6.2.0.32

Version 6.2.0.32

Note: This is a pre-release version, future versions of VDO may not support
      VDO devices created with this version.
- Add a library, libuser.a, to provide easy access to VDO user space code
  for other projects.
- Fixed a bug in vdo script when /dev/disk/by-id does not exist.
- Fixed an internationalization bug in the vdo script's --indexMemory
  option.
- Changed vdo script to not accept --vdoSlabSize=0 as a way of specifying
  the default since it was confusing. The default can be obtained by merely
  omitting the parameter entirely.
