This cl supports the parsing and extraction of the zip entry who has a large size than UINT32_MAX. Also add a few checks in the entry writers to make sure callers have enough space for extraction. As many users of the library assume the entry size to be 32 bits long, we keep the 32 bit ZipEntry. We also keep the functions that expect the 32 bit ZipEntry in the public header file. These 32 bit wrappers could be removed later once all users recognize the 64 bit ZipEntry. Bug: 150900468 Test: unit tests pass Change-Id: Ia6760638ccf51e97dbef6bd55dff352f1e7ce816
