Un-staticize 'dst' sockaddr in the stack of bpfwrite() to prevent
the need to synchronize access to the structure. I believe this
should fit into the stack under the necessary circumstances, but
if not we can either add synchronization or use a thread-local
malloc for the duration.

Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo

add a stub for bpfattach2 so bpf is not required with the 802.11
module or related drivers

Spotted by: Dan Lukes <dan@obluda.cz>

Reduce window during which a race can occur when detaching
an interface from each descriptor that references it. This
is just a bandaid; the locking here needs to be redone.

Change instances of callout_init that specify MPSAFE behaviour to
use CALLOUT_MPSAFE instead of "1" for the second parameter. This
does not change the behaviour; it just makes the intent more clear.
