Re: [PATCH v1] repository: move fetch_if_missing into struct repository

The global variable 'fetch_if_missing' controls whether a missing
object check should prompt a lazy fetch from a promisor remote.
In order to continue the libification effort, move it into
'struct repository' and initialize it to 1 by default to keep the
previous behavior.
