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.

returns a token unequal to SKIP or EOL, derived from the str

It is assumed that SKIP will be ignored by the user of this module.
