Pull up following revision(s) (requested by bouyer in ticket #580):
	tests/fs/ffs/h_quota2_tests.c: revision 1.4
	tests/fs/ffs/t_miscquota.sh: revision 1.7
	sys/ufs/ufs/ufs_quota2.c: revision 1.35
Fix quota2 list corruption issue when defaultquotas are 0 (deny any file
and block allocation).
When quota2_check() is called with an uid not yet in the list,
getinoquota2() will call quota2_q2ealloc() to allocate a new entry for this
uid. quota2_q2ealloc() will remove an entry from the free list and
put it at the head of the corresponding hash list, and flush the block
containing the header if it's not the one also containing the allocated entry.
quota2_q2ealloc() then return the alocated entry and corresponding block
to caller (getinoquota2() here), which returns it to quota2_check().
quota2_check() then checks if the allocation can succeed, and returns and
error if not and calls brelse() on the buffer (because from his POW no
change was made to the entry), effectively discarding changes
to the entry that may have been made by quota2_q2ealloc().
Fix by always bwrite()ing the entry in quota2_q2ealloc(), and re-reading
the entry in caller.
Add test cases for the bug fixed in sys/ufs/ufs/ufs_quota2.c 1.35:
when a on-disk block/inode allocation triggers allocating a new
quota entry, the new quota entry is not in the quota2 header block,
and the allocation will later be denied, the changes to the quota block would
not be flushed to disk, leading to list corruption (detected by fsck).

Per the FS-independent schema, get one quotaval at a time from the
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.

Add a new libquota library, which contains some blocks to build and/or
parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).
Discussed on tech-kern@ and tech-net@ (long thread, but not much about
libquota itself ...)

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Implement clear command (quota2 only), which either free the specified
quota2 entry (if both disk and inode usage are 0) or revert its limits to
the default quota entry.

Catch up with Q2V -> QL renaming
Enforce limits for quota2.
pass quota type (*QUOTA) and limit type (QL_*) to
KAUTH_REQ_SYSTEM_FS_QUOTA_NOLIMIT, to make it possible to skip
limit checks for some quota type only if a listener wants to.

Introduce quota2_ufs_rwq2v() and quota2_ufs_rwq2e() functions, which
byteswap a quota2_val or quota2_entry if needed.
Use this to get quota2_entry in host order before calling q2etoprop().

quota2_walk_list() will byteswap the offset if needed to leave
it in FS byte order in callers.

Snapshot of work in progress on a modernised disk quota system:
- new quotactl syscall (versionned for backward compat), which takes
  as parameter a path to a mount point, and a prop_dictionary
  (in plistref format) describing commands and arguments.
  For each command, status and data are returned as a prop_dictionary.
  quota commands features will be added to take advantage of this,
  exporting quota data or getting quota commands as plists.

- new on disk-format storage (all 64bit wide), integrated to metadata for
  ffs (and playing nicely with wapbl).
  Quotas are enabled on a ffs filesystem via superblock flags.
  tunefs(8) can enable or disable quotas.
  On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid
  block and inode usages, and will check and update quotas in Pass 6.
  quota usage and limits are stored in unliked files (one for users,
  one for groups)l fsck_ffs(8) will create the files if needed, or
  free them if needed. This means that after enabling or disabling
  quotas on a filesystem; a fsck_ffs(8) run is required.
  quotacheck(8) is not needed any more, on a unclean shutdown
  fsck or journal replay will take care of fixing quotas.
  newfs(8) can create a ready-to-mount quota-enabled filesystem
  (superblock flags are set and quota inodes are created).
  Other new features or semantic changes:
  - default quota datas, applied to users or groups which don't already
    have a quota entry
  - per-user/group grace time (instead of a filesystem global one)
  - 0 really means "nothing allowed at all", not "no limit".
    If you want "no limit", set the limit to UQUAD_MAX (tools will
    understand "unlimited" and "-")

  A quota file is structured as follow:
  it starts with a header, containing a few per-filesystem values,
  and the default quota limits.
  Quota entries are linked together as a simple list, each entry has a
  pointer (as an offset withing the file) to the next.
  The header has a pointer to a list of free quota entries, and
  a hash table of in-use entries. The size of the hash table depends
  on the filesystem block size (header+hash table should fit in the
  first block). The file is not sparse and is a multiple of
  filesystem block size (when the free quota entry list is empty a new
  filesystem block is allocated). quota entries to not cross
  filesystem block boundaries.

  In memory, the kernel keeps a cache of recently used quota entries
  as a reference to the block number, and offset withing the block.
  The quota entry itself is keept in the buf cache.

fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with
related atf tests :)
The kernel can update disk usage and report it via quotactl(2).

Todo: enforce quotas limits (limits are not checked by kernel yet)
      update repquota, edquota and rpc.rquotad to the new world
      implement compat_50_quotactl ioctl.
      update quotactl(2) man page

fsck_ffs required fixes so that allocating new blocks or inodes will
properly update the superblock and cg sumaries. This was not an issue up
to now because superblock and cg sumaries check happened last, but now
allocations or frees can happen in pass 6.
