Implementing filling for SkBmpCodec
The bmp codec currently returns kIncompleteInput
when the stream is truncated, which we treat as a
partial success. However, we neglect the fill the
remaining pixels in the image, leaving these
uninitialized.
This CL addresses this problem by initializing the
remaining pixels in the image to default values.

***Disables swizzles to 565.
We may want to enable swizzles to 565
for images that are encoded in a format
similar to 565, however, we do not want
to take images that decode naturally to
kN32 and then convert them to 565.
***Enable swizzles to kIndex_8. For images
encoded in a color table format, we suggest
that they be decoded to kIndex_8. When we
decode, we only allow conversion to kIndex_8
if it matches the suggested color type (except
wbmp which seems good as is).
***Modify dm to test images that decode to
kIndex_8.

Add scanline decoding to SkCodec.
Add an interface for decoding scanlines, and implement that interface
in the PNG decoder.
Use a separate method to determine whether an image that used a type
with alpha was actually opaque.
SkScanlineDecoder.h:
New interface for decoding scanlines.
SkCodec.h:
Add getScanlineDecoder.
Add a virtual function (with non-virtual caller) for determining
whether the image truly had alpha. The client can call this to
determine if the image was actually opaque if it reported having alpha.
Remove code to sneakily change the passed in alpha type.
SkCodec_libpng.*:
Split up code onGetPixels into helper functions that can be shared with
the scanline decoder.
Implement scanline decoding.
Implement onReallyHasAlpha.
SkSwizzler.*:
Add a new SrcConfig as a default, which is invalid.
Add a function for setting fDstRow directly.
Assert fDstRow is not NULL.

Adding swizzles for bmp:
We now support kN32 and kRGB_565 color types.
Additionally, we support premul, unpremul, and opaque alpha types.
Unpremul is currently untested as we cannot currently draw to unpremul.

Add SkCodec, including PNG implementation.
DM:
Add a flag to use SkCodec instead of SkImageDecoder.
SkCodec:
Base class for codecs, allowing creation from an SkStream or an SkData.
An SkCodec, on creation, knows properties of the data like its width and height. Further calls can be used to generate the image.
TODO: Add scanline iterator
SkPngCodec:
New decoder for png. Wraps libpng. The code has been repurposed from SkImageDecoder_libpng.
TODO: Handle other destination colortypes
TODO: Substitute the transpose color
TODO: Allow silencing warnings
TODO: Use RGB instead of filler?
TODO: sRGB
SkSwizzler:
Simplified version of SkScaledSampler. Unlike the sampler, this object does no sampling.
TODO: Implement other swizzles.
Requires a gclient sync to pull down libpng.
