[svn-r9351]

Purpose:  enhanced feature

Description:  enable  size adjustment for compound datatype.  The size
can be increased and decreased(as long as the members are not cut).

Solution:  mainly check if any member is being cut when decreasing the
size.  Others are simply taking out the assertion against 0 size.

Platforms tested:  h5committest and fuss.

Misc. update:  RELEASE.txt
