[svn-r5023] Purpose:

	Bug Fix
Description:
	There was a problem with having a lot of groups nested together. We
	could only handle 1024 characters at most, but, in a parallel program
	especially, it could occur that there were lots and lots of groups
	and would be more than 1024.
Solution:
	I made the "objname" part of the obj_t structure a pointer instead of
	a fixed size. Added code to allocate/deallocate the memory we need
	for it. Had to fix how the "prefix" was being handled in the h5dump
	program. It was also set to only 1024 characters in length. I made it
	dynamic.

	Added a test case...Go me!
Platforms tested:
	Linux, Solaris
