Remove the last two global variables that are used to store packet state while
it travels through the IP stack. This wasn't much of a problem because IP
source routing is disabled by default but when enabled together with SMP and
preemption it would have very likely cross-corrupted the IP options in transit.
The IP source route options of a packet are now stored in a mtag instead of the
global variable.
