fix off-by-14 error in fragmentation
...
This was harmless since it simply meant our fragments were not as long
as they could be.

8 is better than 10
...
It's quite common for the real pmtu to be 8 less than what was
advertised.

drop maxpayload in conjunction with clientPMTU

pay attention to EMSGSIZE errors when sending pmtu verification packets
...
and drop the pmtu accordingly
This way, when we actually *do* get pmtu info from the network/kernel
we can discover the correct pmtu much more quickly. Especially in the
absence of other traffic, forwarding of which was previously the only
place where we'd check for EMSGSIZE.
Fixes #12
