[PATCH 1/2] object-store: introduce OBJECT_INFO_NO_FETCH_IF_MISSING

[Christian Couder <christian.couder@gmail.com>]

The fetch_if_missing global variable should be replaced as much
as possible by passing a flag to oid_object_info_extended().

The existing OBJECT_INFO_FOR_PREFETCH unfortunately conflates
both a "no fetch if missing" meaning with OBJECT_INFO_QUICK
which is about retrying packed storage.

Let's disambiguate that by adding a new explicit
OBJECT_INFO_NO_FETCH_IF_MISSING flag.
