1. Fixing page pruning / compaction crash …

   Issue: the heap AM has a function which automatically compacts pages
   when certain conditions are met. When this happens, it moves the
   tuples around within the page. As encryption uses the offset of tuples
   for decrypting them, this results in garbage data and possible crashes.
   
   Fix: this commit copies the two compaction functions from the server code,
   and modifies them to re-encrypt data when moved. This is not optimized at
   all, if needed, we can improve this by a lot.
   
   Also, for now only one execution path is handled from the two, as that's
   the only one hit by sysbench. We'll have to figure out a testcase for
   the other and fix that too, for now, it only contains an assert(0).
