Disable SHOPT_KIA (ksh -R) by default

Browse source 
SHOPT_KIA enables the -R option that generates a cross-reference
database from a script. However, no tool to analyse this database
is shipped or seems to be available anywhere (in spite of multiple
people looking for one), and the format is very opaque. No usage
examples are known or findable on the internet. This seems like it
should not be compiled in by default, although we'll keep the code
in case some way to use it is found.

src/cmd/ksh93/SHOPT.sh:
- Disable SHOPT_KIA by default by removing the default 1 value.

src/cmd/ksh93/sh/args.c, src/cmd/ksh93/sh/parse.c:
- Fix a couple of preprocessor logic bugs that made it impossible
  to compile ksh without SHOPT_KIA.

src/cmd/ksh93/data/builtins.c:
- Fix typo in -R doc in ksh --man (in case SHOPT_KIA is enabled).

src/cmd/ksh93/sh.1:
- Since sh.1 is not generated dynamically, remove the -R doc.
