Gives about a 2-3x reduced data file size. Should help reduce the time
we spent transferring trace files on Android.

This feature is implemented as a parameter to the capture/replay tool.
This keeps backwards compatiblity if we ever need to integrate a cpp
replay into an environment that doesn't have access to zlib for
decompression.

We'll need to update the traces to take advantage of the compression.
