commit 0f2aa4bd8b698608876bec141c5aef1aa619730b

Releasing 1.0.16.
commit e16ead8dd9d4600664058069f0695832dfe068b2
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Sat Jul 23 14:11:44 2011 +0200
Use usleep() instead of sleep(), MinGW complained.
commit 50fcfea127c9d2fdf8894498a9fdcc6fb3bbb2ce
Author: Guus Sliepen <guus@tinc-vpn.org>
Date: Sun Jul 17 19:34:01 2011 +0200
Flush output buffer in send_tcppacket().
This is mainly important for Windows, where the select() call in the
main thread is not being woken up when the tapreader thread calls
route(), causing a delay of up to 1 second before the output buffer is
flushed. This would cause bad performance when UDP communication is not
possible.
commit be2fc8b0458b1e2ced3b5de410356d8d8639acff
Author: Guus Sliepen <guus@tinc-vpn.org>

Make code to detect two nodes with the same Name less triggerhappy.
First of all, if there really are two nodes with the same name, much
more than 10 contradicting ADD_EDGE and DEL_EDGE messages will be sent.
Also, we forgot to reset the counters when nothing happened.
In case there is a ADD_EDGE/DEL_EDGE storm, we do not shut down, but
sleep an increasing amount of time, allowing tinc to recover gracefully
from temporary failures.
