[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
