Subject: [NET_SCHED 00/10]: ktime clocksource + hrtimer

These patches convert the packet schedulers to use ktime as only clock
source and kill off the manual clock source selection. Additionally all
packet schedulers are converted to use hrtimer-based watchdogs, greatly
increasing scheduling precision.

I've tested HFSC, HTB, TBF and netem. CBQ is untested since I never
managed to get it running properly even without these patches.

I have a number of follow-up cleanup patches that get rid of most of
the remaining PSCHED_* macros, I'll send them once these patches have
been merged.

Please apply, thanks.
