Update moused(8) and mouse(4) to reflect the cuaa->cuad name change.

Submitted by: Steve Kargl <sgk@troutmask.apl.washington.edu>

Mechanically kill hard sentence breaks and double whitespaces.

mdoc(7) police: Use the new .In macro for #include statements.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

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

Initiate deorbit burn sequence for <machine/mouse.h>.

Replace all in-tree uses with <sys/mouse.h> which repo-copied a few
moments ago from src/sys/i386/include/mouse.h by peter.
This is also the appropriate fix for exo-tree sources.

Put warnings in <machine/mouse.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/mouse.h> files will be removed.

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.

Mention USB mouse support.

* remove i386 specific mark
* some style and syntax fixes
