[svn-r10067] Purpose:

feature

Description:
h5repack support for scaleoffset compression

Checking in early to help debug the filter.

Solution:
Added messages and command line to handle new scale offset filter.

Note:  TESTS ARE DISABLED FOR NOW.  The filter is not
complete, repack tests may fail due to know problems.

PLEASE DO NOT MESS WITH THE SCALEOFFSET TESTS AT THIS TIME.

They will be enabled when the filter is ready.

Platforms tested:
verbena,copper,shanti

Misc. update:
