   fix a few problems pointed out by clang static analyzer, from rajeev_v_pillai:

   - bozostrnsep() may return with "in = NULL", so check for it.
   - nul terminating in bozo_escape_rfc3986() can be simpler
   - don't use uniinit variables in check_remap()
   - don't use re-used freed data in check_virtual().  this one is tricky as
     the original code was:
        free(request->hr_file);
        request->hr_file = bozostrdup(httpd, request, s ? s : "/");
     however, bozostrdup() may reference request->hr_file.
