Be consistent about whether idtype and objtype codes are signed or unsigned. They are signed. (While unsigned might have been a better choice, it doesn't really matter and the majority of preexisting uses were signed. And consistency is good.)

/* $NetBSD: quotapvt.h,v 1.14 2012/02/01 05:46:46 dholland Exp $ */
Add initial versions of quota_open(), quota_close(), quota_get(), calling proplib code mostly taken from getufsquota(). Correct the proplib refcount handling in the code from getufsquota(), where it was (as far as I can tell) wrong. Avoid doing illegal and unsafe casts from (struct quotaval *) to (uint64_t *).

Improve how quota_open() works and generally improve function dispatching. Allow access to the quota files via the oldfiles code if quotaon hasn't run yet. Change the latter so it calls getfsent() up front (and only once) to make it easier to avoid whacking caller state.

#define QUOTA_MODE_NFS 1
