    Fix a couple use-after-free bugs in RIP

    This likely is the cause of bug 140.

    The first one, the LCF flag is copied out of the cterm struct
    after cterm_end() is called (which frees the struct). Copy moved
    to before cterm_end().

    The second one is trickier... it's executing the commands in a mouse
    button, and one of the commands is to delete all the mouse button
    commands. This ends up free()ing the string that's currently being
    parsed while it's being parsed. We now use a strdup() of the string
    which we free at the end of the function.

    When RIP changes the vstat mode, also change the cursor

    When changing between 8 and 16 row fonts in RIP mode, the cursor
    start and end was left for the old font size... 16 -> 8 would leave
    the cursor one line below the current position, and 8 -> 16 would
    leave the cursor in the middle of the cell.

    This hacks the vstat deeper to fix up the cursor as well.

    Fix handling of broken CRLF pairs in RIP mode

    If telnet binary mode is enabled (the new default), and a CR and LF
    come in on separate recv() calls, the RIP parser would stop at the
    CR, and pass the LF back to the ANSI parser.

    Ah, dura-bbs.net, always pushing the limits.
