    dtc: allow a label: in any dts context
    
    Change the lexer to recognise a label in any context.  Place
    before other celldata and bytestrings to avoid the initial
    characters being stolen by other matches.
    
    A label is a character sequence starting with an alphabetic
    or underscore optinally followed by the same plus digits and
    terminating in a colon.
    
    The included terminating colon will prevent matching hex numbers.
