Merge version 1.11.1:

Again lots of cleanup and maintenance work by kristaps@.
- simplify error reporting: less function pointers, more mandoc_[v]msg
- main: split document parsing out of main.c into read.c
- roff, mdoc, man: improved recognition of control characters
- roff: better handling of if/else stack overflows
- roff: add some predefined strings for backward compatibility
- mdoc, man: empty sections are not errors
- mdoc: move delimiter handling to libmdoc
- some header restructuring and some minor features and fixes
This merge causes two minor regressions
that i will fix in separate commits right afterwards.
