[svn-r8644] Purpose: h5dump new features

Description:

added the code for print strings with new line and display the path of references (new source files h5tools_ref.c and .h )
added a test suite in testh5dump.sh.in for
( note : to create testh5dump.sh , one must redo ./configure; this detects the availability of filters
and generates  testh5dump.sh accordingly)
1) storage layout
2) fill value
3) print reference with path
4) print strings with new lines
5) filters

Solution:

Platforms tested:
linux
solaris
AIX
