[svn-r18174] Bug ID 1753: added macro version of GetTestVerbosity.

The previous implementation did not work for WIndows.
Moved the macro definition of HDGetTestVerbosity from testhdf5.h
to h5test.h.

Removed as much as possible macro definitions that use HDGetTestVerbosity
directly.

Tested: Jam (serial and parallel).  Did not run h5committest since this
is a trival change that is portable.
