[svn-r23519] I used H5Gcreate instead of H5Gcreate2 in plugin.c. I corrected it and added some real operation in the dummy filter library dynlib3.c.

Tested on jam and koala.

  * Function:	H5Z_filter_dynlib3

- * Purpose:	A dynlib3 filter method that adds on and subtract from
- *              the original value with another value.  It will be built 
- *              as a shared library.  plugin.c test will load and use 
- *              this filter library.    
+ * Purpose:	A dynlib3 filter method that is used to test groups.  It 
+ *              appends the suffix ".h5group" to each group name during 
+ *              write and takes it out during read.
  *
  * Return:	Success:	Data chunk size
  *
  *		Failure:	0
