capgen host model DDT problem

[gold2718]

Description

The host CCPP metadata table type should be able to accept DDT items.
However, the error variables are somewhat special and they are not handled correctly when inside a DDT.

Steps to Reproduce

1. Create a DDT
2. Add the ccpp_error_message and/or ccpp_error_code variables to the DDT
3. Add a variable of this DDT type to the host table type = host metadata table
4. Run capgen

@gold2718 I ran into a possibly related issue wrt to the ccpp error handling variables.
When porting the framework ccpp_t type to the SCM, I had to remove the ccpp error handling variables from this DDT and provide them to the host as flat variables.
Also, as the caps are written now, it is mandatory for you to supply ccpp error handling variables (If you don't the caps will try to initialize them, but they aren't declared).

@dustinswales, this is exactly the issue. I am working on a fix.
