Sync usage with man page.

Add 4 new flags:
-b (from FreeBSD) - set blocksize to blocks (512 bytes)
(overrides a contrary setting in BLOCKSIZE)
-H (from FreeBSD and Linux): -h using SI units (powers of 10). Ugh.

Add 4 new flags:
-b (from FreeBSD) - set blocksize to blocks (512 bytes)
(overrides a contrary setting in BLOCKSIZE)
-H (from FreeBSD and Linux): -h using SI units (powers of 10). Ugh.
-N suppress the header line (except with -P which requires it).
-f show only free space (or inodes) in a minimal format (implies -N)
(that is, with one file[system] specified, print 1 number only)
With -c, show only the total.
Intended to be useful for scripting (aka, I needed it.)

While here, improve the usage message (group options where they apply,
there is no reason, for example, that -g should be shown differently
to -k -m ..., and those options aren't at all useful with -G)

Update the man page to match.

Set totals.f_frsize to DEV_BSIZE instead of totals.f_bsize so that
addstat() uses an initialised value for total size calculations.
Fixes core dump for "df -c".

df: add grand total option

Add a grand total option, -c, similar to the du(1) -c option. Adapted from
the same option (-c) in FreeBSD df(1).

Print the wedge name with -W instead of mntfrom

-G cannot be specified alongside -i or -P.

Heads up by <leot>

Correct display of df(1) with the -i parameter

Now the "Mounted on" column should be aligned with /entries.

PR/50422: Robert Elz: df -G prints the wrong value for fragsize (+FIX)
For df -G, print the block and fragment size instead of the iosize
and the blocksize. If we need to print the iosize, it should be done
in a different field. Nevertheless printing the blocksize in the fragment
size field is just wrong.

use strspct.

Use the same column spacing for the -h output as with the normal output,
as the same header line format is used in both cases and it can't line
up correctly with both of them otherwise.

No need to print internal state once debug is done.

- static/__dead
- use strpct from libutil
- fix off by one in format

block numbers are measured in f_frsize units. Make -P option
use this instead of f_bsize. Also account for reserved blocks
like normal non-P output.
