Re: [PATCH 0/3] Small fixups for `OBJECT_INFO` flags

Surprisingly though I found out that this breaks tests, which of course
puzzled me. As it turns out though, we were incorrectly using a couple
of these flags for `odb_has_object()`, and the changed definitions had
overlap with the existing meaning of other `HAS_OBJECT_*` flags. There
isn't really any bug here as far as I can see, but this is only really
by chance.

Great findings.

In any case, the first two commits fix calls to `odb_has_object()` that
used invalid flags. The last commit then removes the gaps and converts
the flags to use an enum instead.

Nice.
