top: proc summary mismatch

[Dmitry Lohansky]

Good time of day.

As defined in sys/proc.h process may have one of this states:

enum procstat {
        SIDL = 1,
        SACTIVE = 2,
        SSTOP = 3,
        SZOMB = 4,
};

For display summary process info 'top' use procstatenames array with values:
"", " starting, ", " running, ", " sleeping, ", " stopped, ", " zombie, "
which are not mapped to process's states.

There is a patch fo fix this promblem. It also display processes with
sleeping lwp as sleeping, for example:

37 processes:  1 running, 36 sleeping

But is more better mark process as sleeping only if _all_ of this lwps
are in sleeping state.
