8771a50b14 Fix TTL out-of-range bug
Was causing two routing tests to fail since the TTL decrement
logic was fixed in a8b88a46

The default TTL of 64 overflowed the 5-bit unsigned int in the MDP
packet header

2252fdcaa7 created tool for automatically finding IN()s without matching
OUT()s or where return() is used instead of RETURN().
Added OUT() to end of all functions using IN() that lacked it to
make it easier to statically analyse this invariant.
Fixed several return instead of RETURNs detected through use of
this tool. #49

69ae7e1706 prune some debugging.
avoid some segfaults due to lack of IP addresses in packet radio
native MDP payloads.
problems remain with SLIP encapsulation/extraction, but some packets
are already getting through.
