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).

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.

ef9358c0d6 Improve starting/stopping tincd using tincctl. 
When starting tincd, tincctl now strips non-options from the command line, and
sets argv[0] to the name of the tincd command instead of copying its own
command name.

When stopping a running tincd, tincctl now waits for it to terminate.

1f312137d5 Allow dumping either directed or undirected graphs. 
Internally, tinc maintains a directed graph of the meta connections between
nodes. However, this causes graphviz to draw two lines between nodes, which is
not always desirable. The "dump graph" command now defaults to dumping an
undirected graph, the "dump digraph" command will dump a directed graph.

At the moment it just reproduces the old format.

a57db1dfe0 Fork when using the "start" command in tincctl. 
This allows the command to be given in its shell without immediatly exiting tincctl.

73348be58e Have tincctl act as a shell when no command is given. 
By default it uses readline to read commands. If the input and output are not a
tty, no prompt is shown.

6396f42d74 Stricter checks for netname and node names. 
- Node names should not be empty.
- Net names should not contain slashes or start with a dot, because they are
  used in pathnames.

68de7b481e When exporting configuration files, don't copy Name variables. 
These interfere with tincctl import. Besides, host configuration files should
not contain Name at all.

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.

344d6b9ac3 Let tincctl use the NETNAME environment variable if no -n option is given. 
This allows administrators who frequently want to work with one tinc
network to omit the -n option. Since the NETNAME variable is set by
tincd when executing scripts, this makes it slightly easier to use
tincctl from within scripts.
