Sort sections.

Add a HARDWARE section which lists supported devices.

MFC after: 3 days

Mechanically kill hard sentence breaks and double whitespaces.

Add two PC-98 devices, from the hardware notes, which was missed in
the last commit.

MFC after: 1 week

Sync the sym(4) manual page with the hardware notes, and change the
list of supported controllers into a list.

Note that the 53C875A has not been included in the list of supported
devices, since this controller does not seem to be supported by the
version of the sym(4) driver currently in FreeBSD.

53C875A omission reviewed by: silence from -scsi and groudier

Document the KZPCA-AA.

Consistently use 'queueing' instead of 'queuing'. Both spellings are
correct, but the former seems to be preferred. This makes all of the
section-4 manual pages consistent in this respect.

mdoc(7) police: s/BSD/.Bx/ where appropriate.

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

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

Remove the MD part from the document title.

Miscellaneous fixes.

Document driver support for:
- Early NCR53C810/815/825 chips.
- Newer chip architectural improvements (Hardware phase
mismatch and LOAD/STORE instructions).

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.

Third round of config related changes to the manpages.

device blah0 -> device blah for PCI devices and busses.

`sym' driver man page addition.
