[svn-r9890] Purpose: Clean up tests

Description:
    + C tests' macro VERIFY casts values to 'long' for all cases.  Since
      there are no operator<< for 'long long' or int64 in VS C++ ostream,
      I casted the hsize_t/hssize_t values passed to verify_val to 'long'
      as well.  If problems arise later, this may have to be specificly
      handled with an overload - th5s.cpp
    + Added the use of InvalidActionException for when an action
      should cause an exception but didn't - th5s.cpp and tfile.cpp
    + Small changes to improve failure reports

Platforms tested:
    SunOS 5.7 (arabica)
    Linux 2.4 (eirene)
