Multiple Master and TrueType fonts support variation axes.
This implements back-end support for axes on platforms which
support it.

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.

Fixed a few issues while attempting to use the new
serialization path for SkPicture inside a fuzzer:
- SkReadBuffer and SkValidatingReadBuffer both had a fReader
member instead of sharing the same member, which leads to
problems if a base class function is used
- In SkPicture, a header is now written as a single chunk of
data, so it also has to be read as a single chunk of data
- In the SkPicturePlayback destructor, a bad deserialization
would lead to a crash if we don't safely unref fOpData
- Also in SkPicturePlayback, if we only use a ReadBuffer for
the whole deserialization, additional tags must be added to
parseBufferTag()
- SkValidatingReadBuffer::readBitmap() was broken, but this
path wasn't usen't since the only use case for
SkValidatingReadBuffer is currently image filters and
bitmaps are unflattened as part of the deserialization of
SkBitmapSource
- SkPictureImageFilter was not deserializable. Added it to
SkGlobalInitialization*
- Added a test that exercises the SkPicture serialization /
deserialization code

This is a baby step toward refactored (and faster in-process) typeface and flattenable factory encoding and decoding. The sooner SkWriteBuffer knows its flags, the better.
Next steps will be to rearrange Sk{Read,Write}Buffer members into disjoint strategies to handle typefaces and flattenable factories: one for in-process, one for cross-process, one when validating.

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.

This reduces the allocation overhead of a null picture (create, beginRecording(), endRecording) from about 18K to about 1.9K. (There's still lots more to prune.)
SkPictureFlat can exploit the fact that Writer32 is contiguous simplify its memory management. The Writer32 itself becomes the scratch buffer.
Remove lots and lots of arbitrary magic numbers that were size guesses and minimum allocation sizes. Keep your eyes open for the big obvious DUH why we save 16K per picture! (Spoiler alert. It's because that first save we issue in beginRecording() forces the old SkWriter32 to allocate 16K.)
Tests passing, DM passing.
bench --match writer: ~20% faster
null bench_record: ~30% faster
bench_record on buildbot .skps: ~3-6% slower, ranging 25% faster to 20% slower
bench_pictures on buildbot .skps: ~1-2% faster, ranging 13% faster to 28% slower

Revert "Revert "PixelRef now returns (nearly) everything that is currently in SkBitmap. The goal is to refactor bitmap later to remove redundancy, and more interestingly, remove the chance for a disconnect between the actual (pixelref) rowbytes and config, and the one claimed by the bitmap.""""""
