ff71f28902 Merge local host configuration with server configuration. 
With some exceptions, tinc only accepted host configuration options for the
local node from the corresponding host configuration file. Although this is
documented, many people expect that they can also put those options in
tinc.conf. Tinc now internally merges the contents of both tinc.conf and the
local host configuration file.

f75e71bc69 Convert Port to numeric form before sending it to other nodes. 
If one uses a symbolic name for the Port option, tinc will send that name
literally to other nodes.  However, it is not guaranteed that all nodes have
the same contents in /etc/services, or have such a file at all.

b455111184 Make MSS clamping configurable, but enabled by default. 
It can either be set globally in tinc.conf, or per-node in host config files.

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.

5cbddc68ba Use uint32_t instead of long int for connection options. 
Options should have a fixed width anyway, but this also fixes a possible MinGW
compiler bug where %lx tries to print a 64 bit value, even though a long int is
only 32 bits.

4c85542894 Drop support for localisation. 
Localised messages don't make much sense for a daemon, and there is only the
Dutch translation which costs time to maintain.

a227843b73 Remove checkpoint tracing. 
This feature is not necessary anymore since we have tools like valgrind today
that can catch stack overflow errors before they make a backtrace in gdb
impossible.

d5b56bbba5 Disable PMTUDiscovery in switch and hub modes. 
In switch and hub modes, tinc does not generate ICMP packets in response to
packets that are larger than the path MTU.  However, if PMTUDiscovery is
enabled, the IP_MTU_DISCOVER and IPV6_MTU_DISCOVER option is set on the UDP
sockets, which causes all UDP packets to be sent with the DF bit set, causing
large packets to be dropped, even if they would otherwise be routed fine.

046158a216 Use the crypto wrappers again instead of calling OpenSSL directly. 
This theoretically allows other cryptographic libraries to be used,
and it improves the readability of the code.

40731d030f 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.
