From: Paolo Bonzini <pbonzini@redhat.com>
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!

From: Paolo Bonzini <pbonzini@redhat.com>
Allow using non-default values for trailers without having to set
them up in .gitconfig first. For example, if you have the following
configuration
trailer.signed-off-by.where = end
you may use "--where before" when a patch author forgets his
Signed-off-by and provides it in a separate email. Likewise for
--if-exists and --if-missing
Reverting to the behavior specified by .gitconfig is done with
--no-where, --no-if-exists and --no-if-missing.
