Merge branch 'cw/prelim-cleanup'

Shuffle some bits across headers and sources to prepare for
libification effort.

* cw/prelim-cleanup:
  parse: separate out parsing functions from config.h
  config: correct bad boolean env value error message
  wrapper: reduce scope of remove_or_warn()
  hex-ll: separate out non-hash-algo functions
