Revert of Make SkPngCodec decode progressively. (patchset #26 id:520001 of https://codereview.chromium.org/1997703003/ )
Reason for revert:
Still causing problems in Google3, e.g.
https://test.corp.google.com/ui#cl=124138817&flags=CAMQBQ==&id=OCL:124138817:BASE:124139560:1465227435491:219ffbdb&t=//third_party/skia/HEAD:dm
Original issue's description:
> Make SkPngCodec decode progressively.
>
> This is a step towards using SkCodec in Chromium, where progressive
> decoding is necessary.
>
> Switch from using png_read_row (which expects all the data to be
> available) to png_process_data, which uses callbacks when rows are
> available.
>
> Create a new API for SkCodec, which supports progressive decoding and
> scanline decoding. Future changes will switch the other clients off of
> startScanlineDecode and get/skip-Scanlines to the new API.
>
> Remove SkCodec::kNone_ScanlineOrder, which was only used for interlaced
> PNG images. In the new API, interlaced PNG fits kTopDown. Also remove
> updateCurrScanline(), which was only used by the old implementation for
> interlaced PNG.
>
> DMSrcSink:
> - In CodecSrc::kScanline_Mode, use the new method for scanline decoding
> for the supported formats (just PNG and PNG-in-ICO for now).
>
> fuzz.cpp:
> - Remove reference to kNone_ScanlineOrder
>
> SkCodec:
> - Add new APIs:
> - startIncrementalDecode
> - incrementalDecode
> - Remove kNone_SkScanlineOrder and updateCurrScanline()
>
> SkPngCodec:
> - Implement new APIs
> - Switch from sk_read_fn/png_read_row etc to png_process_data
> - Expand AutoCleanPng's role to decode the header and create the
> SkPngCodec
> - Make the interlaced PNG decoder report how many lines were
> initialized during an incomplete decode
> - Make initializeSwizzler return a bool instead of an SkCodec::Result
> (It only returned kSuccess or kInvalidInput anyway)
>
> SkIcoCodec:
> - Implement the new APIs; supported for PNG in ICO
>
> SkSampledCodec:
> - Call the new method for decoding scanlines, and fall back to the old
> method if the new version is unimplemented
> - Remove references to kNone_SkScanlineOrder
>
> tests/CodecPartial:
> - Add a test which decodes part of an image, then finishes the decode,
> and compares it to the straightforward method
>
> tests/CodecTest:
> - Add a test which decodes all scanlines using the new method
> - Repurpose the Codec_stripes test to decode using the new method in
> sections rather than all at once
> - In the method check(), add a parameter for whether the image supports
> the new method of scanline decoding, and be explicit about whether an
> image supports incomplete
> - Test incomplete PNG decodes. We should have been doing it anyway for
> non-interlaced (except for an image that is too small - one row), but
> the new method supports interlaced incomplete as well
> - Make test_invalid_parameters test the new method
> - Add a test to ensure that it's safe to fall back to scanline decoding without
> rewinding
>
> BUG=skia:4211
>
> The new version was generally faster than the old version (but not significantly so).
