Mdoc Janitor:

* Use 'manual' instead of 'man' for consistency.

Mdoc Janitor:

* Fix hard sentence breaks.

* NOTE: devstat(9) requires more mdoc(7) work.

device_is_alive already was documented in device_get_state, so remove the
separate man page. Document new device_is_attached there and remove that
new man page too.

Connect device_get_name to build, and install a link for
device_get_nameunit.

strangely nobody noticed this yet...

mdoc(7) police: Deal with self-xrefs.

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...
