Refactor: libcib: Add compat note for XML_CIB_ATTR_REPLACE code
The code that set XML_CIB_ATTR_REPLACE was removed by commit c577e2a5 in
- We still have to maintain compatibility with external code that's
allowed to use this as public API. Hopefully nothing uses this
undocumented feature, but we'll support it for until an API break.
