[IPROUTE2]: Update pkt_sched.h (to resemble the kernel one)
Extend the tc_ratespec struct, with two parameters: 1) "cell_align"
that allow adjusting the alignment of the rate table. 2) "overhead"
that allow adding a packet overhead before the lookup in the kernel.
This is done in order to, add support to changing the rate table to
use the upper-boundry L2T (length to time) value. Currently we use the
lower-boundry, which result in under-estimating the actual bandwidth
usage.

Okay, but don't need a special patch to do it. I perodically sync
up the headers before each release.
