[Clam-devel] Disable state is no more

[David García Garzón]

One commit i did yesterday, i forgot to report to the list, is the removal of 
the Disabled state. It was marked as deprecated since some months, now i 
removed it from the code (commit 9729). 

I did several transversal changes on CLAM processings.

- In the Do returned true before doing anything. I removed it.
- Also in the Do some ASSERT preconditions on not being on Unconfigured or 
Ready, that i changed just to assert being Running.

Hope not having broken anything.

David.
