The last big commit: let usr.sbin/ use WARNS=6 by default.

- Make pstat(8) WARNS=6 safe.
- While here, eliminate the check for len > 0 in ttymode_sysctl
as the code is able to handle this case well.

Reviewed by: ed (initial version)

Use a designator for initializing only one member of the nlist
structs, making pstat WARNS=3 clean on i386, sparc64 and amd64.

Bump WARNS level to 3.

- Add a -h flag to pstat to print swap sizes in "human readable"
format, with humanize_number(3).

- Move the common parts of the code that prints the sizes for a single
swap device and the total to a single function to avoid repeating
the humanize_number() stuff all over the place.

- Change the type of CONVERT() from intmax_t to int64_t, since this
makes calling humanize_number() easier but cast the values to
intmax_t before printing them, to make use of the %jd format that
printf() supports.

- Document the new -h flag in the manpage and bump its date.

style.Makefile(5)

Remove the code that was disabled in a recent commit; it is of very limited
use and has been broken in -CURRENT for a long time.
Clean up unneeded entries in the nlist array.
Implement kvm-backed ttymode (which we never had before). Incomplete as we
do not (yet?) print the correct device, sid or pgid.

Un-kmemize. Portions of the tty mode code have been temporarily disabled;
everything else, including dead kernel support, works just like before.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file
systems were repo-copied from sys/miscfs to sys/fs.

- Renamed the following file systems and their modules:
fdesc -> fdescfs, portal -> portalfs, union -> unionfs.

- Renamed corresponding kernel options:
FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.

- Install header files for the above file systems.

- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland
Makefiles.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Previous commit to remove -I/sys broke 'make world', miscfs/union/*.h is
not (yet?) installed in /usr/include.

Remove -I/sys

Make pstat act like swapinfo if so invoked.

Get rid of update. Make man page installation work with our scheme
(and rename a few in the process).
