In Windows TAP driver, refactor DHCP/ARP packet injection code to
use a DPC (deferred procedure call) to defer packet injection until
IRQL < DISPATCH_LEVEL, rather than calling NdisMEthIndicateReceive
in the context of AdapterTransmit. This is an attempt to reduce kernel
stack usage, and prevent EXCEPTION_DOUBLE_FAULT BSODs that have been
observed on Vista. Updated TAP driver version number to 9.6.
