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.

4b3fd94b1c Improved --logfile option.
Instead of UNIX time, the log messages now start with the time in RFC3339
format, which human-readable and still easy for the computer to parse and sort.
The HUP signal will also cause the log file to be closed and reopened, which is
useful when log rotation is used. If there is an error while opening the log
file, this is logged to stderr.

8b3cc695b5 Don't ignore SIGCHLD, system() needs it.
But we do ignore SIGPIPE, and tinc 1.0.x signals that are no longer used
(SIGUSR1 and SIGUSR2), since the default handler of these signals is to
terminate tincd immediately.

e452a933f9 Simplify signal handling.
We don't override any signal handlers anymore except those for SIGPIPE and
SIGCHLD. Fatal signals (SIGSEGV, SIGBUS etc.) will terminate tincd and
optionally dump core.  The previous behaviour was to terminate gracefully and
try to restart, but that usually failed and made any core dump useless.

buffer, no memmove()s are performed. Only when adding to the buffer would
write past the end do we shift everything back to the start.

eacb5a28fb Increase threshold for detecting two nodes with the same Name.
In commit 4a21aabada, code was added to detect
contradicting ADD_EDGE and DEL_EDGE messages being sent, which is an indication
of two nodes with the same Name connected to the same VPN.  However, these
contradictory messages can also happen when there is a network partitioning. In
the former case a loop happens which causes many contradictory message, while
in the latter case only a few of those messages will be sent. So, now we
increase the threshold to at least 10 of both ADD_EDGE and DEL_EDGE messages.

0aa86d4b8b Do not set indirect flag on edges from nodes with multiple addresses.
Since tinc now handles UDP packets with a different source address and port
than used for TCP connections, the heuristic to treat edges as indirect when
tinc could detect that multiple addresses were used does not make sense
anymore, and can actually reduce performance.

cdbbbfabea Fix spurious misidentification of incoming UDP packets.
When a UDP packet was received with an unknown source address/port, and if it
failed a HMAC check against known keys, it could still incorrectly assign that
UDP address to another node. This would temporarily cause outgoing UDP packets
to go to the wrong destination address, until packets from the correct address
were received again.
