mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Allow mknod(8) to be only invoked with a pathname as an argument.

In 99% of the cases people just want to recreate device nodes they
removed from /dev. There is no reason to pass the additional "c 0 0"
anymore.

Also slightly improve the manpage. Remove references to non-existent
device names and platforms.

Refine r198714, it's not as easy as just leaving the major number zero.

The majors file was removed long ago, 0 should be used instead.

Refer people looking to figure out what major to use for a device to
MAKEDEV and sys/conf/majors, not sys/conf/device.<arch>, which has
never existed in the history of FreeBSD (well, at least it isn't in
the repository).

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: sort SEE ALSO xrefs (sort -b -f +2 -3 +1 -2).

mdoc(7) police: Change -filled displays (which just happen
to be the same as -ragged in the current implementation) to
-ragged. With mdocNG, -filled displays produce the correct
output, formatted and justified to both margins.

mdoc(7) police: split punctuation characters + misc fixes.

Prepare for mdoc(7)NG.

mdoc(7) police: use the new features of the Nm macro.

Spelling fix.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Add chown(8)-like functionality. This will allow us to not use chown(8)
in MAKEDEV(8) -- removing the need of having /usr mounted.

$Id$ -> $FreeBSD$

Remove unused #include. Add usage().

I was porting something from sysV world and found our cross references
not quite as good as I would expect. So I'm introducing mknod to mkfifo,
and vice-versa.

Use the .At macro where appropriate.

Document that the major and minor numbers are parsed by strtoul().

Finally use strtoul() to convert the major an minor numbers, so
proper error-checking can be done, and octal and hexadecimal
numbers are allowed.

Correct some man page cross references and some file
locations.
