    rx: Define symbolic names for Rx magic numbers
    
    Since the original IBM code import, the magic number '6' has been used
    to specify the number of consecutive lost keepalives (ping acks) that
    indicate a dead connection.  By implication, this also defines the
    minimum number of seconds (at the minimum keeplive periodicity of 1
    second) before a connection may be considered dead.
    
    Define and use symbolic names for both uses of '6', and document their
    relationship.  Both have the same assigned value '6', but
    RX_PINGS_LOST_BEFORE_DEAD is use as an ordinal count, while
    RX_MINDEADTIME is expressed in units of seconds.
    
    The magic number '12' is used in a couple of places for the default
    value of rx_connDeadTime.  Give this constant a name
    (RX_DEFAULT_DEAD_TIME) and use it.
    
    No functional change is incurred by this commit.
