[svn-r5904]

Purpose:
    Added 'ID to name' support
Description:

    There is a new API function H5Iget_name
    Most of the changes are on H5G.c , regarding the symbol table entry struct H5G_entry_t
    which has 2 new fields 'name' and 'old_name'

    A new private function was introduced H5G_ent_copy, that does a deep copy
    between 2 symbol table entries

    The test file is getname.c


Platforms tested:
    windows 2000, Linux, Solaris
