//	** Return TRUE if the given SQL string ends in a semicolon.
//	**
//	** Special handling is require for CREATE TRIGGER statements.
//	** Whenever the CREATE TRIGGER keywords are seen, the statement
//	** must end with ";END;".
//	**
//	** This implementation uses a state machine with 8 states:
//	**
//	**   (0) INVALID   We have not yet seen a non-whitespace character.
//	**
//	**   (1) START     At the beginning or end of an SQL statement.  This routine
//	**                 returns 1 if it ends in the START state and 0 if it ends
//	**                 in any other state.
//	**
//	**   (2) NORMAL    We are in the middle of statement which ends with a single
//	**                 semicolon.
//	**
//	**   (3) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of
//	**                 a statement.
//	**
//	**   (4) CREATE    The keyword CREATE has been seen at the beginning of a
//	**                 statement, possibly preceded by EXPLAIN and/or followed by
//	**                 TEMP or TEMPORARY
//	**
//	**   (5) TRIGGER   We are in the middle of a trigger definition that must be
//	**                 ended by a semicolon, the keyword END, and another semicolon.
//	**
//	**   (6) SEMI      We've seen the first semicolon in the ";END;" that occurs at
//	**                 the end of a trigger definition.
//	**
//	**   (7) END       We've seen the ";END" of the ";END;" that occurs at the end
//	**                 of a trigger definition.
//	**
//	** Transitions between states above are determined by tokens extracted
//	** from the input.  The following tokens are significant:
//	**
//	**   (0) tkSEMI      A semicolon.
//	**   (1) tkWS        Whitespace.
//	**   (2) tkOTHER     Any other SQL token.
//	**   (3) tkEXPLAIN   The "explain" keyword.
//	**   (4) tkCREATE    The "create" keyword.
//	**   (5) tkTEMP      The "temp" or "temporary" keyword.
//	**   (6) tkTRIGGER   The "trigger" keyword.
//	**   (7) tkEND       The "end" keyword.
//	**
//	** Whitespace never causes a state transition and is always ignored.
//	** This means that a SQL string of all whitespace is invalid.
//	**
//	** If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
//	** to recognize the end of a trigger can be omitted.  All we have to do
//	** is look for a semicolon that is not part of an string or comment.
