[svn-r14930] Maintenance: Fixed more bugs/typos and enabled tests that were failing previously on linew.
             Currently only one test (dense attributes) is failing. It looks like C library problem and we
             have a similar bug report in Bugzilla: when dense storage is used, attributes are not written
             to the file; somehow similar C test doesn't expose the problem while Fortran test does.

Platforms tested: linew, kagiso with g95 and PGI
