/* Idf module:
TOKEN idf_in_list(char *str, struct idf l[], sizeof l, TOKEN dflt);
looks up a keyword in a list of keywords l, represented as an
array of struct idf, and returns its translation as a token;
dflt is returned if the keyword is not found.
TOKEN idf_hashed(char *str);
returns a token unequal to SKIP or EOL, derived from the str
through hashing
It is assumed that SKIP will be ignored by the user of this module.
