src/net_socket.c: Bind outgoing TCP sockets to `BindToAddress'.
If a host has multiple addresses on an interface, the source address of the TCP
connection(s) was picked by the operating system while the UDP packets used a
bound socket, i. e. the source address was the address specified by the user.
This caused problems because the receiving code requires the TCP connection and
the UDP connection to originate from the same IP address.
This patch adds support for the `BindToInterface' and `BindToAddress' options
to the setup of outgoing TCP connections.

Thanks to Sven-Haegar Koch for spotting the bug and providing a fix.

Use a control socket directory to restrict access
This provides reasonable security even on Solaris. The sysadmin is
responsible for securing the control socket's ancestors from the
grandparent on.
We could add a cryptographic handshake later if desired.

Reload configuration through control socket
I also kept the SIGHUP handler, which many people will expect to see.
The control socket is better, though - it will tell you if there is a
problem.

sighup_handler was expecting the connection_tree to stay the same across

Temporarily revert to old crypto code
(The new code is still segfaulting for me, and I'd like to proceed with other
work.)
This largely rolls back to the revision 1545 state of the existing code
(new crypto layer is still there with no callers), though I reintroduced
the segfault fix of revision 1562.
