b6ce063b04 irqtop/lsirq: support softirq 
Add '-S' or '--softirq' for irqtop/lsirq, instead of interrupts, show
softirqs infomation. Because there is no more description of softirq,
do not show 'NAME' column by default.

44e39c9940 irqtop: cleanup sort stuff 
* user "cmp" in the function names (it does not sort)
* keep all in irq-common.c
* use column names on command line (e.g. --sort NAME)
* hardcode default to sort_result()
