Cleanup suggested by gcc-4.8.1, following hints by Christos Zoulas:

- avoid bad qualifier casting in roff.c, roff_parsetext()
  by changing the mandoc_escape arguments to "const char const **"
- avoid bad qualifier casting in mandocdb.c, index_merge()
- do not complain about unused variables in test-*.c
- garbage collect a few unused variables elsewhere
