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.)
filesystem, instead of blocks and files together.
This results in fetching each FS-level quota entry twice and therefore
doing slightly more work, but (1) quota access isn't a critical path
and (2) after fetching the block values the file values will be hot in
the cache, so it won't add much total time.
Also move more of the FS-independent defintions from <quota.h> to
<sys/quota.h> so we can use them internally.
Step 4 of 5 for QUOTACTL_GET.
Note: this change requires a kernel version bump.
This is the user/application API and does not include the kernel
interface. Definitions shared with the kernel are found in
<sys/quota.h>.
Since I've been working on a local branch I have taken the liberty of
moving the latest-so-far version of <quota.h> to the front of the
patch queue. This loses (a small amount of) history but has the
advantage of avoiding unnecessary version bumps of libquota.so.
