Clarify StrictSubnets.
Update the documentation of the tinc command.
Add index entries for the CLI commands.
Fix tinc-gui on Windows.
Ensure tinc-gui running in 64 bits mode can find tinc's 32 bit registry key.
Let tinc-gui use correct address family when connecting to tincd via TCP.
Document clearly that tinc depends on curses and readline libraries.
Document that 1.1 uses AES-256 in GCM mode.
Add the ListenAddress option.

ListenAddress works the same as BindToAddress, except that from now on,
explicitly binding outgoing packets to the address of a socket is only done for
sockets specified with BindToAddress.
Test two tinc daemons using network namespaces.

Testing multiple daemons connecting to each other on the same computer is
usually difficult, because connections to local IP addresses will bypass most
of the network stack. However, recent versions of Linux support network
namespaces, which can isolate network interfaces. We use this to isolate the
virtual interface of the daemons from each other, so we get the behaviour as if
the daemons were each running on their own machine. This can also be used for
more complicated tests (including those with firewall rules) without disturbing
the real network setup of the host computer.
Add missing newlines when copying variables from tinc.conf to an invitation file.
Don't ask questions if we are not running interactively.

When creating invitations or using them to join a VPN, and the tinc command is
not run interactively (ie, when stdin and stdout are not connected or
redirected to/from a file), don't ask questions. If normally tinc would ask for
a confirmation, just assume the default answer instead. If tinc really needs
some input, just print an error message instead.

In case an invitation is used for a VPN which uses a netname that is already in
use on the local host, tinc will store the configuration in a temporary
directory. Normally it asks for an alternative netname and then renames the
temporary directory, but when not run interactively, it now just prints the
location of the unchanged temporary directory.
Document Weight and also allow it to be set from tinc.conf.
Use addresses learned from other nodes when making outgoing connections.

Before, when making a meta-connection to a node (either because of a ConnectTo
or because AutoConnect is set), tinc required one or more Address statements
in the corresponding host config file. However, tinc learns addresses from
other nodes that it uses for UDP connections. We can use those just as well for
TCP connections.

Handle errors from TAP-Win32/64 adapter in a better way.

Before, the tapreader thread would just exit immediately after encountering the
first error, without notifying the main thread. Now, the tapreader thead never
exits itself, but tells the main thread to stop when more than ten errors are
encountered in a row.

Fix compiling for Windows.
Check whether OpenSSL has support for GCM.
