Create and register one config item.

Parameters

errBuffer for error messages
Return values
ptrNew HashElem representing the config item

Similar to cs_register_variable() but copies the ConfigDef first. Allowing the caller to free it and its parts afterwards.

This function does not know anything about how the internal representation of the type must be handled. Thus, the fields 'initial', 'data', 'var' must be copyable. If they need allocation, then the caller must set them after the variable is created, e.g. with cs_he_initial_set(), cs_he_native_set.
