    ipsecconf: tidy parser.y
    
    - eliminate unused component "decimal" of struct kw_list
    
    - replace a lot of boilerplate with calls to new function "new_parser_kw"
    
    - use bool in place of int where appropriate
    
    - recast tests so they use boolean-valued expressions
    
    - use initializing declarations where this improves readability
    
    - reduce scopes of variables where possible
    
    - replace "strncmp(file, "-", sizeof("-")) == 0" with "streq(file, "-")"
      How does the first get invented?
    
    - improve formatting
