[svn-r20929] Issue 4278 - When reading data fails, the error message should say which filter isn't registered. The fix is simple. Most of the effort is on the test. The file with filter enabled is created in gen_filter.c. The verification of the error message is in test_error.c. The output is compared against the standard output.
Tested on jam, koala, and heiwa.

Library
-------
+ - When a dataset had filters and reading data failed, the error message
+ didn't say which filter isn't registered. It's fixed now.
+ (SLU - 2011/6/3)
- The datatype handler created with H5Tencode/decode used to have the
reference count 0 (zero). I have fixed it. It is 1 (one) now.
