Merge release 1.11.3, almost all code by kristaps@:

* Unicode output support (no Unicode input yet, though).
* Refactoring: completely handle predefined strings in roff.c.
- New function mandoc_escape() replaces a2roffdeco() and mandoc_special().
- Start using mandoc_getarg() in mdoc_argv.c.
- Clean up parsing of delimiters in mdoc(7).
* And many minor fixes and lots of cleanup.
