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

Hi,

I was kind of curious why there were gaps in the `OBJECT_INFO_*` flags, but eventually found out that these gaps are of historic nature: there used to be more flags, but their respective values got removed at one point in time. So naturally, I wanted to clean this up a bit so that the next reader wouldn't have the same question.

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.

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.

Thanks!

Patrick
