Fix various, mostly minor errors in man pages like:

- Abbreviated month name in .Dd
- position of HISTORY section
- alphabetical ordering within SEE ALSO section
- adding .Ed before .Sh DESCRIPTION
- remove trailing whitespaces
- Line break after a sentence stop
- Use BSD OS macros instead of hardcoded strings

No .Dd bumps as there was no actual content change made
in any of these pages.
