Description:
    Put back overloaded functions for backward compatibility:
    - were replaced by better prototyped versions, such as Attribute::getName.
    - were modified to add const to constant arguments.
    Added notes for future removal in documentation.
Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
