hdf5_ep

[svn-r14597] Purpose: Backport Windows cleanup checkins from trunk

Description:
Make the Windows copy_hdf.bat a little cleaner/safer, and produce useful output in installhdf5lib.bat

Previously, all of our build output would simply go to stdout/stderr for command-line builds.  We can pipe this into a log file as a whole, but the complete logfile becomes very large very quickly.  Instead, we give the user an option to place build results and test results into separate logs (or even the same).  This will help keeping track of results in our automated testing.

Tested:
VS2005 on WinXP
