parsers: fix buffer overflow by invalid parent revision read from revlog If revlog file is corrupted, it can have parent pointing to invalid revision. So we should validate it before updating nothead[], phases[], seen[], etc. Otherwise it would cause segfault at best. We could use "rev" instead of "maxrev" as upper bound, but I think the explicit "maxrev" can clarify that we just want to avoid possible buffer overflow vulnerability.
