Optimizations to reduce verity verification time
Test: with CPU locked to low freq, verification time of a 400 MB apk is
reduced from about 2528 ms to 1942 ms, vs 915 ms of the old
algorithm. Writing directly into ByteBuffer's backing array saves
around 100 ms but it does not work for DirectByteBuffer, thus I
didn't implement this optimization.
