PatR f588a707bb groundwork for nethackrc name on command line ...

I've implemented 'nethack -nethackrc=filename' as an alternative to
'NETHACKOPTIONS='@filename' nethack' but at the moment it doesn't
work because the command line parsing comes after the run-time config
file has already been processed.  But this part should work, or maybe
have problems spotted and fixed if it doesn't.  The RC file part of
initoptions_finish() has been rewritten so that it won't need extra
replication of
|  set_error_handling()
|  process_file()
|  reset_error_handling()
|  if (NETHACKOPTIONS) {
|    set_error_handling()
|    process_options()
|    reset_error_handling()
|  }
I've tried to test all the combinations mentioned in the comment but
am not sure that I covered everything, particulary for repeating
earlier tests after making incremental changes.
