BUG: 329 (Replacing memory allocation functions with mem-type functions)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=329

* support O_TRUNC flag in open (call comes to FS as 'truncate'
  or 'ftruncate' fop)
* option to provide 'eliminate-pattern' so those files matching
  won't be kept in trash. Eg:
      option eliminate-pattern *.out|*~
* option to give 'maximum' file size to keep in trash, ie, when a
  20GB file is deleted, it won't be kept in trash if max file size
  given is 1GB. Eg:
      option max-trashable-file-size 1GB

These particular features are developped as a part of college project
by following team:

BUG: 142 (enhance features/trash  translator so it can work on client side too..)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=142

This way, users will be aware which are in 'beta' stage, and we can keep on
adding new translators (if any) seemlessly to stable codebase and once tested
can move them to proper places.

To use these translators, everyone will have to prefix 'testing/' to existing
type of translator (in volumefile)
