From: Paolo Bonzini <pbonzini@xxxxxxxxxx>
Separate the mechanical changes out of the next patch. The functions
are changed to take a pointer to enum, because struct conf_info is not
going to be public.
Set the default values explicitly in default_conf_info, since they are
not anymore close to default_conf_info and it's not obvious which
constant has value 0. With the next patches, in fact, the values will
not be zero anymore!
