[headsup] call for assistance with ports broken on -current

[Mark Linimon]

With 8.0 coming up, it's time to take a look at the ports that have
been broken by some recent changes to freebsd-current.  I have put
a list of these ports, categorized by which change, on the wiki at
http://wiki.freebsd.org/PortsBrokenOnCurrent.

These changes are: tty changes, jail changes, import of strndup(3),
ARP v2, libusb20.  (The latter has not yet been run through pointyhat,
and is probably incomplete.)

Any help fixing these will be appreciated.
