructions for Chrome
(thanks again Ben). It looks like they only support
building for Android from Linux.
https://code.google.com/p/chromium/wiki/AndroidBuildInstructions
My next steps are:
1) Getting in touch with Torne or someone else with gyp to
see if people are aware of this issue or interested in
fixing it.
2) Deciding if skia should care about this issue.
3) Deciding if skia should work around this issue.
It'd be really great to hear your thoughts on (2) and (3).
My first thought is that we shouldn't care because, as
long as we always compile the production copy of skia for
Android on Linux, we will get the fast code. Is this
a valid conclusion? Is there a way to write Android apps
on Mac that accidentally use the slower code?
If we do care, there are workarounds:
For Mac, we can check in a yasm binary - it's a little
smaller than the one I am deleting in this CL :-/
For Windows, we *might* be able to use the yasm.exe binary
already in externals (we get this from DEPS because this is
how chromium uses yasm on Windows).
Are there other platforms that we care about?
Let me know what you think!

There is nothing left in the SkFontMgr_android.cpp which is specific
to Android, so allow it to be built and used on *nix platforms. This
allows for easier development and testing.
The only reason to limit to *nix platforms are the dependencies on
Expat and FreeType. This should be buildable and runnable on other
platforms when these dependencies are also available.
