Qualify the return value of SkImageDecoder::decode
Cherry-pick of https://codereview.chromium.org/658343003/ in Skia.
Add a new enum to differentiate between a complete decode and a
partial decode (with the third value being failure). Return this
value from SkImageDecoder::onDecode (in all subclasses, plus
SkImageDecoder_empty) and ::decode.
For convenience, if the enum is treated as a boolean, success and
partial success are both considered true.
Note that the static helper functions (DecodeFile etc) still return
true and false (for one thing, this allows us to continue to use
SkImageDecoder::DecodeMemory as an SkPicture::InstallPixelRefProc in
SkPicture::CreateFromStream).
Also correctly report failure in SkASTCImageDecoder::onDecode when
SkTextureCompressor::DecompressBufferFromFormat fails.

Image decoder fixes (mostly) around A8.
Opaquness:
When decoding Gray to A8 in libpng, set reallyHasAlpha to true
and add a comment why we do not check for the real answer.
Add comments in jpeg decoder explaining why A8 is not opaque.
Fix a bug where an A8 subset is considered to be opaque.
Other fixes:
In SkJPEGImageDecoder, only allocate as much memory as
needed for each source row, based on the input config.
Also pull out common code into a static function.
When performing the check for requiring unpremultiplied colors,
allow A8 to succeed, since that setting should have no effect on
A8.
Add the check for requiring unpremultiplied colors to subset
decoding.
Fix a bug where attempting to sample gray to A8 does not sample.

Add an option on SkImageDecoder to skip writing 0s.
Only implemented for PNG.
Add a getter and setter, and sets the default to false in the
constructor. Also copies the setting in copyFieldsToOther.
Fix an indpendent bug where fDitherImage was not being copied in
copyFieldsToOther.
In SkScaledBitmapSampler::begin, consolidate the settings passed in
by passing a const reference to the decoder. The decoder can be
referenced for its settings of dither, unpremultiplied, and now
skipping writing zeroes. Update callers to use the new API. In png
decoder, rather than passing around a pointer to an initial
read of getDitherImage, and potentially changing it, look at the
field on the decoder itself, and modify it directly. This is a
change in behavior - now if that same decoder is used to decode
a different image, the dither setting has changed. I think this is
okay because A) the typical use case is to use a new decoder for
each decode, B) we do not make any promises that a decode does not
change the decoder and C) it makes the code in SkScaledBitmapSampler
much cleaner.
In SkScaledBitmapScampler, add new row procs for skipping zeroes. Now
that choosing the row proc has five dimensions (src config, dst config,
dither, skip writing zeroes, unpremultiplied), use a new method: each
src/dst combination has a function for choosing the right proc depending
on the decoder.
SkScaledBitmapScampler::RowProc is now public for convenience.
Remove Sample_Gray_D8888_Unpremul, which is effectively no different
from Sample_Gray_D8888.
In cases where unpremultiplied was trivial, such as 565 and when
sampling from gray, decoding may now succeed.
Add a benchmark (currently disabled) for comparing the speed of skipping
writing zeroes versus not skipping. For this particular image, which is
mostly transparent pixels, normal decoding took about 3.6 milliseconds,
while skipping zeroes in the decode took only about 2.5 milliseconds
(this is on a Nexus 4). Presumably it would be slower on an image
with a small amount of transparency, but there will be no slowdown
for an image which reports that it has no transparency.
In SkImageRef_ashmem, always skip writing zeroes, since ashmem
memory is guaranteed to be initialized to 0.
Add a flag to skip writing zeroes in skimage.
Add a regression test for choosing the rowproc to ensure I did not
change any behavior accidentally.

Add an option to create unpremultiplied bitmaps.
Currently they cannot be used directly by Skia, but
the pixels can be used elsewhere.
SkImageDecoder:
Add functions to require unpremultiplied output
and query the presence of the requirement
SkImageDecoder_libpng:
SkImageDecoder_libwebp:
SkImageDecoder_WIC:
Respect the requirement for unpremultiplied output.
TODO: Fix SkImageDecoder_CG.
SkScaledBitmapSampler:
Add procs to skip premultiplication and a boolean
parameter to use those procs.
ImageDecodingTest:
Test unpremultiplied bitmap decoding.
SampleUnpremul:
Add a sample which allows visually comparing between the
unpremultiplied version (copied into a premultiplied bitmap,
since drawing unpremultiplied is not currently supported)
and a premultiplied version of image files.
gm.h:
Add a getter for the resource path, so Samples can use it.
As of patch set 13, https://codereview.chromium.org/16816016/
and https://codereview.chromium.org/16983004/, which were
