Fix quota(1) output.

- Fix calculation of 1024-byte sized blocks from disk blocks shown when -h
option isn't specified. It was broken with quota64 integration.
- In prthumanval(): limit the size of a buffer passed to humanize_number()
to a width of 5 bytes but allow a shorter length if requested. That's what
users expect.

Merger of the quota64 project into head.

This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options QUOTA # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

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.

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.

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).
