aad5531e71 This exposes ZFS user and group quotas via the normal
quatactl(2) mechanism.  (Read-only at this point, however.)
In particular, this is to allow rpc.rquotad query quotas
for NFS mounts, allowing users to see their quotas on the
hosts using the datasets.

The changes specifically:

* Add new RPC entry points for querying quotas.
* Changes the library routines to allow non-UFS quotas.
* Changes rquotad to check for quotas on mounted filesystems,
rather than being limited to entries in /etc/fstab
* Lastly, adds a VFS entry-point for ZFS to query quotas.

Note that this makes one unavoidable behavioural change: if quotas
are enabled, then they can be queried, as opposed to the current
method of checking for quotas being specified in fstab.  (With
ZFS, if there are user or group quotas, they're used, always.)

404d2fee56 quota(1): Fix calculation overflow and underflow
For very large quotas, do the multiplication as a 64 bit value to avoid
overflow.

For very small block sizes (smaller than DEV_BSIZE), multiple first
before dividing by block size to avoid underflow.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

54404cfb13 In preparation for raising NGROUPS and NGROUPS_MAX, change base
system callers of getgroups(), getgrouplist(), and setgroups() to
allocate buffers dynamically.  Specifically, allocate a buffer of size
sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow).

This (or similar gymnastics) is required for the code to actually follow
the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime
and where getgroups may return {NGROUPS_MAX}+1 results on systems like
FreeBSD which include the primary group.

In id(1), don't pointlessly add the primary group to the list of all
groups, it is always the first result from getgroups().  In principle
the old code was more portable, but this was only done in one of the two
places where getgroups() was called to the overall effect was pointless.

Document the actual POSIX requirements in the getgroups(2) and
setgroups(2) manpages.  We do not yet support a dynamic NGROUPS, but we
may in the future.

f5374712ce If a user is over both the soft block limit and soft i-node
limit, quota will report one of the grace times incorrectly.
This is due to it storing the result in a static buffer, and the
routine being called like:
	printf("....", ..., timeprnt(btime), timeprnt(itime), ...)

The problem becomes very obvious if you change one of the default
grace periods to be much larger than the other one.

Changed timeprnt to dynamically allocate the string to be displayed.

fbb42904c4 If two files systems, /a and /b are marked as having quotas enabled
in fstab and they are normally mounted as /a/b, if /b is not mounted,
the various quota utilities will incorrectly operate with the quotas on
/a (silently) when operations are attemted on /b.

Sync up all the hasquota() routines between all the different
quota utilities and change it to detect if the file system we are
attempting to perform quota operations on is not currently mounted
and warn the user accordingly.

aee1b42ab6 Now that the kernel access control for quotactl(2) appears to work
properly, clean up quota(1).  quota(1) has the ability to query
quotas either directly from the kernel, or if that fails, by reading
the quota.user or quota.group files specified for the file system
in /etc/fstab.  The setuid bit existed solely (apparently) to let
non-operator users query their quotas and consumption when quotas
weren't enabled for the file system.

o Remove the setuid bit from quota(1).

o Remove the logic used by quota(1) when running setuid to prevent
  users from querying the quotas of other users or groups.  Note
  that this papered over previously broken kernel access control;
  if you queried directly using the system call, you could access
  some of the data "restricted" by quota(1).

In the new world order, the ability to inspect the (live) quotas of
other uids and gids via the kernel is controlled by the privilege
requirement sysctl.  The ability to query via the file is controlled
by the file permissions on the quota database backing files
(root:operator, group readable by default).
