[svn-r25582] Dynamic VOL plugin loading:
- add support for searching for plugins by name in the H5PL interface
- add support for searching for VOL plugins and returning the plugin structure
- implement H5VLregister_by_name
- add tests similar to the filter plugin tests
- still needs some refactoring and better test framework and cmake support.
