Jonathan Kim 23a80ac554 [svn-r20103] Purpose:
Change to use HDxxx macros.

Description:
    Originally this started for fixing incorrect pointer usage. But that got
    fixed through coverity merge. So this is mainly changing to use HDxxx 
    macros and clean up some related code.
     
Tested:
 jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
