[svn-r24555] - Many updates to fix assertion checking ... look for values < 0 as errors.
- Many updates to let things fail without stopping the application - failure return codes for update operations are expected 
  when transactions are aborted.
- Rather than use assert to check return codes, added STATUS macro & some in-code if ()'s to print OK or FAILED rather than
  abort
- Reformatted output of print_container_contents to be easier to read & more compact.
- Other misc changes.

- THIS VERSION STILL HAS ISSUES - get -1 returned from delete operations that are successful.  Look for DEBUG in fprintfs
  to see where these are happening.    Have reported to Mohamad & once lower-layers are fixed these DEBUG statements should
  be removed.
