The Res_png_9patch struct had several pointer members whose size differed between 32 and 64 bit platforms. These members have been replaced by uint32_t offsets to serialized data. The serialized form for 9patches places a Res_png_9patch object at the beginning of serialized data, followed by int32_t arrays of xDivs, yDivs and colors. Note that these offsets are not strictly required, since they can be computed from the values of numXDivs, numYDivs & numColors, however they are called in tight loops so having them computed once is a beneficial. This change also removed the unused patch_equals function from aapt's Image.cpp. Change-Id: I3b9ac8ae5c05510d41377cae4dff1c69b40c2531
