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.

- Net names should not contain slashes or start with a dot, because they are

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.

bbc0ba9e87 use execvp() not execve() in tincctl start
sometimes argv[0] will have directory-less name (when the
command is started by shell searching in $PATH for example).
For tincctl start we want the same rules to run tincd as for
tincctl itself (having full path is better but if shell does
not provide one we've no other choice).  Previous code tried
to run ./tincd in this case, which is obviously wrong.

This is a fix for the previous commit.

a7556a9d2c run tincd from the same directory as tincctl and pass all options to it
For tincctl start, run tincd from dirname($0) not SBINDIR -
this allows painless alternative directory installation and
running from build directory too.

Also while at it, pass the rest of command line to tincd, not
only options before "start" argument.  This way it's possible
to pass options to tincd like this:
  tincctl -n net start -- -d 1 -R -U tincuser ...

And also add missing newline at the end of error message there.

ab4d289faf Make pid files backwards compatible and add address of listening socket.
The pid is now written first, so that a version 1.0.x tincd can be used to stop
a running version 1.1 tincd.  Getsockname() is used to determine the address of
the first listening socket, so that tincctl can connect to the local tincd even
if AddressFamily = ipv6, or if BindToAddress or BindToInterface is used.

BindToAddress options.

edebf579f2 Use the TCP socket infrastructure for control sockets.
The control socket code was completely different from how meta connections are
handled, resulting in lots of extra code to handle requests.  Also, not every
operating system has UNIX sockets, so we have to resort to another type of
sockets or pipes for those anyway.  To reduce code duplication and make control
sockets work the same on all platforms, we now just connect to the TCP port
where tincd is already listening on.

To authenticate, the program that wants to control a running tinc daemon must
send the contents of a cookie file. The cookie is a random 256 bits number that
is regenerated every time tincd starts. The cookie file should only be readable
by the same user that can start a tincd.

Instead of the binary-ish protocol previously used, we now use an ASCII
protocol similar to that of the meta connections, but this can still change.
