Fold alpha to the inner savelayer in savelayer-savelayer-restore
patterns such as this:
SaveLayer (non-opaque)
Save
ClipRect
SaveLayer
Restore
Restore
Restore
Current blink generates these for example for SVG content such as this:
<path style="opacity:0.5 filter:url(#blur_filter)"/>
The outer save layer is due to the opacity and the inner one is due to
blur filter being implemented with picture image filter.
Reduces layers in desk_carsvg.skp testcase from 115 to 78.

I have been hacking at this test trying to understand why the N5 is
still sometimes crashy (it seems, less but not zero now). No luck so far.
But, while I've been reading and hacking at it, I think I've made a
few small improvements, mostly to readability.

This is a speculative fix for the crashing N5 bots. It looks like the bots are
always failing in or around FloatingPointTextureTest.
It looks like sometimes they're hitting a SIGBUS, which I suspect is stack
overflow. FloatingPointTextureTest allocates ~320K on the stack, which may
be too much. This CL moves those buffers to the heap. For consistency I did
the same with the half-float tests, though they're only using ~1/8th the stack.
It looks like sometimes the bots are failing to malloc. I don't understand that,
and this CL doesn't address that directly. But it's possible this is still a stack
overflow, just trashing RAM and causing arbitrary mayhem instead of a SIGBUS.
I have no idea why this is a problem only on the N5. I have been unable to
reproduce this locally, neither with a K N5 nor an L N5, but the bots are pretty
reliable.

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.

Reason for revert:
Our Valgrind bot just spewed out a weird error. I don't know if it's related, but it looks at least like one of the stacks was in the right area, so I'm going to revert this precautionarily. Sorry if this is a false positive.

Scratch key memory buffer of a copy of a key was too big. The (new) copy
was N times uint32_t bytes instead of N bytes.
Adds few tests to resource cache. These tests would not catch the too
big buffer. This is just a precaution for too small buffers. The main
idea of the test change is that the scratch key should contain some
information, so that lookup with a scratch key can also return no
match. Otherwise testing of scratch lookup result is not indicative of
correct code (eg. no-information scratch key will always match).

skiatest::Test class is now a simple struct. Some
functionalty, such as counting errors or timing is now
handled elsewhere.
skiatest:Reporter is now a simpler abstract class. The two
implementations handle test errors.
DM and pathops_unittest updated.

Since only XP's can read dst now, there is no reason to have this query on GrFP.
This also triggered a chain reaction of cleaning up/removing unnecessary code
elsewhere.

Restructure SkGpuDevice creation:
*SkSurfaceProps are optional.
*Use SkSurfaceProps to communicate DF text rather than a flag.
*Tell SkGpuDevice::Create whether RT comes from cache or not.

There's no gyp references to these new files,
so this should only have the effect of reducing

Fold alpha of a save layer call to the subsequent draw call paint, even when
the draw call paint color is already non-opaque.
Comparing the difference of the unoptimized and the optimized call pattern
with all (layer alpha, draw alpha) combinations, this produces
off-by-one pixels ~50% of the time.
Reduces layers of current desk_carsvg.skp (recorded with cross-process
picture image filters allowed) from 122 to 115.

They're only hints. We can ignore them in this optimization.
My only hesitation is that this pattern doesn't seem to happen in our .skps.

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:
Leaked SkRefCntBase: 7
Leaked SkFontMgr: 1
Leaked SkWeakRefCnt: 1
Leaked SkTypeface: 1
Leaked SkFlattenable: 3

This is motivated by wanting to land https://codereview.chromium.org/806473006/,
which makes sure all static use of SkOnce are in global scope. The current
implementation of SkInstCnt uses them in function scope, which isn't safe.

* Add Streamer utility class which measures the current
pdf offset by calling SkWStream::bytesWritten(). Calls
SkPDFCatalog::setFileOffset() and SkPDFObject::emit() at
the same time to guarantee that everything works out.
* SkPDFCatalog::setFileOffset() no longer calculates the
object's size.
* SkPDFCatalog::setSubstituteResourcesOffsets() removed.
* SkPDFCatalog::emitSubstituteResources() removed and
getSubstituteList() made public in its place.
* Remove SkPDFPage::getPageSize and SkPDFPage::emitPage.
Replace with SkPDFPage::getContentStream().
* SkPDFObject::getOutputSize no longer virtual, only used in
unit tests. All SkPDFObject subclasses getOutputSize()
overrides removed.
* SkPDFObject::getIndirectOutputSize removed.
* PDFPrimitivesTest updated for new functions.

Replace virutal SkPDFObject::emitObject(s, c, true) with non-virtual
SkPDFObject::emitIndirectObject(s, c), since none of the subclasses do
(or should do) anything different.
Replace object->emitObject(s, c, false) with object->emitObject(s, c)
This is one step in simplifying the SkPDFObject interface to allow for
the next step in refactoring.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.

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.
