Log message:
    Re-implement psql's input scanning to use a flex-generated lexer, as per
    recent discussion.  The lexer is used for both SQL command text and
    backslash commands.  The purpose of this change is to make it easier to
    track the behavior of the backend's SQL lexer --- essentially identical
    flex rules are now used by psql.  Also, this cleans up a lot of very
    squirrelly code in mainloop.c and command.c.  The flex code is somewhat
    bulkier than the removed code, but should be lots easier to maintain.
