5b07039b07 Rename xmalloc_and_zero() to xzalloc(). 
The former name is more or less only used by tinc, the latter is used by other
projects as well, and shorter as well.

9b9230a0a7 Use conditional compilation for cryptographic functions. 
This gets rid of the rest of the symbolic links. However, as a consequence, the
crypto header files have now moved to src/, and can no longer contain
library-specific declarations. Therefore, cipher_t, digest_t, ecdh_t, ecdsa_t
and rsa_t are now all opaque types, and only pointers to those types can be
used.

43c72093ad Don't try to create tinc.conf when using set or add commands. 
It is almost certainly an error. If one really wants to create a new tinc.conf
file, one should use the init command.

af77e5d475 Allow changing configuration with tincctl without the "config" keyword. 
This saves typing some characters, and forces one to be more explicit about the
desired command (get, set).

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.

b50a92d0c3 Add the tincctl exchange and exchange-all commands. 
These are identical to an export/export-all followed by an import, and make
it simpler to exchange host config files with other nodes.

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.

By default it uses readline to read commands. If the input and output are not a
tty, no prompt is shown.

- 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.
