hdf5_ep

[svn-r11013] Purpose:
Bug fix

Description:
Fixed bugs that caused tests to be unable to find testhdf5.sh during
daily tests, and another that broke sol and shanti.

Solution:
When tests are run, their path is ./$testname .
When scripts are run, their path has no leading "./".  Fixed.
Sol and shanti don't recognize the -e option for test, but they do know
-f.  Fixed.
Also modified release notes.

Platforms tested:
mir, shanti, heping
