Several -mdoc parser improvements related to vertical spacing:

* So far, .Pp and .Lp were removed before paragraph type blocks.
* Now also remove .br before paragraph type blocks.
* Treat .Lp as a paragraph like .Pp, so remove .Pp, .Lp, .br before it.
* Do not treat .sp as a paragraph, don't remove anything before it.
* After .Sh, .Ss, .Pp, and .Lp, remove .Pp, .Lp, .sp, .br, and blank lines.
* After .sp and .br, remove .br.
