        src/share/man/man4: ddb.4
        src/sys/ddb: db_command.c
        src/sys/kern: kern_history.c
        src/sys/sys: kernhist.h

Log Message:
extend the ddb "show kernhist" command.  the synopsis is now:

     show kernhist[/i] [addr[,count]]

the i modifier means display info instead of entries, and the count
restricts to the last count entries.

the count option is only supported for specified histories.  it
could be extended but requires more logic than the single history,
as multiple histories are merged during display.
