For some reason the edges ware removed in one direction resulting in e->reverse
point into invalid memory.
Do not insert edge into edge_weight_tree if not needed.
If ADD_EDGE came from tinc version 1.0.x local_address.sa.sa_family is set to 0.
If it came from tinc version 1.1.x forwarded for older verion it will be 255 - AF_UNKNOWN.
When tinc gets ADD_EDGE from older versions it will allocate
new edge in protocol_edge.c:189 due to missed case in lines 149-171 where
local_address is not defined.

The proper place to clean up resources of objects is in their
destructor. This makes sure proper cleanup when edge_del() is called as
well. At exit, free_edge() is called on all edges by free_edge_tree(),
which is called by exit_nodes().
Let configure include sys/if_tun.h when testing for netinet/if_ether.h
to detect the Kernel/libc header conflict on musl.
After this patch, configure will correctly detect netinet/if_ether.h as
unusable and the subsequent compilation will not attempt to use it.
Conflicts:
src/have.h
With AutoConnect = yes, tinc tries to establish connections to known hosts.
However, you could have set no Address for this host, which is perfectly fine
(as long as there is at least one bootstrap node with an address or a local
discovered node already part of the network)
So log this to LOG_DEBUG
In a "decentrally managed vpn" it is very likely that host config
files for some reachable nodes do not exist. Currently, tinc
fills the logs with "Cannot open config file" messages.
This commit changes the log level to LOG_DEBUG so
syslog doesn't get filled by default.
