Add <quota.h> with the new libquota API.
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.
