This adds a new quotactl, Q_XGETQUOTA2.

Q_XGETQUOTA2 is exactly like Q_XGETQUOTA, except that it will
return quota information for the id equal to or greater than
the id requested.  In other words, if the specified id has
no quota, the command will return quota information for the
next higher id which does have a quota set.  If no higher id
has an active quota, -ESRCH is returned.

Please add a flags argument to Q_XGETQUOTA2, and then make the
new behavior the first flag.  Keep Q_XGETQUOTA behavior for the
flag-less case.  That way we get future etensibility for free.
