Subject: [svn-r8739] Purpose:  New feature and Bug fix

Description:  1.  Added H5Fget_filesize and test(in file_handle.c) which returns
the actual file size of an opened file.  Also added to C++ API and test.
2.  The error tests were messed up in test/Makefile.in.

Solution:  1.  Call H5FDget_eof to return file size.  2. Corrected.

Platforms tested:  h5committest

Misc. update:  RELEASE.txt
