[svn-r9354] Purpose:
Bug fix & code cleanup
Description:
More dataset cleanups to get to a point where we can fix the chunked I/O
bug.
Also fix a couple of errors in the recent file object resurrection changes
which should hopefully address the recent daily test failres (H5T.c)
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
