With this commit configuration via uci, similiar to the one used for
OpenVPN, will be added to tinc.
Most of the parameters are working just as described in the official
manpages of tincd and tinc.conf as provided by its developer.
The only exceptions are 'enable' which if set to 0 or if not set
will make the tinc init script completely ignore this tinc network and
its according tinc host configurations (similiar to the one in the
OpenVPN config) and 'generate_keys' which if set to 1 will check whether
a key pair is already present for the given tinc network and if not will
generate them with the key size of "key_size" (default if not present:
2048) - this reduces the "effort" of setting up a tinc VPN on a router
to just providing the right uci config file with no need of creating
custom initialization scripts for for instance the key generation.
Furthermore, similiar to the OpenVPN configuration, also tinc configs
of its native format can be used. They just need to be placed in
/etc/tinc/NETNAME. The init scripts will always copy the content of
/etc/tinc/ to /tmp first and will append any parameters provided in
/etc/config/tinc afterwards (the user needs to take care to not specify
non-list parameters in both uci and native config).
