Image filters in Skia currently clip the size of the the offscreen
bitmap used for filtering to the device clip bounds. This means that
any pixel-moving filter (e.g., blur) has edge artifacts at the clip
boundaries. This is problematic for tiling, where a single SkPicture
is played back with a clip set to the tile boundaries.
By implementing the onFilterBounds() traversal, and using it in
saveLayer() when a filter is present, we can clip the layer to the
expanded clip rect. Note that this requires that the traversal be
performed in reverse as compared to computeFastBounds(). (It's also
done in device space, unlike computeFastBounds()).
New test imagefiltersclipped tests pixel-moving filters when clipped
by various clip rects.
New test imageblurtiled tests tiled (compositor-style) rendering of
blurred text. There should be no artifacts at the tile boundaries.

Split off from https://codereview.chromium.org/140503007/.
The eventual goal is to create our Android.mk from gyp. This patch
adds an option for skia_android_framework with the right settings.
The follow-up (https://codereview.chromium.org/140503007/) will
use scripts to create the final makefile.
gyp/android_deps.gyp:
Use different dependencies for the framework than for building Skia
normally.
gyp/android_framework_lib.gyp:
Like skia_lib, specifies the minimum needed for building Skia, in this
case for the framework.
gyp/common_conditions.gypi:
Add settings specific to skia_android_framework. In some cases this
means turning off flags and defines.
gyp/common.gypi
Turn off SK_DEBUG and SK_DEVELOPER when building for the framework.
This allows the framework to create a single makefile which can be
modified to add SK_DEBUG and SK_DEVELOPER as desired.
gyp/common_variables.gypi:
Add skia_android_framework.
gyp/core.gyp:
Don't depend on cpufeatures, and add the cutils library for
skia_android_framework.
gyp/freetype.gyp:
skia_android_framework-specific options:
Don't include freetype_static as a dependency.
Include the proper folders.
Include the android library.
gyp/images.gyp:
Don't export libjpeg as a dependency for targets that include images
for the framework.
Also reorder image decoders to match the Android order, leaving our
most commonly used ones last (and therefore first in the chain for
trying them).
gyp/libwebp.gyp:
Use the system webp when building for the Android framework. Specify
the correct settings for the framework.
gyp/opts.gyp:
Specify a default set of files to compile when there are no possible
optimizations.
gyp/pdf.gyp:
Add dependencies for Android framework.
gyp/zlib.gyp:
Include the zlib folder, and undefine SK_ZLIB_INCLUDE.

This patch includes a modified version of Chrome's trace_event.h, which provides
tracing macros that can easily integrate into the about://tracing framework.
Currently the macros link to a default implementation of the (narrow) tracing
class SkDefaultEventTracer which does nothing; next step will be to have Chrome
subclass the SkEventTracer with a shim that bolts Skia's trace events to its own,
allowing Skia's trace events to show up in about://tracing.
I've verified that this file builds properly, and when I added a simple scoped
TRACE_EVENT0 to SkCanvas::drawRect, along with some debug prints in the NOP
implementation of tracing, I saw what I expected printed to the screen.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.
What used to be this:
SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer
is now
SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer
Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed
This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.

BitmapProcState: new factorised code
This one basically factorises the clamp and repeat transformations with
some performance improvements. It has the benefit of being faster, much
easier to maintain (nearly three times less code for more work
done :-)), and more complete (all persp transformations weren't optimised
in the previous version).
It also introduces the use of can_truncate_to_fixed_for_decal where
useful.
The effect on benchmarks ranges from a 5% penalty to a 25% gain on a
Cortex-A9 and from a 5% penalty to a 100% gain on a Cortex-A15.

This revealed that the displacement map was not handling clipping or upstream cropping at all well (the color would "swim" through the displacement at the edge of the clip rect). Fixed by passing through the correct offsets to the bitmap accesses in both raster and GPU paths. Same for morphology.

Make leak counters implemented with SK_DECLARE_INST_COUNT thread-safe.
Enable the leak counting for Debug builds when Skia is built as a
static library. Having SK_DECLARE_INST_COUNT without
SK_DEFINE_INST_COUNT relies on static variables in member functions
declared in the header files. These might be duplicated in the clients
of the library when Skia is built as a dynamic library, producing
incorrect operation.
Protect the instance counter initialization step (initStep) by
using SkOnce.
Makes SkOnce.h part of the public API, since SkInstCnt is public.
Protect the per-class child list shared variable with a per-class mutex.
Changes the behavior in the way that if the child list has been
"cleaned up", it will still try to create subsequent child lists.
