Since it uses the same function for executing everything,

Offset the fwmarks used in load-balancing to avoid conflicts with
routing tables created by policy based routing. Originally from

This reverts commit e9001877d3bbdd5c4c48f0ccc088bd381d0b92dc.
Since the upstream change in the kernel from 3.6 onwards, where the
ipv4 routing cache has has been removed due to performance
bottlenecks and the fact that it was reasonable easy to launch denial
of service attackes (it was designed in friendlier times), the kernel
now reverts back to round-robin per packet routing rather than per flow
as it was previously, with the result that this commits breaks
load-balancing with two active routes.

Add the ability to run a user defined script to determine wan load-balancing interface health
includes sample http test (scripts/http_test.pl). Configuration will look as follows:
wan {
interface-health eth0 {
nexthop 10.3.0.1
test 1 {
test-script /tmp/http_test.pl
type user-defined
}
}
interface-health eth1 {
nexthop 10.3.0.1
test 1 {
test-script /tmp/http_test.pl
type user-defined
}
}
With corresponding output:
vyatta@vyatta# run show wan-load-balance
Interface: eth0
Status: active
Last Status Change: Wed Mar 30 19:03:59 2011
+Test: user Script: /tmp/http_test.pl

-Test: user Script: /tmp/http_test.pl
Last Interface Success: n/a
Last Interface Failure: 0s
# Interface Failure(s): 52
Scripts returns 0 for success, non-zero for failure.

When checking policy route compare nexthop and interface rather then just checking for an entry. This allows for incorrect entries to be replaced. This would be
a problem if different nexthop is readvertised via dhcp to the interface.
