We now write to the parcel using deltas. For common situations, it only takes 4 bytes to write a delta (new command, time delta, significant state changes, flags indicating additional state that follows). Increasing the buffer size to 128K, this give us 32,768 samples if they all fit in the smallest delta. A device that is doing something every minute (like acquiring a wake lock or doing a wifi scan) for our max target battery life of 30 days would generate 43,200 samples. Also some turning to the maximum time between samples at which we decide to completely collapse two samples. Change-Id: I074a698d27ccf9389f9585abfc983af2f5ba7a54
