mbuf. First moves toward being able to cope better with having layer 2 (or
other encapsulation data) before the IP header in the packet being examined.
More commits to come to round out this functionality. This commit should
have no practical effect but clears the way for what is coming.

in a previous commit to avoid namespace collisions, unfortunately I missed two
of them. This leads to the ip alias being incorrectly removed in some cases
when using the stop command.

Redo the checking for 2.6 emulation. We now cache the value of
use26 and replace calls to linux_get_osrelease() + parsing with
