hbisect: add functions to return a label for a cset bisection status

Add two new functions that return a string containing the bisection status
of the node passed in parameter:
 - .label(node): return a multi-char string representing the status of node
 - .shortlabel(node): return a single-char string representing the status
   of node, usually the initial of the label

    bisection status    .label()            .shortlabel()
    ----------------------------------------------------------
    good                'good'              'G'
    good (implicit)     'good (implicit)'   'G'
    bad                 'bad'               'B'
    bad (implicit)      'bad (implicit)'    'B'
    skipped             'skip'              'S'
    untested            'untested'          'U'
    ignored             'ignored'           'I'
    (others)            None                None

There is no point in returning 'range' or 'pruned', as these get covered
by another, more meaningful status in the table above.

In case the node is not being bisected, the functions return None to leave
it up to the caller to decide what to print (nothing, an empty space, or
whatever else suits).
