Integrate kristaps@' end-of-sentence (EOS) framework

which is simpler and more powerful than mine, and remove mine.

* man(7) now has EOS handling, too
* put EOS detection into its own function in libmandoc
* use node and termp flags to communicate the EOS condition
* no more EOS pseudo-macro
* no more non-printable EOS marker character on the formatter level

This slightly breaks EOS detection after trailing punctuation
in mdoc(7) macros, but that will be restored soon.
