[PATCH RFC 2/5] fetch-object-info: add enum for fetch_object_info() statuses

[Pablo Sabater <pabloosabaterr@gmail.com>]

fetch_object_info() dies when the server does not advertise the
object-info capability. That is fine for git cat-file
remote-object-info command, which cannot work without it. However
a subsequent commit needs fetch_object_info() to not die, to be
able to fallback.

Add "enum fetch_object_info_status" so that fetch_object_info() can
report this case to its callers. It is used in a subsequent commit.
