package: Add ZipOutputEntry to isolate deflating of streams. Preparation commit for deflating streams in parallel. We still use the same single XOutputStream (ByteChucker :-) for sequential writing but this can now be changed more easily. Change-Id: Idf26cc2187461660e31ac2e12c4708e761596fb2

package: Move most ZipOutputEntry's methods back to ZipOutputStream We want to use ZipOutputEntry only for deflating (and maybe rename it). ca13a9377e4a36436e4c82bb33648d0f3b6db6f5 was not a good idea because the data still needs to be written sequentially anyway. Otherwise it's hard to get offset positions of individual entries right. Since this commit rawCloseEntry needs to be called always; also when we use write&closeEntry because we don't call writeEXT in closeEntry anymore. Need to rename and add comments later.
