e012e752f4 Fix initialisation of packet decryption context broken by commit 3308d13e7e. 
Instead of a single, global decryption context, each node has its own context.
However, in send_ans_key(), the global context was initialised. This commit
fixes that and removes the global context completely.

Also only set status.validkey after all checks have been evaluated.

6698f7c390 Rename setup_network_connections() and split out try_outgoing_connections() 
In preparation of chroot/setuid operations, split out call to
try_outgoing_connections() from setup_network_connections()
(which was the last call in setup_network_connections()).
This is because dropping privileges should be done in-between
setup_network_connections() and try_outgoing_connections().

This patch renames setup_network_connections() to setup_network()
and moves call to try_outgoing_connections() into main routine.

No functional changes.

503c32eb0e Use a global list to track outgoing connections. 
Previously an outgoing_t was maintained for each outgoing connection,
but the pointer to it was either stored in a connection_t or in an event_t.
This made it very hard to keep track of and to clean up.

Now a list is created when tinc starts and reads all the ConnectTo variables,
and which is recreated when tinc receives a HUP signal.

67df7fb7e1 Only send packets via UDP if UDP communication is possible. 
When no session key is known for a node, or when it is doing PMTU discovery but
no MTU probes have returned yet, packets are sent via TCP. Some logic is added
to make sure intermediate nodes continue forwarding via TCP.  The per-node
packet queue is now no longer necessary and has been removed.

228e7a5c8f Apply patch from Scott Lamb adding an output buffer for the TCP sockets. 
This helps coalescing multiple send_meta() commands into one TCP packet.
Also limit the size of the output buffer before dropping PACKETs.
