New Issue: I/O Module: Deprecate ''file.getchunk''

This issue concerns the method file.getchunk:

proc file.getchunk(start:int(64) = 0,
                   end:int(64) = max(int(64))) : (int(64),int(64)) throws

This method was developed a long time ago as part of some distributed filesystem work, but has been somewhat abandoned due to various priorities.

We should deprecate this method. There is not currently an appropriate replacement, but this method appears to have no testing and is probably in a questionable state, so deprecation seems most fitting.
