cd5f222cc4 Remove use of strcpy() and sprintf(). 
Even though they were safe, compilers like to warn about them nowadays.

d4410d0cce Don't assume sa.sa_family is a short int. 
Because FreeBSD's compiler complained about it.

ed09fa4e03 Fix version_get.h generation on BSD. 
It doesn't like .PHONY rules that are actually doing stuff. So make a really
phony rule that does nothing and depend in it in the version_git.h rule.

9527622abc Enable silent builds by default. 
Cleaner build messages make it easier to spot compiler warnings and errors.
Use make V=1 to get the verbose output back.

2a7871990b Update "now" after connect() when making outgoing connections. 
It could be that address resolution takes a long time, don't let that
count against a connection. This is especially important when using a
nameserver from the VPN.

cadbf587a0 Never call putenv() with data on the stack. 
Even though we are using putenv() here to remove items from the
environment, there is no guarantee that putenv() doesn't add the
argument to the environment anyway. In that case, we have to make sure
that it doesn't go away. We also don't want a memory leak, so keep a
list of things we unputenv()ed around, so we can reuse things.

Thanks to Poul-Henning Kamp for pointing out this problem.

Also remember ToS/DiffServ priority for each socket individually. This

1ceea259c3 Add warnings for bad combinations of Device and Interface. 
On Linux, the name of the tun/tap interface can be set freely. However,
on most other operating systems, tinc cannot change the name of the
interface. In those situations, it is possible to specify a Device and
an Interface that conflict with each other. On BSD, this can cause
$INTERFACE to be set incorrectly, on Windows, this results in a
potentially unreliable way in which a TAP-Win32 interface is selected.

92203bdbcb Fix source IP address for ICMP unreachable packets generated by tinc. 
Try to send ICMP unreachable replies from an address assigned to the
local machine, instead of the destination address of the original
packet.

The address is found by looking up the route towards the sender of
the packet that generated the error; in usual configurations, this
is the tinc interface.

This also fixes the traceroute display in mtr when using the
DecrementTTL option.

a8a3a2c8ce Fix DecrementTTL option. 
The option was not actually working, as it could be seen on traceroute or mtr.

The problem is that it was checking if the TTL was < 1 (so equal to 0) before decrementing it.

This meant that a packet with a TTL of 1 was being sent with a TTL of 0 on the VPN, instead of being discarded with the ICMP error message.
