[svn-r8801] Purpose:
Code optimization Description: Set up datatype ID for dataset's datatype on disk. This allows us to avoid repeatedly copying the datatype when an ID is needed. Also, clean up a few warnings in various other places. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
