94587264bd Allow connections via UNIX sockets.
This is mainly useful for control connections. The client must still present
the control cookie from the PID file.

6bc5d626a8 Drop libevent and use our own event handling again.
There are several reasons for this:

- MacOS/X doesn't support polling the tap device using kqueue, requiring a
  workaround to fall back to select().
- On Windows only sockets are properly handled, therefore tinc uses a second
  thread that does a blocking ReadFile() on the TAP-Win32/64 device. However,
  this does not mix well with libevent.
- Libevent, event just the core, is quite large, and although it is easy to get
  and install on many platforms, it can be a burden.
- Libev is more lightweight and seems technically superior, but it doesn't
  abstract away all the platform differences (for example, async events are not
  supported on Windows).

ade4fccad6 Using alloca() for a constant sized buffer is very silly.
Cppcheck said using alloca() in the 21st century is silly anyway.

717ea66d7b Add the AutoConnect option.
When set to a non-zero value, tinc will try to maintain exactly that number of
meta connections to other nodes.  If there are not enough connections, it will
periodically try to set up an outgoing connection to a random node.  If there
are too many connections, it will periodically try to remove an outgoing
connection.

ff306f0cda Replace the connection_tree with a connection_list.
The tree functions were never used on the connection_tree, a list is more appropriate.
Also be more paranoid about connections disappearing while traversing the list.

e053713465 When terminating, keep control connections open until the end.
This ensures all device files and listening sockets have been closed before
tincctl gets notified of tincd's termination.

fb5588856f Add support for SOCKS 5 proxies.
This only covers outgoing TCP connections, and supports only
username/password authentication or no authentication.

b58d95eb29 Add basic support for SOCKS 4 and HTTP CONNECT proxies.
When the Proxy option is used, outgoing connections will be made via the
specified proxy. There is no support for authentication methods or for having
the proxy forward incoming connections, and there is no attempt to proxy UDP.

84531fb6e6 Allow broadcast packets to be sent directly instead of via the MST.
When the "Broadcast = direct" option is used, broadcast packets are not sent
and forwarded via the Minimum Spanning Tree to all nodes, but are sent directly
to all nodes that can be reached in one hop.

One use for this is to allow running ad-hoc routing protocols, such as OLSR, on
top of tinc.

8792b9a9f3 Remove confusing error message for failed reading in ECDSA keys.
Most likeley the error is that there just is no valid key inside the used
host file, and in this case errno just contains a random value from the
last previously failed call.

535a55100b Allow environment variables to be used for Name.
When the Name starts with a $, the rest will be interpreted as the name of an
environment variable containing the real Name. When Name is $HOST, but this
environment variable does not exist, gethostname() will be used to set the
Name. In both cases, illegal characters will be converted to underscores.

89f4574e0b Add support for systemd style socket activation.
If the LISTEN_FDS environment variable is set and tinc is run in the
foreground, tinc will use filedescriptors 3 to 3 + LISTEN_FDS for its listening
TCP sockets. For now, tinc will create matching listening UDP sockets itself.

There is no dependency on systemd or on libsystemd-daemon.

c373de2e98 Add support for multicast communication with UML/QEMU/KVM.
DeviceType = multicast allows one to specify a multicast address and port with
a Device statement. Tinc will then read/send packets to that multicast group
instead of to a tun/tap device. This allows interaction with UML, QEMU and KVM
instances that are listening on the same group.

8ac096b5bf Allow log messages to be captured by tincctl.
This allows tincctl to receive log messages from a running tincd,
independent of what is logged to syslog or to file. Tincctl can receive
debug messages with an arbitrary level.

8420a0c8bd Allow disabling of broadcast packets.
The Broadcast option can be used to cause tinc to drop all broadcast and
multicast packets. This option might be expanded in the future to selectively
allow only some broadcast packet types.

0233b1d710 Decrement TTL of incoming packets.
Tinc will now, by default, decrement the TTL field of incoming IPv4 and IPv6
packets, before forwarding them to the virtual network device or to another
node. Packets with a TTL value of zero will be dropped, and an ICMP Time
Exceeded message will be sent back.

This behaviour can be disabled using the DecrementTTL option.
