This reverts fd784ccaf6 commit.
Thanks Stephen, but actually I think the last patch (increase clock
resolution) shouldn't go in yet. I'm not done yet looking at all
the compatibility issues and it does change the range of valid
values for everything dealing with times. Most places I looked
at still accept reasonable ranges, but I would feel more comfortable
to make sure everything is fine first.
[IPROUTE]: Increase internal clock resolution to nsec

[IPROUTE]: Replace "usec" by "time" in function names
Rename functions containing "usec" since they don't necessarily return
usec units anymore.

[IPROUTE]: Introduce TIME_UNITS_PER_SEC to represent internal clock resolution
Introduce TIME_UNITS_PER_SEC and conversion functions between internal
resolution and resolution expected by the kernel (currently implemented as
NOPs, only needed by HFSC, which currently always uses microseconds).

[IPROUTE]: Introduce tc_calc_xmitsize and use where appropriate
Add tc_calc_xmitsize() as complement to tc_calc_xmittime(), which calculates
the size that can be transmitted at a given rate during a given time.
Replace all expressions of the form "size = rate*tc_core_tick2usec(time))/1000000"
by tc_calc_xmitsize() calls.
