[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.

[IPROUTE]: Use tc_calc_xmittime() where appropriate

Replace expressions of the form "tc_core_usec2tick(1000000 * size/rate)"
by tc_calc_xmittime().

The CBQ case deserves an extra comment: when called with bnwd=rate,
tc_cbq_calc_maxidle() behaves identical to tc_calc_xmittime():

unsigned tc_cbq_calc_maxidle(...)
{
	double g = 1.0 - 1.0/(1<<ewma_log);
	double xmt = (double)avpkt/bndw;

	maxidle = xmt*(1-g);
	if (bndw != rate && maxburst) {
		...
	}
	return tc_core_usec2tick(maxidle*(1<<ewma_log)*1000000);
}

which comes down to:

maxidle	= xmt * (1 - g)
	= xmt * (1 - (1.0 - 1.0/(1 << ewma_log))
	= xmt * (1.0/(1 << ewma_log))

so:

maxidle * (1 << ewma_log) * 1000000
	= xmt * (1.0/(1 << ewma_log)) * (1 << ewma_log) * 1000000
	= xmt * 1000000
	= avpkt/bndw * 1000000

Which means tc_core_usec2tick(maxidle*(1<<ewma_log)*1000000) is identical
to tc_calc_xmittime(bndw, avpkt). Use it directly since its a lot easier
to understand its limits.

[IPROUTE]: tbf: fix latency printing

The calculated latency is already in usecs, the additional tick2usec
conversion breaks the calculation with jiffies or tsc clock source.

Example:

# tc qdisc add dev dummy0 root tbf latency 20ms burst 10k rate 50mbit
# tc qdisc show dev dummy0
qdisc tbf 8002: rate 50000Kbit burst 10Kb lat 15.4ms

Fixed:

# tc qdisc show dev dummy0
qdisc tbf 8002: rate 50000Kbit burst 10Kb lat 20ms

To support Mobile IPv6 RO, the following extension is included:
o Use XFRM_MODE_XXX macro instead of magic number
o New attribute option for all state: source address for
  deleting or getting message
o New attribute options for RO: care-of address, last-used timestamp
  and wild-receive flag

Note:
Flush command like `ip xfrm state flush` is to remove all XFRM state.
It has been effected for IPsec SAD but with this patch it flushes both
IPsec SAD and Mobile IPv6 RO states.
To make only IPsec SA flush, it is recommanded to specify each XFRM
protocol like below:
 `ip x s f proto esp ; ip x s f proto ah ; ip x s f proto comp`
