/*
 * ntp.conf syntax is slightly irregular in that some tokens such as
 * hostnames do not require quoting even if they might otherwise be
 * recognized as T_ terminal tokens.  This hand-crafted lexical scanner
 * uses a "followed by" value associated with each keyword to indicate
 * normal scanning of the next token, forced scanning of the next token
 * alone as a T_String, or forced scanning of all tokens to the end of
 * the command as T_String.
 * In the past the identifiers for this functionality ended in _ARG:
 *
 * NO_ARG	->	FOLLBY_TOKEN
 * SINGLE_ARG	->	FOLLBY_STRING
 * MULTIPLE_ARG	->	FOLLBY_STRINGS_TO_EOC
 *
 * Note that some tokens use FOLLBY_TOKEN even though they sometimes
 * are followed by strings.  FOLLBY_STRING is used only when needed to
 * avoid the keyword scanner matching a token where a string is needed.
 *
 * FOLLBY_NON_ACCEPT is an overloading of this field to distinguish
 * non-accepting states (where the state number does not match a T_
 * value).

/* STRUCTURES

/* 
 * Define a structure to hold the FSA for the keywords.
 * The structure is actually a trie.
 *
 * To save space, a single u_int32 encodes four fields, and a fifth
 * (the token completed for terminal states) is implied by the index of
 * the rule within the scan state array, taking advantage of the fact
 * there are more scan states than the highest T_ token number.
 *
 * The lowest 8 bits hold the character the state matches on.
 * Bits 8 and 9 hold the followedby value (0 - 3).  For non-accepting
 *   states (which do not match a completed token) the followedby
 *   value 3 (FOLLBY_NONACCEPTING) denotes that fact.  For accepting
 *   states, values 0 - 2 control whether the scanner forces the
 *   following token(s) to strings.
 * Bits 10 through 20 hold the next state to check not matching
 * this state's character.
 * Bits 21 through 31 hold the next state to check matching the char.
