Original change's description:
> SkJpegCodec: Add SkJpegSourceMgr
> The current skjpeg_source_mgr (in SkJpegUtility.cpp/h) is effectively
> two implementations (buffered vs in-memory) controlled via if
> statements.
> Turn these into two implementations of a pure virtual interface
> SkJpegSourceMgr. The reason for this it that there will be a third
> interface added for buffered non-seekable sources (which will
> run an SkJpegSegmentScanner on the data as it is read).
> Leave the pre-existing skjpeg_source_mgr in place because it may
> be used in other places. It will be removed separately.
