Log:
 - Define OSKIT so we can use special oskit functions
 - Implement oskit buffer functions to track references and allocate buffers
 - Remove unneeded mbuf freeing hacks now that we track references (fixes random crashes
would occur when an mbuf was freed inside ip_output)
 - Remove the "ACK hack" that we used to hack around our loopback
implementation
 - Remove unneeded mbuf pool initialization
 - Remove unused code in sleep.c
