Nexthop calculation should always use the shortest path.
When tinc runs the graph algorithms and updates the nexthop and via pointers,
it uses a breadth-first search, but it can sometimes revisit nodes that have
already been visited if the previous path is marked as being indirect, and
there is a longer path that is "direct". The via pointer should be updated in
this case, because this points to the closest hop to the destination that can
be reached directly. However, the nexthop pointer should not be updated.
This fixes a bug where there could potentially be a routing loop if a node in
the graph has an edge with the indirect flag set, and some other edge without
that flag, the indirect edge is part of the minimum spanning tree, and a
broadcast packet is being sent.

Use the ChaCha-Poly1305 cipher for the SPTPS protocol.
The main reason to switch from AES-256-GCM to ChaCha-Poly1305 is to remove a

changes between versions. The source code for ChaCha-Pol1305 is small and in
the public domain, and can therefore be easily included in tinc itself.
Moreover, it is very fast even without using any optimized assembler, easily
outperforming AES-256-GCM on platforms that don't have special AES instructions

Testing multiple daemons connecting to each other on the same computer is
usually difficult, because connections to local IP addresses will bypass most

virtual interface of the daemons from each other, so we get the behaviour as if
the daemons were each running on their own machine. This can also be used for
more complicated tests (including those with firewall rules) without disturbing
the real network setup of the host computer.
