30b2059608 Fix -Wunused-parameter warnings 
New UNUSED(param) macro suppresses the warning for a specific parameter

In some cases, removed the unused parameters.  In others, used the
parameter in a DEBUGF() or assert() statement to document the intent.

dafa1fc186 Improve struct socket_address 
Add struct sockaddr_in 'inet' union field, rename 'addr_un' union field
to 'local'

Replace recvwithttl()'s (struct sockaddr *) and socklen_t pair of args
with single (struct socket_address *) arg

a9ccd38adc Improve overlay buffer ob_xxx() primitives 
All ob_append_xxx(b,...) functions return void

ob_makespace() returns 1 if successful, 0 if not

Add ob_overrun(b) predicate to check for overrun after any number of
appends

a95ef79139 Use sid_t everywhere 
Remove stowSid() at last

Change API of tohex() and strbuf_tohex(), to pass string length instead of
binary byte count.  This allows odd numbers of hex digits to be produced.

Remove alloca_tohex_sid(); replace with alloca_tohex_sid_t()

New alloca_tohex_sid_t_trunc() macro

9ba08e465f Issue #11: use socklen_t instead of int where appropriate 
Also check for valid recvaddrlen before processing a received MDP packet.

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.
