[svn-r8742] Purpose: New feature and bug fix.

Description:  1. A new API function H5Fget_filesize was added to return the actual size
of an opened file.  2. In H5Gpublic.h, object types are defined as integers in v1.4
instead of H5G_obj_t in v1.6.  In titerate.c, H5G_obj_t couldn't be recognized if compatibility
with v1.4 is enabled.

Solution: 1.  Call H5FDget_eof to return file size in H5Fget_filesize.  2. When compatibility with
v1.4 is enabled, define variable as integer instead of H5G_obj_t.

Platforms tested:  h5committest.

Misc. update:  RELEASE.txt
