mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

Sync usage() and SYNOPSIS.

Follow the rules for the .Dd macro use: use unabbreviated month names.

Submitted by: ru

Use a separate synopsis line for -u as devinfo will ignore other
options when -u is specified. Xref device(9) and devclass(9).

o Don't print devices that aren't attached unless run with the newly
minted -v flag.
o Print devices that don't return a name as 'unknown' in -v mode.

# Yea! Now I wont think I have 10 different ISA network adapters in my
# laptop.

Typo fix: syste -> system

mdoc(7) police: Make this look like an average manpage.

o Uncapitalize .Nd macro arguments and remove punctuation
o Minor grammar fixes.
o Sort SEE ALSO references, and add iostat(8).
o Delete punctuation at end of AUTHORS' section only line

Add a man page for the devinfo command; I'd argue devinfo is the single
most useful new command added to FreeBSD 5.0, but maybe that's just
me :-).
