add receive timeout argument

don't steal others' EIDs!
fix sync receive

boost::bind did not puke on binding a temporary to T&, so this went

object by reference.

fixes #156
fix some address handling weirdness

* don't send from :: source (uip6.c)
* don't send udp packets from an unallocated connection (udp_handler.c)
* don't force addresses to available needlessly (value_broadcast.c)
properly sequence udp_handler reset and statemachine reset broadcast
add syslog()-like infrastructure for debugging
use syslog() almost everywhere

trying hsv color magic
